Best King-Size Mattresses

Our Expert’s Take

The Helix brand offers several mattress models of various firmnesses and feels, so no matter what position you sleep in, Helix should be able to set you up. And like all other Helix mattresses, the Helix Midnight has a high-quality hybrid construction. The Midnight stands out as our editor’s favorite king-size mattress because of its all-around quality in the sleep lab. For starters, the bed scored a 4/5 on our durability test—a sign of a sturdy, well-constructed hybrid mattress. Testers also gave the bed a 4/5 responsiveness score for the bed’s solid amount of give-and-take, which makes it easier to switch positions for combination sleepers.

The Helix Midnight mattress has a soft, breathable knit cover, with an option to upgrade to the cool-feeling GlacioTex Cooling Pillow Top for extra cushioning and a luxurious feel. You may not need that added cooling, though, if you don’t sleep hot—our testers rate Helix Midnight 4/5 for its cooling abilities even without the additional cooling layer. On our thermal gun test, the bed heated up by about 3.4 degrees F after human contact, which is a solid range. Comfort layers include a slow-moving memory foam, and a bouncier, denser transition foam for additional contouring and pressure relief. Finally, the support layer features up to 1,000 individually wrapped coils for support and airflow, which you can feel everywhere on the mattress: Helix Midnight earned a 4/5 score for its edge support from testers, who said they felt well supported on the bed’s perimeter. Our heaviest tester recorded a 2.25″ sinkage on the edge, which is better than a standard innerspring.

What We Love About the Helix Midnight

• Those prone to overheating throughout the night may find the cooling features of the Helix Midnight a welcome facilitator of temperature regulation.
• The Helix Midnight supports back and side sleepers very well, so much so that it can be a great option for those of you who have back pain. The hybrid build allows your hips and shoulders to sink in enough to get needed pressure relief, but not so much that your spine goes out of alignment. If you’re a stomach sleeper with back pain, however, this mattress might not be firm enough for you.

What to Keep in Mind About the Helix Midnight

• Stomach sleepers tend to need firmer mattresses, something that keeps their hips elevated so that their spines remain properly aligned—instead, consider the Helix Dawn.
• Our heavier mattress testers (over 230 lbs) found that the Helix Midnight may have caused some uncomfortable pressure buildup around their hips and shoulders.

Other User Reviews

On the Helix website, the Helix Midnight has 4.5/5 stars from 6,214 customer reviews. Many of these praise the balance between soft and firm as well as the support that the Helix Midnight provides. However, some negative reviews indicate a lack of motion isolation, as well as a saggy mattress perimeter.

Our Expert’s Take

Unlike the vast majority of mattresses on this list, the Nectar is an all-foam, memory foam mattress that really offers that classic memory foam experience. Lying down, testers experienced a slow sink into the bed. The memory foam will conform to your body and offer lots of pressure relief on a king-size bed.

While Nectar is a memory foam mattress, the bed doesn’t sleep too hot, testers who did the nap test said, awarding the mattress a 4.5/5 cooling score based on the bed’s feel and performance under the thermal gun (more on that below). Cooling materials include a breathable polyblend cover and memory foam with cooling gel infusions that both dissipate heat. And on par with the classic infomercials that demonstrated a memory foam mattress’ ability to absorb motion, Nectar also does an excellent job preventing movement across the surface: Testers gave the bed a 4.5/5 motion transfer score.

What We Love About the Nectar

• Thanks to the Nectar’s comforting memory foam layers, side sleepers may enjoy the pressure relief needed to keep their hips and shoulders comfortable and ache-free.
• People who sleep close to the edge of the bed probably won’t have any problem resting on the Nectar’s sturdy perimeter—the bed notched a 4/5 edge support score in the mattress lab after sagging only 3.5″ under our heaviest tester (who weighs about 250 lbs).
• The bed’s surface does not overly absorb heat like a typical memory foam bed. Based on our thermal gun analysis, after a tester rested on the bed, the surface temperature of the Nectar rose by less than 2 degrees F.

What to Keep in Mind About the Nectar

• Heavyweight sleepers may need firmer mattresses, as something too soft will likely allow them to sink uncomfortably far into the mattress. The Nectar, like most memory foam mattresses, is one such mattress that is simply too soft for most heavyweight people. Instead, we recommend Titan Plus Luxe.
• Like heavyweight sleepers, stomach sleepers usually do better on firmer mattresses. The Nectar simply doesn’t offer the support needed to keep their hips elevated in a comfortable position.
• If you like an all-foam bed with more bounce, you may want to consider a bed with latex foams instead. The Nectar has a slower-moving feel that notched a 3/5 score on our responsiveness test based on how quickly the foams reformed.

Other User Reviews

Based on a whopping 50,525 reviews on the Nectar website, the Nectar mattress earns an average score of 4.7/5. There are many reviews stating that the bed has helped mitigate aches and pains, particularly in people who are older. That said, there are many comments calling out the poor customer service that Nectar provides, with some users stating that they waited a very long time for their mattresses to be delivered.

Our Expert’s Take

The WinkBed—especially the king-size—is a luxurious hybrid mattress with a traditional innerspring feel. Among its many notable features are tall, supportive coils, zoning, and a plush pillow-top. The WinkBed is wrapped in a breathable Tencel cover that helps keep the bed from trapping heat, and the main comfort layer incorporates gel-infused foam for added cooling. Our testers gave the bed a 4/5 score in recognition of WinkBed’s cooling abilities.

The bed is also available in multiple firmnesses, so you can select from a Softer, Luxury Firm, Firm, or Plus model. The Luxury Firm is their most popular and we found it might be a great mattress for combination sleepers—comfortable and supportive for back sleepers, side sleepers, stomach sleepers, and anyone who switches between all of these positions.

