Who wants to sleep on a firm mattress? If you’re someone with a bigger body, a stomach sleeper, or if you hate the comfy sink of your bed, a firmer mattress might be the best fit for you. Firm doesn’t necessarily mean “uncomfortable,” and sometimes the extra support provided by a firm bed can help you sleep more soundly.
Our testers have tried the majority of the best mattresses on the market — more than 330 total. Many of these mattresses claim to be firm, but we’ve done the work to give you our top picks in this category.
Firmness can be pretty subjective, but we consider a bed from all angles, taking into account body type, sleeping position, and other personal preferences that factor into who a bed is best for. We’ve helped more than 62,000 people find their favorite mattress over the years, so a new one is definitely in the stars for you. Keep reading to find out more about the best firm mattresses.

How We Picked the Best Firm Mattresses
Firmness is a score from 1 to 10 letting the shopper know how soft or firm a bed is. Our firmness scale is based on the objective rankings of multiple Certified Sleep Science Coaches here at Sleepopolis.
Though this list features a bunch of mattresses with varying construction and performance features, all of them share one thing: They all have models that earn at least a 7 out of 10 on our firmness scale. We consider anything over 6.5, the industry standard for medium-firm, a firm mattress.
Response is a close cousin to bounce. The more responsive a mattress is, the easier it is to move around on.
We test responsiveness by seeing how easy it is to move around on the bed’s surface, then give it a score out of 5. Most firm beds will also have a higher responsiveness score, as a doughy feel that restricts movement is often associated with softer mattresses.
Support is important in all mattresses, but firm beds tend to be champions at this, as they prioritize firm foundations that yield a more lifted sleep surface.
While we don’t have an official support rating, our testers judge whether a mattress is supportive by considering their spinal alignment when they rest on the bed. If they feel comfortably aloft with no awkward angles or pressure buildup, it’s safe to say that the bed is supportive for that position or body type.
We’ve developed a rigorous testing methodology that tells us how each mattress performs and who it might be a good fit for. All the beds on this list have been evaluated for pressure relief, cooling performance, responsiveness, edge support, and more.
Our team of certified sleep science coaches has tested more than 500 mattresses over the last decade, allowing us to guide more than 145,000 people to the best mattress for them. Not only do we use and evaluate these products ourselves, but we also consult with doctors and other professionals to ensure we keep up to date with the latest in sleep science and medicine. For example, Dr. Joe Tedesco (DPT, OCS, ATC, CSCS) comes into our studio to personally test mattresses and give a medical perspective on each product.

Plank Firm Luxe – Best Firm Mattress Overall
The Plank Firm Luxe is not only unique in that it’s one of the firmest mattresses out there, but it’s also flippable. Each side boasts sturdy support, reinforced with a core layer of pocketed coils. Additionally, the option to test out which side is best for you should largely appeal to back, stomach, combination sleepers, and those with larger body types. It’s also the luxury upgrade version of the standard Plank Firm, so it has some added cushioning foam and a slightly plusher feel, as well as the springs (the standard Plank Firm is all-foam). For more information, check out our video review.
What our tester says:
“The Plank Firm Luxe has a very similar feel to the Plank Firm mattress, except the firm side on the Plank Firm Luxe is the softest, plushest side either bed offers. I like that it has a little more versatility.” – Nichole Mondshein, lead reviewer and mattress tester
Why It’s the Best Firm Mattress Overall
- This flippable hybrid bed combines two firm mattresses in one: an extra-firm side and a more “traditional” firm side.
- Both sides of this bed are firm; the extra-firm side comes out to 7.5 out of 10 on our firmness scale, while the firm side inches closer to medium-firm at 7 out of 10.
- The Plank Firm Luxe boasts excellent motion isolation for a firm bed, as well as plenty of responsiveness from its coils and supportive layers.
How Did It Perform During Testing?
Firm Side
Motion Isolation: 5/5
The memory foam layer closer to the Firm side did a fantastic job of dampening motion.
Cooling: 3.5/5
Our testers found the Firm side initially cool to the touch, but it retained some body heat over time.
Response: 4.5/5
The Firm side is only slightly less responsive than the Extra Firm due to the foam layer.
Edge Support: 3.5/5
The edge support on the Firm side is mostly average; however, you can lie on it with falling off.
Pressure Relief: 4.4/5
The Firm side of the luxe Plank has exceptional pressure relief for back sleepers.
Firmness: 7/10
The Firm side of the Plank is only slightly firmer than the industry average of medium-firm (6.5).
Extra-Firm Side
Motion Isolation: 4.7/5
Despite being closest to the springy coils, the Extra Firm side has surprisingly solid motion isolation for couples.
Cooling: 3/5
During testing, our team found that the cooling on the Extra Firm side was about average.
Response: 5/5
The Extra Firm side is closest to the innerspring coils, making it is highly responsive to movement and ideal for combination sleepers.
Edge Support: 3.2/5
We found more sinkage on the edge of the Extra Firm side; its performance here was about average.
Pressure Relief: 3.8/5
The Extra Firm side provides less cushioning, meaning some side sleepers may experience pressure buildup.
Firmness: 7.5/10
Most sleepers will find that the Extra Firm side is significantly firmer than most mattresses.
Dr. Tedesco’s Notes
“This is a firm mattress that doesn’t really provide substantial pressure relief,” Dr. Joe Tedesco said as he lay down on the Plank Firm Luxe. “You have to really want a firm bed to enjoy it.” However, he found the mattress fairly comfortable for back sleeping: “Though I’m not getting any contouring in the lumbar spine, I still feel supported and don’t have pressure buildup in my pelvis,” he explained.
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | unpleasant | good | excellent |
| Average (130-230 lbs) | unpleasant | excellent | excellent |
| Heavy (over 230 lbs) | good | excellent | excellent |
| Body Weight: Light (under 130 lbs) | |
|---|---|
| Side Sleeper | unpleasant |
| Back Sleeper | good |
| Stomach Sleeper | excellent |
| Body Weight: Average (130-230 lbs) | |
| Side Sleeper | unpleasant |
| Back Sleeper | excellent |
| Stomach Sleeper | excellent |
| Body Weight: Heavy (over 230 lbs) | |
| Side Sleeper | good |
| Back Sleeper | excellent |
| Stomach Sleeper | excellent |
Our Expert Opinion
If you want a new firm bed and don’t know where to look, the Plank Firm Luxe is a great place to start. This flippable hybrid features two firm feels in one, so sleepers can choose between an ultra-firm lift and a more approachable firmness. Each should provide excellent support and alignment.
This is a bouncy mattress that still surprisingly absorbs motion despite its lack of thick comfort layers. However, the edge support on a firm bed was surprisingly lackluster.
Choose the Plank Firm Luxe if …
- Stomach or back are your preferred sleeping positions. These positions will reap the most comfort from the Plank Firm Luxe’s firmer feel. Both sides should offer good support, but back sleepers may prefer the “traditional” firm side.
- You’re a combination sleeper. Both sides of this bed were also super bouncy, so moving around on the mattress won’t be an issue.
Keep looking if …
- Spreading out or sitting along the edge of your mattress is a go-to move. Our testers noticed quite a lot of sinkage in our edge support evaluation, despite the Plank Firm Luxe’s extra-firm feel. Nor was there a discernible difference between either side. For better edge support, I recommend the Saatva Classic.
- You’re a side sleeper. Most side sleepers, especially those under 230 pounds, will find this bed a bit too unyielding. They’ll want something softer for better pressure relief around the hips and shoulders.

