Top Firm Mattress Picks Explained

Read on for more details on all the mattresses featured above. I’ll continue to update this list as I test and review new mattresses, so don’t be surprised if your top picks get knocked out of the top spots! If you’re in a rush, I have a few quick facts about each mattress in a handy chart below.

Editor’s Pick – Saatva

One of the most popular innerspring mattresses on the market, the Saatva employs individually wrapped coils and sturdy steel coils to offer the firm support and bounce of a classic innerspring mattress. The Saatva is offered in three different firmness options: Plush Soft, Luxury Firm, and Firm. I’ve personally tested the Luxury Firm model and found it to be really supportive for back and stomach sleepers (but a bit too firm for side sleepers). This could be a great match for strict back or stomach sleepers, as well as for combo sleepers, who move between these positions. If you’d prefer an even firmer comfort level, you can opt for the Firm model.

No matter which model you choose, the bounciness of the Saatva’s springs means you’re likely to sleep more on top of the bed than “in” it, which is nice for combination sleepers who need ease of movement. Additionally, each model of this mattress is sturdy and durable. The Saatva is also well-suited to couples who are looking for a mattress that’s up to the task of supporting two bodies over the long-term.

The Saatva comes with a 180-night sleep trial and 15-year warranty.

Best Flippable Mattress – Brooklyn Bedding Plank

Get two firm mattresses for the price of one with the Plank, a flippable mattress from Brooklyn Bedding that has one firm side and one extra firm side (and I do mean extra firm). The extra firm side features the strongest support of any mattress on this list, so it will appeal to folks who think a regular firm mattress is child’s play. It should also appeal to stomach sleepers, who need plenty of support to keep their hips elevated and their spines in a neutral alignment. For similar reasons, this bed might be a good choice for back sleepers who like a firm feel.

Because the Brooklyn Bedding Plank is so firm, you might be surprised to learn that it’s an all-foam mattress. But the firm high-density foam base offers even more support than some innerspring beds. The Plank’s cover comes with an optional cooling panel made of Phase Change Material that helps dissipate body heat. This could be a good add-on if you’re a stomach sleeper who wants to sleep cool. Keep in mind, it will add an additional cost to your purchase.

The Plank comes with a 120-night sleep trial and 10-year warranty.

Best Firm Mattress for Stomach Sleepers – Helix Dawn

The Helix Dawn mattress is my top pick if you’re a strict stomach sleeper looking for a firm mattress. Due to it’s firm top layer of Helix Dynamic Foam, you’ll feel like you’re “on-top” of the bed, keeping your hips from sinking in, and aligning your spine and shoulders. But, the Helix Dawn still offers pressure relief at your hips and shoulders, so you don’t have to sacrifice the “hugging” feel of a mattress that so many of us love.

Helix has a line of six mattresses and the Dawn is their firmest option. It also is available in a luxury version called the Helix Dawn Luxe. The Dawn is supported by wrapped pocketed coils to give sleepers bounce and lift. This is also helpful in supporting your body weight and allowing you to move and roll around, a great option for those who sleep with a partner or toss and turn throughout the night.

The Dawn comes with a 100-night sleep trial and 10-year warranty.

Best Affordable Firm Mattress – Casper

The Casper mattress is a great firm option for sleepers on a budget. This all-foam bed is quite affordable, which makes it a nice option for shoppers looking for a high-quality, durable mattress that won’t break the bank.

Something especially nice about the Casper is that it features Zoned Support. That means this mattress is firmer at the hips and lower back to offer some extra support, but softer around the shoulders to offer some pressure relief. The result is a firm-but-balanced feel that back and combination sleepers should really like.

If you’re looking for a firm budget mattress, I’d highly recommend checking out the Casper. Considering its supportive nature and durable materials, this bed is priced extremely well.

The Casper comes with a 100-night sleep trial and 10-year warranty.

Best Cooling Mattress – WinkBed

The WinkBed is a popular hybrid option for those who prefer a firmer bed. It has several features meant to keep you sleeping cool. First up is a breathable Tencel cover that allows for airflow into the mattress, which you can learn more about in our overview of the material, Tencel – What It Is. Then there’s the gel-infused top layer, which helps draw heat away from sleeping bodies. And finally, the pocketed coil support layer allows for more airflow. So if you’re prone to sleeping hot, definitely give the WinkBeds a look!

The mattress comes in three firmness levels, as well as a Plus model for heavy folks, so its feel will vary a bit depending on the model in question. The firm and medium-firm mattress models should both appeal to those who enjoy a firmer feel. Each WinkBed model also includes a Euro pillow top to offer a little  pressure point relief (without sacrificing a firm feel).

The WinkBed comes with a 120-night sleep trial and lifetime warranty.

