Best King-Size Mattresses of 2024

We have affiliate relationships where we are paid a commission on sales through some of our links. See our disclosures.

At 76 inches wide by 80 inches long, a king-size mattress can be a sensible choice for anyone who needs more space than what’s offered by a full, twin, or queen bed. Maybe you sleep with a partner or pet and want additional room to spread out. Maybe you have a larger body type and simply require a wider sleeping surface. Or maybe your reasons for wanting the best king-size mattress are more aesthetically minded; for instance, you might have a large master bedroom that needs bigger furniture for a nice visual balance.

Below, we’ve put together an informed list of the best king-size mattresses for a variety of body types, budgets, and sleeping positions. Not only do we put each bed through an extensive battery of tests that measure performance factors such as cooling, motion isolation, and pressure relief — we also vet every product’s trial period, shipping policy, and warranty.

Our Top Pick for King Mattresses

A king mattress is often favored by heavy people, combination sleepers, and couples, all of whom benefit from strong edge support. The Helix Midnight Luxe gives them just that, thanks to its sturdy hybrid construction. The layer of springs provides support and cooling, while the foam top layer makes the bed comfortable and pressure relieving.

What We Look for In a King Mattress

Support

The support of your mattress is important to you, and we know this, so we were sure to test each of the mattresses in this list ourselves so you can be sure you are getting a comfortable king-sized mattress that is still supportive. We tested the supportiveness of each mattress for various sleeping positions using a pressure map, which uses thermal technology to show us where pressure is relieved on the body when laying on the mattress.

Edge Support

We’ve found that one of the benefits of a king mattress is that the additional size allows you to fully spread out and use the whole surface of the bed. However, if a mattress has weak edges, you lose some of that valuable space to spread out and stay comfortable. Your mattress may also deteriorate faster if it has weak edges. Because of this, we personally tested the strength and support of all of the edges on these mattresses to help you stay comfortable and keep your mattress intact for longer.

Trial Period and Warranty

We know that king-sized mattresses can be pricey investments, but if your bed has a generous trial period and/or warranty, you get the assurance of longevity. We know this is important for you when investing in something like a king-size mattress, so we looked into the trial period and warranty for all of the mattresses in this list to help you find the one best suited to your budget and needs.

Helix has a line of six hybrid mattresses, each with a different level of firmness. The Midnight is one of their medium models. It has enough contouring for side sleepers, but should still be supportive enough for back sleepers, as long as they don’t mind a softer bed. Learn more in our video review.

What our tester says:

“I like the Helix Midnight Luxe for back sleepers and side sleepers. The medium-soft to medium-firm feel should give these folks the right balance of comfort and support.” – Nichole Mondshein, lead reviewer and mattress tester

Expert Opinion

Helix is known for its line of customizable mattresses, and we’re especially drawn to the hybrid Midnight Luxe, which earns the best overall spot. This king-size bed starts with a breathable Tencel cover and includes two more inches of comfort foam than the standard Helix Midnight, as well as a plush pillow top layer. We felt lots of pressure relief when lying down on the Midnight Luxe, but decided it has an overall medium-firm feel. For those with back pain, the Midnight Luxe has zoned support. It should be extra-soft around the shoulders to prevent stiffness while providing more support for the hips, helping to alleviate and prevent back pain.

The Helix Midnight Luxe is a hybrid mattress, meaning that it has one layer of cushioning, comfortable, and luxurious foam, and one layer of individually wrapped coils. These coils help to keep the mattress breathable yet supportive, and the foam makes the bed comfortable and continuing. This is an excellent pick for most sleepers, especially back and side sleepers, who will like the support and contouring of this bed.

What our tester says: “[The Midnight Luxe’s] coils have zoned support, which means that they’re softer at the shoulders for added pressure relief and firmer at the hips to help promote a neutral spinal alignment. This is a wonderful pick for back and side sleepers, and anyone who likes a contouring feel without missing out on support.” — Nichole Mondshein, lead reviewer and staff writer

Customer Reviews

On Helix’s website, there are almost 6,000 reviews for the Midnight Luxe, with an average rating of 4.4 out of 5 stars. Reviewers rave about the comfort and support of this mattress, and agree that the bed is cooling, comfortable, and supportive.