Helix Dawn – Best Firm Hybrid Mattress
The Helix Dawn is one of the firmest mattresses offered by the company. Its construction provides good comfort for heavy people and stomach sleepers, both of whom need extra support to keep from sinking uncomfortably below the mattress surface. Like the other Helix mattresses, it can be upgraded to the Luxe version if you’re willing to pay a little extra for luxury features. To learn more, check out our video on Helix mattresses.
What our tester says:
“I really appreciate how supportive these mattresses are. Stomach sleepers, back sleepers, and heavy people (those over 250 pounds) could all benefit from the firm feel of this bed. No matter which model you choose, the Helix Dawn really delivers on lumbar support.” Logan Block, former Sleepopolis content director and mattress tester
Why It’s the Best Firm Hybrid Mattress
- We rated the Helix Dawn at 7 out of 10 on our firmness scale, a half-step up from medium-firm.
- As a hybrid mattress, this bed contains both foam and coils, though we felt the latter more, hence its perfect responsiveness score.
- This bed also earned a 4 out of 5 for both cooling and edge support.
How Did It Perform During Testing?
Motion Isolation: 3/5
On the Helix Dawn, you’ll likely feel your partner’s movements travel to your side of the bed.
Cooling: 4/5
When our tester lay on the surface of this mattress, he could feel it warm up, but never to the point of overheating.
Response: 5/5
Moving around on the Helix Dawn took no effort at all.
Edge Support: 4/5
We noticed a bit more sinkage when seated on the Helix Dawn, but lying down on them felt much more secure.
Pressure Relief: 3/5
Only some back sleepers may find the pressure relief they need on the Helix Dawn.
Firmness: 7/10
At 7 out of 10 on our firmness scale, the Helix Dawn has a somewhat firmer feel.
Dr. Tedesco’s Notes
Dr. Joe Tedesco likened the Helix Dawn to “a firm mattress with a soft topper.” Still, he found the mattress “more comfortable on the side than the back.” He added, “I’d give it a 4.5 for side sleepers, and those with lower back pain will especially like this. I can feel my body relaxing in this position. Helix is doing something right with this pillow top.”
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | unpleasant | unpleasant | excellent |
| Average (130-230 lbs) | unpleasant | good | excellent |
| Heavy (over 230 lbs) | unpleasant | excellent | good |
| Body Weight: Light (under 130 lbs) | |
|---|---|

Our Expert Opinion
The Helix Dawn is one of the firmer beds in Helix’s line of core hybrids. Its combination of foam and coils yields the perfect profile for stomach sleepers (and some who rest on their back!) looking to feel lifted on their bed’s surface.
We awarded this bed multiple scores of 4 or higher, including responsiveness, cooling, and edge support. This makes it a good choice for folks who want a balanced-feeling hybrid that ticks all the boxes. However, its motion isolation and pressure relief are a bit subpar — as to be expected of many firm beds.
Choose the Helix Dawn if …
- You’re a stomach sleeper. Stomach sleepers often prefer firmer beds, as they need more support to prevent their hips from sinking. Helix designed this firm mattress for back and stomach sleepers, though our testers found the latter position the most comfortable.
- It’s a good mattress for sex that you’re looking for. Our testers were able to roll around without feeling impeded by this bed, thanks to its firmer feel and flat top. This means easy repositioning during sleep or sex.
Keep looking if …
- Side sleeping is your preferred way to tuck in at night. None of our testers found the Helix Dawn comfortable in this position. It’s likely too firm to ensure the proper sinkage around the hips and shoulders.
- You’re a light sleeper. Based on the results of our partner test, I wouldn’t recommend this mattress to folks who share the bed. If you want to sleep soundly and remain undisturbed by your partner’s tossing and turning, check out the Nolah Evolution.