Best Firm Mattress for Side Sleepers – Puffy

Side sleepers often need a softer mattress that provides some pressure relief. But if you’re a side sleeper on the hunt for a firm bed, the Puffy could do the trick! This bed-in-a-box mattress should feel nice and firm to side sleepers. While I consider the Puffy mattress medium-firm, it should feel firmer to those who spend the entire night on their sides.

But, its “Gel Cloud” comfort layer makes the bed softer than most firm mattresses, so it will offer enough pressure relief for side sleepers as well.  “Gel Cloud” sleeps cooler and helps alleviate aches and pains by providing great pressure relief.

The Puffy Mattress is a great option for lightweight to average weight sleepers, making it a great option for kids.  The Puffy Mattress is perfect for those who don’t like to sink into the bed too much, but are light enough for their shoulders and hips not to jam into the mattress.

The Puffy comes with a 101-night sleep trial and lifetime warranty.

Learn more in my full Puffy mattress review.

Best Firm Mattress for Back Sleepers – GhostBed

Firm mattresses are often a good match for back sleepers, but the GhostBed stands out even amongst a sea of other firm models — especially for those back sleepers who prefer an all-foam feel. Its comfort layer is made from 1.5 inches of aerated latex, which offers some nice bounce and is very cooling. Latex mattresses are often great picks for sleepers who like a firm feel because of their naturally supportive, durable feel.

The GhostBed comes in at a 7 out of 10 on the mattress firmness scale. For reference, a medium-firm mattress is about a 6.5 out of 10 on the scale. So if you’re a back sleeper looking for a firm bed that also offers a bit of gentle pressure relief, the GhostBed is a great choice for you.

The GhostBed isn’t only a great option for back sleepers; I also really like it for hot sleepers. All GhostBeds are known for sleeping cool, and the Original is no exception. The combination of cooling materials used in this mattress really helps prevent it from trapping body heat.

The GhostBed comes with a 101-night sleep trial and 20-year warranty.

Best Firm Memory Foam Mattress – Bear

The Bear mattress is a great option for those who prefer a firmer feel but love the body contouring properties of memory foam. The Bear’s comfort layer is made with cooling graphite gel foam, which doesn’t trap heat, so you should be feeling nice and cool.. Below that you’ll find a transition layer of responsive foam, which adds a bit of bounce. The Bear’s base is made from high-density poly foam which gives it some nice firm support.

I also think the Bear could be a good option for athletes. It’s cover is made of Celliant, a material that some studies suggest helps speed up athletic recovery. Athletes also need a combination of pressure relief and support, and the Bear offers just that.

The Bear comes with a 100-night sleep trial and 10-year warranty.

Learn more in the full Bear mattress review.

Best Firm Mattress for Couples – Layla Hybrid

For couples that like a firm mattress, I’d highly recommend the Layla Hybrid. This flippable mattress is built with soft and gentle top layers that provide a great amount of pressure relief, but is grounded in a tall section of ultra-sturdy pocketed coils.

The resulting feel is balanced, hedging slightly on the firmer side of things. But what’s really great about this bed is that couples (thanks to the flippable design) can switch between either a “Soft” or “Firm” side depending on their needs. Thankfully, both configurations feature top layers of memory foam, a plush material that actively works to isolate motion across the structure, which could be a big plus for couples.

The Layla Hybrid comes with a 120-night sleep trial and 10-year warranty.

Learn more in my full Layla Hybrid mattress review.

Best Organic Mattress – Birch

This hybrid bed-in-a-box should appeal to sleepers who like a firm mattress and are committed to going green. The mattress is composed entirely of eco-friendly materials, including an organic cotton cover, a comfort layer made of natural wool, and a section of all-natural Talalay latex. All of these layers are supported by pocketed coils. Birch also offers optional organic mattress toppers with these beds in case you prefer a softer feel.

The Birch features a firm feel, strong support, and fantastic bounce thanks to its Talalay latex and coil layers. This mattress should be a great fit for back and stomach sleepers, who need plenty of support to keep their spines in neutral alignment and prevent backaches and pains. And because it’s easy to move around on this bouncy mattress, it might also work well for combination sleepers who switch between their backs and stomachs.

The Birch comes with a 100-night sleep trial and 25-year warranty.

How to Choose a Firm Mattress

Now that you know more about a few of the best firm mattresses out there, let’s talk a little bit about how to choose the right one for you! Keep in mind that firmness, aka the initial feel of a mattress when you lie down, is not the same as support, aka how well a mattress keeps your spine aligned. First up, let’s go over what to look for when choosing a firm mattress.

Mattress Materials

Certain types of mattresses tend to be firmer than others. If you’re looking for a firm mattress I’d recommend opting for an innerspring, hybrid, or latex mattress. Take a look below to learn more about the different types of firm mattresses.