Highlights of the Helix Midnight Luxe Mattress

  • Many shoppers looking for a king-size bed sleep with a partner. These folks should sleep comfortably on the Midnight Luxe, as it has good edge support, low motion transfer, and cooling capabilities.
  • The balanced feel of the Midnight Luxe works well for back sleepers and side, as it helps them maintain a healthy spinal alignment while still feeling comfortable.
  • The coils in the mattress help to keep it cool and breathable, which is great for sleepers who like to stay cool throughout the night.

What to Keep in Mind about the Helix Midnight Luxe Mattress

  • Many stomach sleepers will likely find the Midnight Luxe too soft. They’ll likely benefit from a firmer mattress to keep their hips from sinking into the bed.

The Nectar Classic is a memory foam mattress that provides solid support for most light to average weight sleepers. The cushioning memory foam allows for plenty of pain relief around the lower lumbar spine. Most back sleepers and side sleepers should enjoy the pressure relief. Plus, a lengthy trial period, lifetime warranty, and affordable price make the Nectar a reassuring choice for many. Watch our video review to learn more.

What our tester says:

“I think the Nectar Classic does a great job of relieving back pain. The pressure map test results show a lot of blue and green on our backs, meaning back sleepers should experience good pressure relief from the Nectar.” – Nichole Mondshein, lead reviewer and staff writer

Expert Opinion

We think that those wanting an all-foam bed that’s supportive enough to help relieve back pain will love the Nectar Classic. Its therapeutic memory foam helps with pressure relief around the lower lumbar spine. Unlike other all-foam mattresses, the Nectar provides sufficient support so you don’t sink too far in of the material and throw your spine out of alignment. Also, we were impressed with the edge support the Nectar has, which is an indication you’ll be able to make full use of your king bed’s surface.

Memory foam is known for its pressure relief, and during our pressure map test, the graphic showed minimal pressure buildup while we were lying on our backs. This tells us that the Nectar should be a good mattress for individuals who suffer from back pain. Side sleeping, we found moderate pressure, or lots of green, at the shoulders. We found a little yellow at the hip. This means that folks with severe hip pain might want a more pressure-relieving, but those with shoulder pain should be alright.

What our tester says: “I think memory foam lovers should be happy on the Nectar. This bed has a classic memory foam feel, so there’s lots of sinkage, contouring, and pressure relief. This can be great for anyone with shoulder pain or hip pain since it gives them cushioning at sensitive pressure points.” — Nichole Mondshein, lead reviewer and staff writer

Customer Reviews

There are almost 51,000 customer reviews on the Nectar website, which is a testament to the mattress’s popularity. Over 2,200 of these users state that they bought a king. One verified buyer wrote, “My husband and I bought a queen for the spare bedroom, but after trying it out, we kept sneaking naps on it because it was so comfortable. Six months later, we bought a king for ourselves.”

Several folks also point to Nectar’s generous lifetime warranty and 365-night trial period. This kind of promise of longevity is important for memory foam mattresses, as they tend to not be as durable as hybrids and innersprings.

Highlights of the Nectar Mattress

  • For back sleepers who love a softer feel, the Nectar provides cozy cushioning without causing the sleeper to feel enveloped.
  • The soft foams of the Nectar should provide side sleepers with plenty of pressure relief around the shoulder and hip.
  • Available for an affordable price, the Nectar is a good option for budget shoppers.

What to Keep in Mind about the Nectar Mattress

  • Most stomach sleepers won’t get enough support from the Nectar to keep their hips lifted up and maintain their spinal alignment.

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

Expert Opinion

We think this pillow top hybrid mattress by WinkBeds is a match made in heaven for couples. It has strong edge support, so you can use the entire surface without feeling like its sides might collapse. The WinkBed was also bouncy and supportive when we laid down on it, which is a nice perk for sex, and the bed’s comfort foams are infused with cooling gels that work to prevent the trapping of body heat. A versatile option, the WinkBed is available in Softer, Luxury Firm, Firmer, and Plus versions.