DreamCloud Memory Foam – Best Affordable Firm Mattress
Even though it’s an all-foam mattress, we found the DreamCloud Memory Foam mattress to be firm, supportive, and responsive. This makes it the rare foam bed that’s sturdy and bouncy enough for back sleepers, stomach sleepers, and combo sleepers alike. Learn more in our DreamCloud Memory Foam video review.
What our tester says:
“I think back sleepers should find a lot to love in the DreamCloud Memory Foam mattress. It’s supportive and sturdy, but still offers some comfort from the quilted cover. Many stomach sleepers should also enjoy how the firm foams in this bed keep their hips propped up for spinal alignment.” – Amelia Jerden, senior staff writer
Why It’s the Best Cheap Firm Mattress
- You can buy a queen-size DreamCloud Memory Foam mattress for under $800
- At 7 out of 10 on our firmness scale, this bed has a slightly firmer, “on top” feel that we don’t often see from all-foam mattresses.
- The DreamCloud Memory Foam never scored lower than a 4 out of 5 in all of our testing categories.
How Did It Perform During Testing?
Motion Isolation: 4.7/5
Even when someone got in and out of bed, our tester couldn’t really feel it.
Cooling: 4/5
Our tester never noticed the mattress heating up during our cooling test.
Response: 4.5/5
For an all-foam bed, the DreamCloud is pretty responsive, making it easier to move around on.
Edge Support: 4.2/5
The edges of the DreamCloud Memory Foam only slightly dipped when we sat on them.
Pressure Relief: 4.3/5
Both side and back sleepers should glean plenty of pressure relief from this bed, though the latter group will likely feel more comfortable overall.
Firmness: 7/10
The DreamCloud Memory Foam feels a little firmer than true medium-firm.
Dr. Tedesco’s Notes
Dr. Joe Tedesco noted that you won’t get much cradling with the DreamCloud Memory Foam mattress, but it’s plenty supported. He especially enjoyed sleeping on his back on this mattress: “I’m on top of the bed, and it’s holding me in the right position,” he said. “I’m not feeling myself sinking in — perfectly supported from nose to toes.”
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | good | excellent | good |
| Average (130-230 lbs) | good | excellent | unpleasant |
| Heavy (over 230 lbs) | good | good | unpleasant |
| Body Weight: Light (under 130 lbs) | |
|---|---|
| Side Sleeper | good |
| Back Sleeper | excellent |
| Stomach Sleeper | good |
| Body Weight: Average (130-230 lbs) | |
| Side Sleeper | good |
| Back Sleeper | excellent |
| Stomach Sleeper | unpleasant |
| Body Weight: Heavy (over 230 lbs) | |
| Side Sleeper | good |
| Back Sleeper | good |
| Stomach Sleeper | unpleasant |
Our Expert Opinion
Looking for an affordable bed under $1,000? You’ve found it in the DreamCloud Memory Foam mattress. This bed isn’t just reasonably priced; it’s well-made and well-rounded, earning 4s and above across the board in our testing — including high marks for motion isolation, responsiveness, and pressure relief.
It’s between medium-firm and firm on our firmness scale, a good option for sleepers who like an extra boost when they lay on their back or side. However, it’s still not firm enough for many stomach sleepers.
Choose the DreamCloud Memory Foam if …
- You switch between your back and side. Between our pressure relief and responsiveness test results, the DreamCloud Memory Foam mattress is a dream for this category of combination sleepers. They’ll enjoy the slightly firmer feel and how easy it is to transition between each position.
- A partner or pet shares the bed with you. Our tester could barely notice when another person was in bed alongside them. If you’re a light sleeper, you likely won’t wake from any movements on this mattress.
Keep looking if …
- You’re a stomach sleeper. Unless you weigh under 130 pounds, it’s unlikely the DreamCloud Memory Foam will be a match for stomach sleeping. Check out the Helix Dawn mattress instead.
- A true memory foam feel is your preference. You won’t sink deeply into this mattress as you would a traditional memory foam bed. This feeling is associated with softer foam beds.
For more information about this bed, read our full DreamCloud Memory Foam mattress review.
WinkBed – Best Firm Mattress for Back Pain
The WinkBed is a luxury hybrid mattress. It has a similarly supportive and sturdy feel to a traditional innerspring mattress, but upgrades like a Euro top and cooling Tencel cover give it a touch of modern luxury. Available in three firmness levels, there is a WinkBed for just about every sleeper. And a responsive and bouncy feel makes it a great pick for combination sleepers. Learn more in our video review.
What our tester says:
“If you like the feel of a traditional innerspring mattress, the WinkBed could work for you. Since this bed offered great pressure relief around my lumbar region, I’d also recommend it to folks who suffer from lower back pain.” – Nichole Mondshein, lead reviewer and staff writer
Why It’s the Best Firm Mattress for Back Pain
- The WinkBed is available in multiple firmness options, including a Firm model that should feel around 7.5 on our scale.
- Our expert team, including chief medical product tester Dr. Joe Tedesco, gave this bed the thumbs-up for spinal alignment and cushioning, which should help with back pain.
- This mattress also earned high marks for motion isolation, edge support, and pressure relief for back sleepers.
How Did It Perform During Testing?
Motion Isolation: 4.3/5
Our tester didn’t notice much movement during our ripple test.
Cooling: 3.5/5
Our cooling test found that the WinkBed did not excel at temperature regulation.
Response: 3/5
It was a little difficult to move around on the WinkBed, despite its hybrid construction.
Edge Support: 4.4/5
We found the WinkBed’s edges to be very strong.
Pressure Relief: 3.8/5
While pressure mapping the WinkBed, our testers found some pressure buildup on their side.
Firmness: 6.5/10
The Luxury Firm WinkBed has a medium-firm feel.
Dr. Tedesco’s Notes
Dr. Joe Tedesco thought the WinkBed was a fine option for any sleeping position and that it should help prevent or relieve back pain in each. “If you’re a back or a side sleeper, you’ll feel even support across your entire body. I didn’t feel any pressure buildup,” he explained. “If you’re a stomach sleeper, I still think you’ll feel well-enough supported that you won’t experience significant back pain,” he added. “The soft top allows you to sink in just enough, but it isn’t so soft that you dip too low.”
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | good | excellent | excellent |
| Average (130-230 lbs) | good | excellent | unpleasant |
| Heavy (over 230 lbs) | good | good | unpleasant |
| Body Weight: Light (under 130 lbs) | |
|---|---|
| Side Sleeper | good |
| Back Sleeper | excellent |
| Stomach Sleeper | excellent |
| Body Weight: Average (130-230 lbs) | |
| Side Sleeper | good |
| Back Sleeper | excellent |
| Stomach Sleeper | unpleasant |
| Body Weight: Heavy (over 230 lbs) | |
| Side Sleeper | good |
| Back Sleeper | good |
| Stomach Sleeper | unpleasant |
Our Expert Opinion
We tried out the mid-range model of the WinkBed and found it felt truly medium-firm as described, so it follows that the Firm should be no different. Either way, with this bed, you’re getting a luxurious-feeling hybrid with robust coils and a thick pillow top. We found out that support is the name of the game with this mattress.
The WinkBed also earned praise for its impressive motion isolation and strong edge support. However, for a hybrid, and a firm one at that, it’s not the bounciest.
Choose the WinkBed if …
- You sleep on your back and have back pain. This was the favored position among our testing team, with many claiming the WinkBed’s balanced feel was enough to convert them to sleeping on their back full-time.
- Spreading out when you sleep is what your dreams are made of. Our testers were able to lie along the edges of the WinkBed without much sinkage, leaving them feeling stable.
Keep looking if …
- You’re a side sleeper. The Luxury Firm model of the WinkBed was too firm to relieve pressure for side sleepers, so I doubt the Firm version will be much better.
- You like a bouncy bed. The thick comfort layers on top were enough to muffle the WinkBed’s coils, resulting in a kneading-dough sensation when we tried to move around. For a bed that’s both responsive and firm, check out the Plank Firm Luxe.