• Innerspring mattresses – Innerspring mattresses are made of steel coils and topped with thin layers of foam. They normally have a firm, bouncy feel, and most sleepers looking for a firm mattress will likely find an innerspring bed that meets their needs. Take a look at our top picks for best innerspring mattresses.
• Latex mattresses – Latex mattresses use latex foams in their construction. These materials are naturally durable, cooling, and bouncy, and can have very firm, supportive feels. Latex mattresses often combine latex and steel coil support systems. If this sounds like something you’d be interested in, read through our best latex mattress page!
• Hybrid mattresses – Hybrid mattresses combine top comfort layers with innerspring support coils. They can vary widely in feel, but there are plenty of great firm options available for sleepers looking for a firm bed. Learn more about hybrid mattresses in our round-up of the best hybrid mattresses.
• Foam Mattresses – It is possible to find a firm foam mattress, but these options may not be as durable or supportive as other mattress types because they use foam rather than coil support cores. If these types of mattress are something you’d be interested in, I recommend taking a look at our best memory foam mattress page.

The Best Mattress Firmness for your Body Weight

Next, let’s take a look at what a firm mattress feels like for people with different weights. Depending on your body type, a firm mattress may or may not be the best fit for you.

Light Sleepers

Lighter sleepers are likely to find firm mattresses firmer than average weight sleepers because they won’t sink as far through these bed’s top layers. In general, light stomach sleepers should fare well on almost any firm mattress because stomach sleepers don’t need much pressure relief. But lightweight back and side sleepers might want to stick to a more medium-firm mattress if they’re looking for a firm feel. These beds will likely feel firm to lighter folks, and will offer them a little more pressure relief in these sleeping positions.

Average Weight Sleepers

Average weight people will likely experience mattresses as they’re advertised. That means a mattress advertised as firm or described as firm in reviews will likely feel firm to them. In general, a firm mattress is a great fit for any average sleepers who prefer this feel. But, if you’re a side sleeper, I might recommend opting for something a bit softer to ensure you get enough pressure relief at your hips and shoulders.

Heavy Sleepers

Firm mattresses are some of the best options for heavy people. These sleepers will likely find many mattresses a bit softer than the average sleeper, which means some firm mattresses may feel more medium-firm to these folks. A medium firmness level is considered universally comfortable, so heavy sleepers looking for this feel should opt for a firm bed. If you’re a heavy sleeper looking for a truly firm feel, a mattress designed specifically for heavy people could be a good fit. Check out our top picks for the best mattress for heavy people for more options.

Pressure Relief

Pressure relief is another 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, I’d recommend looking for a bed that includes a few firm memory foam layers that offer some body-contouring. This will provide a bit of pressure relief, but allow for a firm feel.

Motion Transfer

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, but you can still find a firm mattress with decent motion isolation. Hybrid mattresses with memory foam top layers, or firm all-foam mattresses are good options for sleepers looking for a bed that isolates motion well.

Price

The last factor you’ll want to consider when buying a new firm mattress is price! A bed’s price will vary depending on the quality of the materials it’s made with. Generally, you can find certain foam and hybrid mattresses at budget prices, while many latex and innerspring mattresses can be pricier.

A new mattress is a big investment, but you can score good deals by shopping online, shopping during sales, and using our mattress coupons. Check out our best cheap mattresses guide for more tips on how to save money on your new bed!

Who is a Firm Mattress Best For?

Firm mattresses are especially helpful for sleepers who need firm support to keep their spines straight overnight. In the list below, I’ll describe who these sleepers are and why firm support is best for them. And check out our Mattress Firmness Guide for more information on selecting the feel and firmness that’s most appropriate for your body type and preferred sleeping position.

• Back sleepers can benefit from firm support because it will help them keep their spine neutrally aligned (read: straight) overnight. This is especially important for back sleepers who struggle with any kind of back pain.
• Stomach Sleepers need firm support because there are very few gaps between their bodies and their mattresses when they sleep. This means they really need a bed that won’t let their hips sink into the mattress. Sinking hips creates an arch in the back that leads to pain over time.
• Heavy people (over 250 lbs) tend to do best on firm mattresses because they’re a little more durable, and won’t sag as soon as a softer mattress. I’d also encourage these sleepers to opt for a firmer model than they think they need because mattresses are built with people between 130-250 lbs in mind. This means most beds will actually feel softer to heavier people than they do to other sleepers. Beds specifically designed for heavy people are more likely to feel as firm to these sleepers as advertised.
• People with back pain often do best on firm mattresses because they need to be extra conscious of their sleep posture. Keeping your spine straight overnight can help alleviate and prevent a lot of lower back pain over time. If this is something you find yourself struggling with, I also recommend checking out our best mattresses for back pain roundup!

Who Should Not Sleep on a Firm Mattress?