One of the most important factors in a mattress for couples is motion transfer, which we test in our lab by dropping a 10-pound steel ball from three different heights. From there, we measure the level of disturbance caused by the drops. Low levels of disturbance indicate low motion transfer, while high levels of disturbance indicate high motion transfer. In a mattress for couples, we recommend looking for a bed with low motion transfer. That way, the bed will trap movement and prevent you or your partner from feeling each other tossing and turning at night. While testing the WinkBed’s Luxury Firm model, we didn’t see the vibrations spiking too much, thus indicating overall low motion transfer.

What our tester says: “I’m confident that couples should find everything they need in the WinkBed, including cooling, responsiveness for sex, exceptional motion isolation, and plenty of edge support.” — Nichole Mondshein, lead reviewer and staff writer

Customer Reviews

On the brand’s website, the WinkBed has an average customer rating of 4.8 out of 5 stars, averaged from over 8,000 customer reviews. One verified shopper commented, “My wife and I love this mattress. It’s the perfect blend between the things we like about a spring mattress and the things we like about a memory foam mattress.”

Highlights of the WinkBed Mattress

  • The WinkBed’s bouncy nature makes it a great choice for combination sleepers, as they can easily switch between sleeping positions. This also makes it a choice for sex, which may be a factor if you are shopping with your partner.
  • The sturdy support the WinkBed provides, along with cushioning from the Euro pillow top, make it an ideal choice for relieving lower back pain for most sleepers.
  • Tall pocketed coils allow for lots of airflow in the WinkBed, plus gel infusions and a Tencel cover promote cooling, making it a good choice for hot sleepers.

What to Keep in Mind about the WinkBed Mattress

  • The WinkBed is a high-quality, well-constructed mattress, and the price reflects that. It may not be the best option for budget shoppers.

The DreamCloud Original is a hybrid mattress with a luxurious feel that back sleepers in particular will love. The coil layer keeps the bed breathable and cool while still being supportive. The memory foam top layer helps make the mattress comfortable, and gives it that luxurious and contouring feel without being too soft, ranking as a 7 out of 10 on our firmness scale.

What our tester says:

“The DreamCloud got a 7 from me because it strikes a nice balance between pressure relief and support. There’s some gentle cushioning up top, as well as some firm bounce in the bed’s core. I think this feel could work well for anyone who likes to feel more lifted up by their bed rather than stuck in it..” – Bridget Chapman, former senior product editor

Expert Opinion

The DreamCloud Original mattress is a hybrid bed, meaning that it is made with one layer of memory foam and one layer of coils. The coils on the bottom of the mattress provide the necessary amount of support through the back and hips to promote spinal alignment. Above the coils, the construction consists of a cashmere blend cover, memory foam, a foam transition layer, and a base layer, all of which help keep create a luxurious sleeping experience.

The coils on the DreamCloud also help keep the bed durable and give it good edge support, which is important for a king-size mattress, as you want to be able to spread out and use the entire bed. The foam on the top prevents the mattress from being overly firm, while still keeping it supportive. We rated the DreamCloud a 7 out of 10 on our firmness scale, where 1 is the softest and 10 is the firmest.

What our tester says: “The DreamCloud is made with high-quality materials and has gel infusions and coils, which help the bed sleep super-cool, while still being both supportive and contouring. It has a very luxurious feel because of its construction .” — Bridget Chapman, former senior product editor

Customer Reviews

Over 8,000 reviewing customers agree that the DreamCloud is an extremely comfortable and cooling mattress. Many reviews agree that the bed gave them some of the best sleep they have ever had, with one reviewer saying they have never slept better.

Highlights of the DreamCloud Original Mattress

  • The coils in the DreamCloud’s bottom layer leave plenty of room for airflow, making it a good option for people who sleep hot or like to stay cool throughout the night.
  • This is a responsive mattress, so combination sleepers should be able to easily change sleeping positions.
  • The DreamCloud Original is rated as just above medium firm, making it an excellent choice for back sleepers.