Saatva – Best Firm Mattress for Stomach Sleepers
The Saatva’s coil-on-coil construction provides a classic innerspring feel. It’s a good option for combo sleepers, who will want to feel free to switch positions and avoid feeling “stuck” in the mattress. It comes in three firmness levels, so you should be able to find one that suits your needs. The white glove delivery Saatva provides is an added perk and will save you the headache of getting rid of your old mattress (they take it away for free!). For more information, watch our video review.
What our tester says:
“I think the Saatva is a great option for back sleepers, as the Luxury Firm model provides enough cushioning for their lumbar region, but also lots of support to keep their spine in a neutral alignment.” – Nichole Mondshein, lead reviewer and staff writer
Why It’s the Best Firm Mattress for Stomach Sleepers
- We tried out the Luxury Firm model of the Saatva Classic and rated it at 7.5 out of 10 on our scale — decidedly firm.
- The Classic is a good match for most sleeping positions, but stomach sleepers especially should enjoy this bed’s lifted feel.
- This bed also boasts a super-bouncy feel and rock-solid edge support.
How Did It Perform During Testing?
Motion Isolation: 2.7/5
Our tester could feel a lot of his partner’s movement on the Saatva.
Cooling: 4/5
This bed has a temperature-neutral feel.
Response: 5/5
The Saatva’s innerspring feel makes it super bouncy and easy to move around on.
Edge Support: 4.8/5
The perimeter of the Saatva Classic is rock-solid.
Pressure Relief: 4/5
Pressure relief is better for back sleepers than side sleepers on this bed.
Firmness: 7.5/10
The Luxury Firm model of the Saatva Classic has a firmer feel.
Dr. Tedesco’s Notes
“When you lie on your stomach, oftentimes your back wants to arch,” Dr. Joe Tedesco explained. “But the springs in the Saatva Classic provide enough support so you don’t actually sink into the mattress much to create that arch.” He generally liked the bed for stomach sleepers, rating it a 4.5 out of 5 for this position. He added, “I’m not anteriorly tilted at all; in fact, I’m still pretty neutral. I feel supported and not compressed.”
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | unpleasant | excellent | excellent |
| Average (130-230 lbs) | good | excellent | excellent |
| Heavy (over 230 lbs) | good | excellent | good |
| Body Weight: Light (under 130 lbs) | |
|---|---|
| Side Sleeper | unpleasant |

| Stomach Sleeper | excellent |

| Body Weight: Heavy (over 230 lbs) | |

| Back Sleeper | excellent |
| Stomach Sleeper | good |
Our Expert Opinion
The Saatva Classic is more than just a match for stomach sleepers. It’s the bed I sleep on every night — and as a stomach sleeper myself, it’s supportive enough for the hips without feeling too firm on the chest. It’s also a well-rounded option for folks who want a luxury mattress that delivers on its promise and more.
Aside from its support, the best part about the Saatva is its responsiveness. It’s super easy to move around on this mattress, and its sturdy perimeter ensures you don’t slide off. Unfortunately, it has some embarrassingly high motion transfer, which could deter sleepers who share the bed.
Choose the Saatva if …
- You need time to find out if you like your mattress. Saatva offers a 365-night trial with every one of its mattresses. That means you get a full year to try out the bed. You can return it for a full refund, minus a $99 removal fee.
- There are mobility concerns for either you or your partner. The Saatva’s lack of sinkage and excellent edge support will help older folks and caretakers transfer in and out of bed without incident. It’s also a bonus for combination sleepers and sexually active couples who need a responsive mattress.
Keep looking if …
- A partner’s or pet’s movements keep you awake. The Saatva Classic earned its lowest score in motion isolation. You’ll feel every twitch and shift from your partner’s side of the bed. Fellow light sleepers, I recommend the WinkBed instead.
- You’re on a budget. At nearly $2,000 for a queen, the Saatva isn’t exactly the most affordable. However, considering its construction, performance, and customer service perks, I think it’s definitely worth it.
For more information about this bed, read our full Saatva mattress review.
Brooklyn Bedding Signature Hybrid – Best Firm Mattress for Back Sleepers
The Brooklyn Bedding Signature Hybrid mattress combines a foam comfort layer and sturdy coils. This combination of materials makes it bouncy and easy to move around on. It comes in three firmness levels, and we recommend the Medium model for most back sleepers. It’s a great choice for shoppers who are looking for a new mattress on a budget. For more information, check out our video review.
What our tester says:
“Given that the Signature Hybrid has some excellent bounce, I’d highly recommend this mattress for combination sleepers who often change positions multiple times throughout the night. I also think the Signature Hybrid could be a great fit for couples. You shouldn’t be overly disturbed by a restless partner on this bed, and it has nice, firm edge support.” – Nichole Mondshein, lead reviewer and staff writer
Why It’s the Best Firm Mattress for Back Sleepers
- The Brooklyn Bedding Signature Hybrid comes in multiple firmness levels, including Firm, which should feel closer to 7.5 out of 10 on our scale.
- Despite its firmer feel, this mattress earned a perfect 5-star rating for back-sleeping pressure relief.
- It earned a 4 out of 5 for responsiveness and a 4.7 out of 5 for motion isolation, thanks to its balanced hybrid construction.
How Did It Perform During Testing?
Motion Isolation: 4.7/5
This hybrid offers some excellent motion absorption despite the springs in its construction.
Cooling: 3.5/5
The Signature Hybrid felt just okay during our temperature regulation test, but some hot sleepers may prefer a more actively cooling bed.
Response: 4/5
The Signature Hybrid’s soft cover layer might make it challenging for some combination sleepers to move around, but you should still get some bounce from the coils.
Edge Support: 3.4/5
We noticed quite a bit of sinkage during our weighted edge support test, but the perimeter does help you “bounce” to your feet.
Pressure Relief: 4.8/5
The soft cushioning of the Signature Hybrid makes it a good option for back and side sleepers.
Firmness: 6.5/10
The Brooklyn Bedding Signature Hybrid falls right at the industry standard of medium-firm.
Tester Notes
“I really like this mattress for back sleeping,” said expert mattress tester Riley Otis. “My body felt evenly supported from head to toe, and my spine stayed in a nice, neutral position. I also noticed some solid contouring through my lower back, which helped fill in that space and keep everything properly supported. If lumbar support is a priority, this one delivers.”