Certain sleepers actually need softer support or more sinkage to either keep their spines aligned or avoid pain. Take a look below to see who might benefit from a softer feel.

• Side Sleepers often do better on a soft to medium-soft mattress that helps alleviate pressure at their shoulders and hips. Some sinkage around the hips and shoulders actually helps keep your spine straight when you’re sleeping on your side. If you tend to sleep on your side more, I recommend reading through our review of the best mattresses for side sleepers.

• Sleepers with shoulder or hip pain can also benefit from the additional pressure relief a soft mattress offers, which can help alleviate pain and stiffness. If that sounds like you, head over to our best mattress for shoulder pain or best mattress for hip pain roundup to find the right fit for your needs.
• Lightweight sleepers often experience firm mattresses as even firmer than they’re intended to be, as I mentioned above. So, I often recommend these sleepers stick to more medium-firm or medium-soft mattresses to ensure they get enough pressure relief.
• Memory foam lovers who enjoy the feeling of “sinking” into bed often fare best on softer mattresses. If you want to feel like you’re really cuddled up inside your bed, instead of lifted up on top of it, one of our best soft mattresses could be a better fit for you.

How Do You Measure Mattress Firmness?

Here at Sleepopolis we measure mattress firmness using the mattress firmness scale. The scale ranges from 1-10, with 1 being the softest mattress ever and 10 being the firmest mattress ever. The industry standard for medium-firmness is a 6.5 out of 10. So if you’re looking for a firm mattress you should opt for a bed reviewers classify between 7 and 10 on the mattress firmness scale. Take a look below to learn more about mattress firmness levels, and check out our How to Choose a Mattress buying guide for some more info.

• 1-5: Mattresses that range from a 1-5 on the mattress firmness scale are truly soft mattresses. You’ll want to be careful to ensure a mattress in this range is supportive as well as soft. The Helix Sunset is a good example of a soft, but supportive, mattress.
• 6: Mattresses that fall at about a 6 on the firmness scale are medium-soft beds. Mattresses closer to a 6.5 are medium-firm. I’d recommend mattresses that fall in the 6-6.5 range for side sleepers. The GhostBed Luxe is a nice example of this type of bed.
• 7: Mattresses that get a 7 on the firmness scale are truly firm mattresses. The WinkBed above is a great example of a firm bed. Most sleepers on the hunt for a firm mattress should like a bed that falls at a 7 on the firmness scale.
• 8: Mattresses that score an 8 are extra-firm beds, and are especially good fits for stomach sleepers who need a lot of support. The Plank is a great example of an extra-firm mattress.
• 9: I’d describe these mattresses as ultra-firm, with almost no cushion at all. I’ve never reviewed a bed that falls at a 9 on the firmness scale.
• 10: I’d rank a hardwood floor as a 10 out of 10 on the mattress firmness scale. You’re very unlikely to ever encounter a bed this firm.

Pros and Cons of a Firm Mattress

Still not sure if a firm mattress is the right choice for you? Take a look at some of the pros and cons of firm mattresses to decide.

Benefits of a firm mattress

• Durability is a big perk of firm beds, which often last longer than soft mattresses. Choosing a high-quality firm mattress may help you avoid premature mattress sagging. But you can definitely find a durable soft mattress as well, so don’t let that determine your purchase.
• Firm mattresses can be more supportive than soft mattresses. Firmness is not the same thing as support, and it is possible to find a soft and supportive bed. But, if you’re looking for a lot of support, choosing a firm mattress is usually a safe bet.
• If you’re looking for great edge support, a firm mattress could be the way to go. The sides of these beds should support your weight without sagging or collapsing. This can actually make your bed feel a little bigger, which is a great added bonus!
• Since many firm beds use pocketed coil layers that promote airflow, they tend to sleep cool. This is a great perk for hot sleepers.
• Firmer mattresses often help you feel more “on top of the bed” than “stuck in” it. This could be nice for combination sleepers who need mobility for switching positions at night.
• It’s easier to distribute your weight evenly over the surface of a firm bed, which is a good way to alleviate aches and pains and prolong your mattress’s life.
• It’s easier for back and stomach sleepers to achieve a healthy spine alignment on a firm mattress. This means that these sleepers will be able to keep their spines straight (also known as a neutral spinal alignment) on these beds.

Drawbacks of a firm mattress

• If you’re looking for a soft and cuddly feel you may not get what you’re looking for on a firm mattress.
• You often need to sacrifice some pressure relief for support on firm beds. This is not a great feature for side sleepers or folks who struggle with shoulder or hip pain.
• If you like a slow moving mattress that offers some sinkage and hug, you won’t get what you need from a firm mattress. These beds tend to be more responsive.
• Side sleepers can struggle to keep their spines properly aligned on firm beds, which don’t allow enough sinkage around the shoulders and hips to let the spine drop into a neutral position.