What to Keep in Mind about the DreamCloud Original Mattress

  • The DreamCloud Original mattress is likely too firm for strict side sleepers, who may need more contouring around their shoulders and hips.

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

Expert Opinion

Available in three different firmness levels (Plush, Luxury Firm, and Firm) the Nolah Evolution provides lots of contouring and pressure relief, no matter which model you choose. The plushness comes from the brand’s proprietary AirFoamICE, which let us comfortably sink into the mattress when we tested it. The soft comfort foams in the upper layers provide the coziness, while the coil base layer provides support for an overall balanced feel. We felt lots of cushioning and sinkage lying on the Nolah Evolution. Naturally, we’d recommend the Plush version for shoppers seeking a soft mattress, but even the Luxury Firm model we tested provided lots of cushioning.

While testing, we put the Nolah Evolution’s Luxury Firm version through our pressure map test. We saw low pressure (blue) while we were back sleeping, and we saw green at the shoulder and a tad yellow at the hip while we were side sleeping. These results tell us that, overall, the Luxury Firm model of the Nolah Evolution is an effective mattress for joint pain. The softer Plush model will likely provide even more pressure relief for those with lots of sensitivity in these areas.

What our tester says: “One of my favorite features is the soft pillow top. It’s a great touch for anyone [living with] shoulder or hip pain, as it allows you to sink into bed for a plusher feel.” — Bridget Chapman, former senior product editor

Customer Reviews

On Nolah’s website, the Evolution has an average customer rating of 4.9 out of 5 stars. One five-star review from a verified customer praised the pressure-relieving abilities of the bed’s soft foams, especially for elderly people. “It has eliminated hip discomfort for my wife,” they wrote. “It is softer than we are used to, but as we’ve gotten older, it is much more comfortable than the firm mattresses we used to have.”

Highlights of the Nolah Evolution Mattress

  • With breathable foam and airflow-promoting coils at the bottom, the Nolah Evolution is great for hot sleepers.
  • The Nolah Evolution is also adept at relieving hip and shoulder pain, making it an excellent fit for side sleepers.
  • Back sleepers preferring a softer mattress should love the 8-inch layer of support coils.

What to Keep in Mind about the Nolah Evolution Mattress

  • The Nolah Evolution is a higher-end mattress; it may not be a great pick for budget shoppers.

Pros of the Saatva

Its bouncy and responsive feel means it’s great for combination sleepers
The Saatva’s reinforced edges give it some of the best edge support we’ve ever seen
Cons of the Saatva
If you’re looking for lots of sinkage or amazing motion isolation, you’re better off with one of the best memory foam mattresses.
None of the Saatva Classic models will likely be supportive enough for heavy stomach sleepers. For these folks, we recommend the Saatva HD.

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

Expert Opinion

We found that the Saatva’s bouncy innerspring construction offers firm support, keeping our spine aligned when we laid down on it. Built with a coil-on-coil construction, this mattress offers a traditional innerspring feel that is still comfortable thanks to a Euro top layer. Its durable steel coils in the support layer prevent sagging and provide lots of back support and spinal alignment, which is important for sleepers with back pain. We also love how the Saatva offers three firmness levels (Plush Soft, Firm, and Luxury Firm), so it should work for most body types and sleeping positions.

A really important factor for king size beds is edge support. After all, there’s typically more than one person sleeping on a king. Edge support, or the strength of a mattress’s perimeter, tells us whether or not folks will be able to lay on its edges and make full use of the surface. When testing the Saatva, we found some outstanding edge support results. While lying on or just sitting on the mattress, we felt lifted and didn’t feel the mattress collapsing at all under our weight.

What our tester says: “I found the Saatva Classic to be a bouncy, high-quality mattress with durability and great edge support. The coil on coil construction help with support and spinal alignment, making this a good option for sleepers with back pain” — Nichole Mondshein, lead reviewer and staff writer

Customer Reviews

Of the nearly 3,500 reviews on Saatva’s website, 423 of the users purchased a king, with many of them remarking how the larger size only added to the sense of luxury. “It feels exactly like you’re sleeping on a Hyatt bed,” wrote one reviewer. Reviewers also agree that they felt comfortable but still supported on the Saatva bed.