Our Expert Opinion
Sometimes I say back sleepers are the easiest to please, but that doesn’t mean they can’t be picky when it comes to a firmer mattress. Thankfully, Brooklyn Bedding’s Signature Hybrid comes in a Firm model, though we loved the Medium for back sleepers. This praise should carry over to the next level.
Aside from pressure relief and support, this bed offers a good mix of both responsiveness and motion absorption to appeal to co-sleepers. However, its edge support isn’t the strongest for a hybrid.
Choose the Signature Hybrid if …
- You’re a back or side sleeper. Both of these positions were a hit with our pressure relief testers. Just note that the firmer version could pose a problem for lightweight side sleepers with sensitive hips or shoulders.
- You share the bed with a partner. While we thought this bed had a good amount of bounce, its thick comfort layers also work to stifle motion before it can travel across the surface.
Keep looking if …
- You frequently sit on the edge of your mattress. While the perimeter feels bouncy, we felt the pillow top compressing under our weight. This may differ in the firmer model of the mattress, but keep it in mind if you use your bed like a second chair.
- Active cooling is a must-have for your mattress. This bed never heated up throughout testing, but it didn’t feel cool to the touch either. For a mattress that stays cool and feels cool, check out the Bear Original.

Nolah Evolution – Best Firm Mattress for Pressure Relief
The Nolah Evolution’s hybrid construction offers the cushioning of memory foam with the responsiveness of coils. The Luxury Firm model is a good option for side and back sleepers due to its medium-firm feel, though there are Plush and Firm versions as well. Those who share a bed may also appreciate its low motion transfer, so you won’t be disturbed by a partner’s movements and its solid edge support to allow you to maximize surface area. For more information, check out our video review.
What our tester says:
“I laid down to rest on this mattress on my back — my primary sleep position. I felt comfortable, but also appreciated the cozy, plush top of the bed. After some time lying on my back, I switched over to my side. I didn’t find this position quite as comfortable, as I did feel some slight pressure buildup in my shoulder.” – Amelia Jerden, senior staff writer
Why It’s the Best Firm Mattress for Pressure Relief
- Even the Luxury Firm model of this bed skews firmer than expected at 7 out of 10 on our scale, but there is a Firm option, should you so choose it.
- Our pressure relief testers gave the Nolah Evolution a 4.3 for both back and side sleeping.
- This bed earned a rare perfect rating for motion isolation, as well as a 4 or higher in every category.
How Did It Perform During Testing?
Motion Isolation: 5/5
Our tester noticed no movement during our ripple test, resulting in a perfect score for motion isolation.
Cooling: 4.5/5
The Nolah Evolution showed above-average cooling capabilities.
Response: 4/5
Our tester found it fairly easy to roll around on the Nolah Evolution.
Edge Support: 4.6/5
The Nolah Evolution had a strong perimeter, earning a high edge support test.
Pressure Relief: 4.3/5
The bed was good at relieving pressure, though some of our testers wanted more sinkage.
Firmness: 7/10
The springs in the construction made for a slightly firmer feel.
Dr. Tedesco’s Notes
Dr. Joe Tedesco praised the “weightlessness” he found while resting on the Nolah Evolution mattress, which came from even pressure disbursement while resting on his back and side. But back sleeping was his favorite: “I’m not feeling any significant pressure buildup on my back,” he said. “My feet and ankles and hips and knees are aligned; my pelvis is relaxed and I don’t feel any anterior tilt.”
Staff writer and certified sleep coach Sosha Lewis sleeps on a Nolah Evolution and corroborated this: “My personal favorite aspect is the pressure relief! As a middle-aged CrossFitter with a janky hip, this bed eases so much of my pain.”
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | good | excellent | excellent |

Our Expert Opinion
Picking a firm mattress doesn’t mean sacrificing pressure relief. Maybe you’re a back or side sleeper who likes or needs a firm mattress, as both of these positions require some relief on the hips, shoulders, or lower back. The Nolah Evolution is here to offer you the best of both worlds, and it even comes in a Firm model, though the Luxury Firm may fit the bill for most firm mattress fans.
Back and side sleepers will appreciate the Evolution’s contouring layers up top, while its coils will work to keep their spines aligned. Since its performance was above-average across the board, the main gripe shoppers may have is its higher price tag.
Choose the Nolah Evolution if …
- You sleep on your side or back. As mentioned, these were the favorite positions of our testers, regardless of size. You may notice less contouring on the Firm model of the mattress, but there will be plenty on the Luxury Firm to cushion the hips, shoulders, and lower back.
- Bed that completely stifles motion is at the top of your list. Our motion isolation tests for the Nolah Evolution ended with exceptional results. You likely won’t feel your partner’s movements at all on this mattress, maybe only a slight ripple if they get out of bed (or cannonball into it).
Keep looking if …
- You like a super-bouncy firm bed. Because of the nature of this bed’s pillow top, we found a bit more resistance when we moved around on the surface.
- There are budgetary constraints. The main drawback to this bed is that as a luxury mattress, the Evolution costs a pretty penny, almost $1,600 for a queen. For an affordable option, consider the DreamCloud.

Bear Original – Best Firm Memory Foam Mattress
Even though it’s made entirely of foam, the Bear has a firm, supportive feel that should be sturdy enough for back sleepers and stomach sleepers alike. Additionally, combination sleepers should be able to easily move around on its surface. You can also pay extra for a Celliant cover that may help with cooling and muscle recovery. Learn more in our video review.
What our tester says:
“I found the double poly foam construction produced a firm, supportive feel. Though you’re likely to sink into its top layer of memory foam, this sinkage is somewhat curbed by the taut poly foam transition layer. This means most folks are going to be positioned more “on top” of the structure than “in” it.” – Nichole Mondshein, lead reviewer and mattress tester
Why It’s the Best Firm Foam Mattress
- The all-foam Bear Original mattress comes in at 7 out of 10 on our firmness scale, skewing just upwards of medium-firm.
- This bed excels in many areas not often associated with foam beds, like cooling, edge support, and responsiveness.
- Of course, like most foam mattresses, the Bear Original also has exceptional motion isolation, earning a 4.7-out-of-5 rating.
How Did It Perform During Testing?
Motion Isolation: 4.7/5
Like many other memory foam models, the Bear Original has excellent motion isolation.
Cooling: 4.5/5
Our testers found that the surface of the Bear Original stayed cool and comfortable.
Response: 4/5
The Bear Original is surprisingly easy to move around on despite not having any springs in it.
Edge Support: 4.2/5
Sleepers should be able to lie along the perimeter of the mattress without feeling unsteady or falling off.
Pressure Relief: 3.2/5
The Bear Original excels at relieving pressure for back sleepers but might be too firm for some side sleepers.
Firmness: 7/10
The Bear Original is a touch firmer than the industry standard of medium-firm (6.5 out of 10).
Dr. Tedesco’s Notes
“I love the support of this mattress and think it would be great for people with back pain,” said Dr. Tedesco after giving the Bear Original a whirl. “On my side, the heaviest parts of the body feel very supported, and there’s no pressure buildup,” he added. “When I rest on my back, I sink in a bit more, but I can feel the firmness of this mattress pushing me back up.”
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | unpleasant | excellent | excellent |
| Average (130-230 lbs) | good | excellent | excellent |

Our Expert Opinion
Most people associate the best memory foam mattresses with cushy softness, but firm mattress fans might be surprised to learn that there are plenty of firm foam beds out there. The Bear Original is one such bed — dare we call it a rare gem? It came in at about a 7 out of 10 on our mattress firmness scale, firmer than many other all-foam beds on the market.
Choose the Bear Original if …
- You run hot. The standard cover of this mattress is already pretty cool, but you can upgrade to the brand’s specialized Celliant cover for an extra fee. Some clinical trials show that this material absorbs the energy in your body and then redirects it back to you to assist with blood flow and recovery, also helping to reduce excess body heat.
- You share the mattress. With its above-average edge support and motion isolation, plus its decent responsiveness, the Bear Original has many qualities that appeal to couples.
Keep looking if …
- You sleep on your side. The Bear Original is too firm for these sleepers. Only our average-weight tester got comfortable in this position, and even then thought it was too firm for their tastes.
- You weigh over 230 pounds. These sleepers will likely sink straight through the mattress and “bottom out” on the uncomfortable support layers.

Titan Plus Core – Best Extra-Firm Mattress
The Titan Plus mattress is a durable mattress made with heavy sleepers in mind. It’s firm and features heavy-duty coils and Titanflex foam that makes it bouncy and easy to move around on. We think that heavy back sleepers and stomach sleepers should be especially comfortable. For more information on the Titan Plus, check out our video review.
What our tester says:
“I think the Titan Plus lives up to its name as a good mattress for heavier sleepers. It will offer them the deep compression support and durability they need.” – Nichole Mondshein, lead reviewer and staff writer
Why It’s the Best Extra-Firm Mattress
- We rated the Titan Plus Core at 7.5 out of 10 on our firmness scale, an extra-firm feel that’s designed to support sleepers over 230 pounds.
- Stomach sleepers of any size should enjoy this bed’s ultra-firm support.
- This bed scored 4s and above in all our testing categories, including a perfect responsiveness score.
How Did It Perform During Testing?
Motion Isolation: 4.3/5
Our testers were impressed by how the Core dampened motion and prevented it from rippling across the bed’s surface.
Cooling: 4/5
The innerspring coils and GlacioTex cooling cover give this mattress a temperature-regulating edge.
Response: 5/5
The sturdy innerspring coils make the surface of this mattress highly responsive and easy to move around on.
Edge Support: 4/5
We found minimal sinkage near the perimeter of the Titan, meaning it is a good pick for sleepers who rest on the edge.
Pressure Relief: 4.3/5
While most sleepers should experience solid pressure relief, those with sensitive joints may experience some buildup.
Firmness: 7.5/10
The Titan Plus Core’s heavy-duty construction is quite firm compared to most mattresses.
Dr. Tedesco’s Notes
“A larger person who needs support will probably do better on their back on the Titan Plus Core,” Dr. Joe Tedesco suggested after trying out the mattress himself. This was echoed by our heavyweight tester, who noticed too much pressure buildup on his side. “Though there’s not much cushioning, this mattress is doing what it’s supposed to do, orthopedically,” Dr. Tedesco added.
How Does It Feel in Different Sleeping Positions?