Highlights of the Saatva Mattress

  • The Saatva provides lots of support for back sleepers, but still gives them lots of cushioning around the lumbar region. We especially recommend the Luxury Firm model for these sleepers.
  • The coils inside the Saatva Classic mattress make it especially bouncy, making it easy to switch between sleeping positions. This is great news for combination sleepers who need to switch positions at night.
  • The Saatva’s innerspring construction make it supportive enough for sleepers with back pain to have proper spinal alignment, but the Euro top later helps to keep the bed contouring, which is important for sleepers with pain.

What to Keep in Mind about the Saatva Mattress

  • The high number of coils utilized in the Saatva contribute to higher motion transfer, so if you sleep with a partner and are easily disturbed by their movements at night, the Saatva may not be an ideal choice.

The Bear Elite Hybrid uses foam and coils for a mix of support, cushioning, and cooling. While designed for athletes prioritizing wellness and recovery, sleepers of all activity levels can enjoy the many luxurious features. Enjoy zoned support for targeted relief, an “on top of” feel allowing for ease of movement, and cooling features throughout. For more information, watch our video review.

What our tester says:

“I’d recommend the Bear Elite Hybrid for most back and stomach sleepers.I think these sleepers will get the needed pressure relief and contouring around the lower back and hips. This mattress does a wonderful job at offering body contouring while still helping the sleeper stay elevated and lifted as well. The layers of foam should provide comfort while the coil system should offer lots of support.” – Nichole Mondshein, lead reviewer and mattress tester

Expert Opinion

Bear mattresses stand out from other beds because an extra fee can add a material called Celliant, which they’ll add to the cover of the Elite Hybrid. Celliant is soft, breathable, and reportedly promotes muscle recovery and blood flow, making the Bear a popular choice among athletes and anyone looking to recover after an active day. While we haven’t verified the healing properties of Celliant ourselves, there are many clinical trials that have, and we can attest that the Elite Hybrid’s cover helps us stay cool (also an important trait of a mattress for athletes).

Further cooling comes from the Bear Elite Hybrid’s bottom layer of coils, which leave plenty of room for airflow and gave us some bounce. The bed comes in three different firmness levels, and we tested out the Medium. On our mattress firmness scale, it came in at a 6 out of 10, so it’s definitely on the softer end.

What our tester says: “Bear claims that Celliant absorbs your body’s energy, then reflects it back to you to assist with blood flow and muscle recovery. Full disclosure: we haven’t tested this ourselves at Sleepopolis, but the material has undergone several clinical trials that you can read about here. I can say that, like phase change material, Celliant sleeps nice and cool.”  — Nichole Mondshein, lead reviewer and staff writer

Customer Reviews

With a little over 3,700 user reviews on the Bear website, the Elite Hybrid has an average customer rating of 4.7 out of 5 stars. Since we haven’t verified the recovery properties of Celliant ourselves, we wanted to see what verified buyers had to say. In a five-star review, one of them wrote, “I love the Celliant cover, it’s crazy how effective it is. You won’t really feel it working, but you will definitely feel recovered after a good sleep.”

While this shouldn’t be viewed as a concrete medical testimonial, it appears that lots of sleepers really do enjoy Celliant as a material.

Highlights of the Bear Elite Hybrid Mattress

  • Thanks to the three different firmness options of the Bear Elite Hybrid (Soft, Medium, and Firm), back, side, and stomach sleepers of most body types should be able to find a suitable option.
  • With good motion isolation results, a fairly responsive surface (good for sex), and cooling capabilities, the Bear is a good pick for couples to share.
  • Those with back pain should find the mix of pressure relief and support from the Bear Elite Hybrid beneficial.

What to Keep in Mind about the Bear Elite Hybrid Mattress

  • The Bear Elite Hybrid is a luxury mattress with a number of special features, so it’s a pricier option.
  • The Celliant cover that helps with cooling must be purchased separately for around $130.