Our Expert Opinion
The Titan Plus Core has a majestic name that echoes its purpose: to supply industrial support for folks who need it, like those with bigger bodies or those who weigh over 230 pounds. Most of these folks need a firmer mattress anyway; their weight tends to have them sinking further into softer beds, leading to a misaligned spine or overall discomfort. And at 7.5 out of 10, this bed is decidedly ultra-firm.
This is a responsive hybrid that still provides excellent pressure relief and motion absorption in its thick upper layers. However, its extra-firm feel could pose a problem for some lightweight sleepers and arthritis patients — but it’s a great pick for stomach sleepers of all sizes.
Choose the Titan Plus Core if …
- You sleep on your stomach, regardless of size. The Titan Plus Core will keep your hips elevated and ensure they don’t fall out of alignment. This ensures you don’t get lower back pain in this position.
- You share the bed with a partner. This mattress has some surprisingly good motion isolation for how bouncy it is. It’ll likely be a good mattress for light sleepers and sexually active couples who like a firmer feel.
Keep looking if …
- You have sensitive joints. Folks who have sensitive hips and shoulders, especially arthritis, may not agree with the Titan’s extra-firm feel. For these sleepers, I’d suggest the Nolah Evolution.
- You weigh under 130 pounds. Though our lightweight tester found some comfort side-sleeping on the Titan Plus Core, she noted this wasn’t for everyone. This bed will likely feel even firmer for these folks, something to consider if you’re not-quite sold on an extra-firm bed.

Birch Natural – Best Organic Firm Mattress
The Birch Natural mattress is an all-natural bed from Helix Sleep that’s comfortable, supportive, and eco-friendly. Its combination of natural Talalay latex and individually wrapped coils makes it easy to move around on. I think this bed is a great choice for shoppers who are looking for durable mattress with organic materials. For more information, check out our video review.
What our tester says:
“I’d say the Birch is a fantastic pick for sleepers with back pain (especially if they sleep on their backs or stomachs). While lying on it, I felt the Birch’s springs and bouncy latex kept my spine in a pleasantly lifted position.” – Madison Schaper, former Staff Writer
Why It’s the Best Organic Firm Mattress
- The Birch Natural came in at a 7 out of 10 on our mattress firmness scale —a bit firmer than the industry standard for medium-firm (6.5 out of 10)
- This mattress features organic latex as its primary component, along with cotton and wool for an eco-conscious, natural construction.
- The Birch also earned several 4-out-of-5 ratings, as well as a perfect score for responsiveness.
How Did It Perform During Testing?
Motion Isolation: 4/5
Despite its springy feel, the Birch Natural does a surprisingly good job of dampening motion.
Cooling: 4/5
Hot sleepers shouldn’t have to worry about overheating on the Birch Natural mattress.
Response: 5/5
The combination of bouncy latex and responsive innerspring coils make this mattress easy to move around on.
Edge Support: 4/5
Sleepers who gravitate toward the edge of the bed should appreciate the Birch’s reinforced perimeter.
Pressure Relief: 4/5
While the Birch provides solid pressure relief for various types of sleepers, it is ideal for back sleepers.
Firmness: 7/10
The Birch Natural is slightly firmer than the industry standard of medium-firm (6.5 out of 10).
Dr. Tedesco’s Notes
Contrary to our testers’ opinions, Dr. Joe Tedesco thought the Birch Natural was “definitely more comfortable on the side.” He explained, “The springiness and softness up top help me feel much more relaxed on my side. It’s more supportive, and there’s less pressure on my feet, knees, or hips.” He also believed it could work for folks experiencing hip or shoulder pain, or side sleepers wanting a supportive yet comfortable mattress for scoliosis.
How Does It Feel in Different Sleeping Positions?
| Body Weight | Side | Back | Stomach |
|---|---|---|---|
| Light (under 130 lbs) | good | excellent | good |
| Average (130-230 lbs) | good | excellent | excellent |
| Heavy (over 230 lbs) | unpleasant | good | good |

Our Expert Opinion
Environmentally conscious mattress shoppers may come across a lot of latex mattresses in their online search. Fortunately, organic latex can add to a bed’s firmness, while also providing a uniquely buoyant feel. The Birch Natural is one such latex hybrid.
Aside from plenty of bounce, this bed provides a good bit of pressure relief, cooling, and motion absorption. It’s a good jack-of-all-trades pick, aside from its higher price. Certified organic and natural components often increase a bed’s price, but for the peace of mind, it may be worth it.
Choose the Birch if …
- You like to feel “on top” of your mattress. The combination of latex and coils in the Birch makes you feel buoyed on the bed’s surface. You’ll never feel “stuck” when you try to move around on this bed.
- You share the bed with a partner. Latex often wobbles and transfers motion, rather than stifling it, which makes the Birch a rare find. Our testers noticed many big movements were absorbed before they could travel across the surface, so you can rest undisturbed throughout the night.
Keep looking if …
- A bouncy bed is not what you have in mind.. The unique feel of latex isn’t for everyone. It’s more than just springy coils — it’s buoyant and pillowy, yet not as soft and contouring as memory foam. If you’ve never tried a latex bed, take full advantage of the brand’s sleep trial to ensure it’s right for you.
- You’re on a budget. All-natural mattresses in general are always going to be a bit more expensive than your average joe. A queen-size Birch Natural costs $1,500, which is pretty good for latex, but not exactly the cheapest on our list. If you want a bed for a fraction of that price, check out the DreamCloud.

Latest Updates: In August of 2026, we updated this page to reflect both re-testing of these mattresses and an overhaul to our format. Our panel remains largely unchanged, but you’ll see more input from our team of experts, including our medical product tester, Dr. Joe Tedesco (DPT).
Other Mattresses I Considered
Still looking for more options? Here are some other firm mattresses we’ve reviewed that didn’t quite make the cut:
Purple Mattress
This mattress has a 7 out of 10 firmness score from our testing lab, so it’s just a bit firmer than true medium-firm (6.5 out of 10) and should widely appeal to side and back sleepers who like a firmer feel. While it offers impressive results for light and average-weight sleepers, those falling on the heavier side likely won’t receive the same amount of support.
Plank Firm
The precursor to the Plank Firm Luxe, the original Plank Firm is a flippable, all-foam mattress that boasts the same dual-sided firmness. We’d say it feels even firmer than the Luxe, best for stomach sleepers and those over 230 pounds. Unfortunately, this firmness also comes with many downsides, and its lack of coils may limit its ability to support certain sleepers. Therefore, we opted for the Luxe.
How We Tested the Best Firm Mattresses
Shopping for a mattress can be daunting. Thankfully, our expert testers compiled some of the most important factors you may want to consider based on your personal preferences. No bed is one-size-fits-all, especially when it comes to a firm mattress.
Key Testing Categories for Firm Beds
Firmness Rating
At Sleepopolis, we measure mattress firmness using the mattress firmness scale. The scale ranges from 1 to 10, with 1 being the softest mattress ever and 10 being the firmest mattress ever. The industry standard for medium-firm is 6.5 out of 10. We typically see mattresses in this category, since this firmness level can appeal to a wide range of sleep positions and body types. Anything lower than 6.5, we consider soft, and anything higher than 6.5 is firm.
As for testing a bed’s firmness, our lead mattress reviewer will lie down on the bed and give it a numbered score on the firmness scale. They then have several colleagues do the same thing and come up with an average of everyone’s scores. That’s the final number you see for each mattress’s firmness.
When we take all the beds we’ve ever tested into account, the average firmness rating is about 6.7 out of 10. The mattresses you see below all scored above this number (and some well above), solidifying them as firmer than average.
*While many of the beds we’ve tested come in multiple firmness options, the numbers below are for the mid-range model. I’ve marked these for your benefit. Many already surpass the firm threshold, but for those that don’t, we recommend the firmest model.
How the Best Firm Mattresses Rated on Our Scale
| Mattress | Firmness Rating |
| Plank Firm Luxe | 7, 7.5 |
| Helix Dawn | 7 |
| DreamCloud Memory Foam | 7 |
| WinkBed* | 6.5 |
| Saatva* | 7.5 |
| Brooklyn Bedding Signature Hybrid* | 6.5 |
| Nolah Evolution* | 7 |
| Bear Original | 7 |
| Titan Plus Core | 7.5 |
| Birch Natural | 7 |
Responsiveness
Firm beds usually have a lot of response, which is a close cousin to bounce. It refers to when a mattress snaps back into place when you press down on it, which is what firm beds excel at.
To rate how responsive a mattress feels, our testers get on the bed ourselves and move around, sometimes jumping on it to gauge how responsive the surface is.
The average responsiveness score for all beds we’ve tested is 4 out of 5. Ideally, these firm beds should score at or above this number, as many do. However, other aspects of a bed’s construction (like being made entirely of foam, for example), can bring the responsiveness down. It’s unlikely that you’ll feel “stuck” in any of these beds.
How the Best Firm Mattresses Scored in Responsiveness
| Mattress | Responsiveness Score |
| Plank Firm Luxe | 4.8 |
| Helix Dawn | 5 |
| DreamCloud Memory Foam | 4.5 |
| WinkBed | 3 |
| Saatva | 5 |
| Brooklyn Bedding Signature Hybrid | 4 |
| Nolah Evolution | 4 |
| Bear Original | 4 |
| Titan Plus Core | 5 |
| Birch Natural | 5 |
Support
Regardless of a mattress’s firmness, you’ll want to make sure it provides enough support to keep your spine in neutral alignment. And by that, I mean that your hips and shoulders should evenly line up with each other, with no excessive sinkage that will throw off your posture.
At Sleepopolis, we test support by judging how we feel lying down on the bed. Sometimes we’ll have a friend observe to see if our spines are straight.
Also under the umbrella of overall support is edge support. A strong perimeter ensures you can sit or lie down at the far reaches of the mattress. It’s also a marker for durability, a sign that a mattress is more likely to hold its shape despite repeated use. Firm beds also tend to score higher in this area, as they offer greater rigidity.
Our average edge support score comes out to 4 out of 5. While not all of these mattresses scored higher than this number, it’s a good metric to be aware of. It certainly doesn’t mean the mattress is unsupportive or poor-quality. All beds we recommend should last you well into their 10-year lifespan, if not more.
How the Best Firm Mattresses Scored in Edge Support
| Mattress | Edge Support Score |
| Plank Firm Luxe | 3.3 |
| Helix Dawn | 4 |
| DreamCloud Memory Foam | 4.2 |
| WinkBed | 4.4 |
| Saatva | 4.8 |
| Brooklyn Bedding Signature Hybrid | 3.4 |
| Nolah Evolution | 4.6 |
| Bear Original | 4.2 |
| Titan Plus Core | 4 |
| Birch Natural | 4 |
Other Tests
There’s more to a firm mattress than just feeling firm and providing support. Depending on what kind of sleeper you are and your individual needs, certain performance aspects could be a must-have in your mattress. Let’s go over some other categories that we test and review, so you can make an informed decision about your new mattress.
Pressure relief is one important consideration when choosing a mattress. Firm mattresses tend to offer a bit less pressure relief than softer beds, but that doesn’t mean you need to sacrifice appropriate relief. If pressure relief is a priority for you, we’d recommend looking for a firm bed that includes a few memory foam layers that offer some body contouring.
Motion transfer is a measure of the amount of motion that travels from one side of the mattress to the other. Most sleepers who share a bed with a partner or pet prefer a bed with low motion transfer, or good motion isolation. Firm mattresses usually don’t isolate motion as well as softer beds. However, firm beds that contain memory foam are good options for motion absorption.
Finally, shipping, sleep trials, and warranties all come with the purchase of a new mattress, and you might overlook them in your haste, but they can be beneficial in narrowing down your search. Generous sleep trials can ensure you have plenty of time to decide if a bed is right for you, while lengthy warranties could signal manufacturer’s trust in the bed’s quality.