What We Love About the WinkBed

• Those who switch sleeping positions throughout the night will enjoy the level of responsiveness that the WinkBed provides. In fact, our review refers to it as “a combo sleeper’s dream” because of how easy it is to move around on.
• The Tencel cover is very breathable, as are the individually wrapped coils that make up the support system of the bed. This means that hot air passes through the mattress rather than becoming trapped, making for a cooler sleep experience.

What to Keep in Mind About the WinkBed

• Couples likely won’t be too impressed with the WinkBed’s ability to isolate motion. If you’re a light sleeper who is easily disturbed by your partner’s movements, this will especially be a problem for you—instead, check out the Nectar Luxe.
• Shoppers looking for something a bit more plush and conforming might not feel comfortable on the WinkBed, which makes you feel more like you’re sleeping on top of the mattress rather than “in” it.

Other User Reviews

The WinkBed earned a 4.8/5, based on 8,414 customer reviews submitted to the WinkBed website. Much praise is given to the firm yet somehow soft feel of the mattress, as well as the ease-of-movement that the construction provides. Not all is well, though, as some customers found it lacking in pressure relief, resulting in hip and back pain.

Our Expert’s Take

A king-size mattress is a big investment. Odds are, you’ll be sleeping on this mattress for years to come, so you’ll certainly want to prioritize comfort. The DreamCloud Premier has you covered in this department, as its plush cashmere and foam blend pillow top provides luxurious cushioning that helps relieve pressure in sensitive areas of your body.

The hybrid construction underneath the quilted pillow top provides ample support, so this mattress really has the best of both worlds—the comfort of a soft foam mattress and the support and durability of an innerspring mattress. Testers felt the DreamCloud Premier’s build merited an overall support score of 4/5. Another area the Premier excelled in was cooling (4/5), thanks to the breathability of the coils and cooling gel memory foam comfort layers.

What We Love About the DreamCloud Premier

• Back and side sleepers of all shapes and sizes should find that the DreamCloud Premier has the perfect, middle-ground firmness that provides plenty of support but also the cushioning needed to relieve pressure.
• Couples who prioritize good motion isolation probably won’t need to worry about disturbing one another on the DreamCloud Premier, as this mattress does a good job of keeping movements from reverberating across the surface.

What to Keep in Mind About the DreamCloud Premier

• People who are older may have difficulty getting in and out of bed and have an easier time when the perimeter of the mattress is sturdy and doesn’t sag under applied pressure. Unfortunately, the DreamCloud Premier doesn’t excel here—check out the WinkBed instead.
• Heavyweight (over 230 lbs) stomach sleepers may want something firmer than the DreamCloud Premier to keep their hips from sinking uncomfortably far into the mattress.

Other User Reviews

Based on 3551 customer reviews on the DreamCloud website, this mattress has an average score of 4.5/5. Like ours, many of these reviews praise the DreamCloud Premier for accommodating many types of heavyweight sleepers. That said, some found it incredibly cumbersome and difficult to set up, which might especially be a problem if you plan to do it alone.

Our Expert’s Take

If you’ve visited some of our other best-of lists you may have noticed that the Saatva appears quite often. It’s true: We love this mattress, and the testing data speaks for itself. The two sets of coils, combined with a plush pillow top, deliver that luxury hotel feel that so many people look for. And sleepers who struggle with back pain will appreciate that the bed earned a 4.5/5 support score from mattress testers, indicating that the bed will keep your spine in its natural alignment. Plus, the Soft, Luxury Firm and Firm options mean that you can select the firmness that best matches your needs.

But for the best balance of comfort and support, we recommend the Luxury Firm model—this is also the model that we prodded, cut open, moved around on, and napped upon in our Austin, TX sleep lab. Our testers were able to get cozy in any sleep position, and the Luxury Firm also had excellent edge support (4.5/5) for sleepers who tend to favor their bed’s borders.

What We Love About the Saatva

• You know that feeling you get when you first enter a hotel room and plop down on the freshly made, perfectly supportive yet soft mattress? Well, thanks to the Saatva’s high-quality hybrid construction it delivers a similar combination of comfort and support.
• Sleepers who toss and turn throughout the night may appreciate how easy it is to move around on the Saatva, thanks to its layer of pocketed coils.
• Older people who may have trouble getting in and out of bed should find the sturdy edges of the Saatva provide them enough stability when placing their weight along the perimeter.

What to Keep in Mind About the Saatva

• Fans of the conforming feeling of memory foam may not appreciate the construction of the Saatva, which doesn’t allow you to sink too far into the mattress surface.
• Couples who value motion isolation will likely find that their partner’s movements reverberate a bit too much on the Saatva’s surface—check out the Nectar Luxe instead.

Other User Reviews

On the Saatva website, the classic Saatva mattress has 2,888 customer reviews with an average score of 4.8/5. Many of these reviews praise the high-quality, comfortable materials used in the Saatva, as well as the excellent customer service. On the flip side, a few customers were disappointed to find their Saatva sagging after just a few years.

Our Expert’s Take

If you’re looking for a king-size mattress that’s fit for a king, check out the Nolah Evolution as an option. You might be wondering how we define luxury when talking about a mattress. Well, most of it comes down to the quality of materials and construction. With a height of 15”, along with sturdy coils and an Edge Support System, this bed could last for at least 10 years while maintaining its structural integrity and support. Also, cooling features like its special heat escape gusset, its graphite-infused cooling foam, and its cooling cover earned the Nolah Evolution a stellar 5/5 on our temperature regulation test.

What We Love About the Nolah Evolution

• Side and back sleepers probably receive sufficient support and comfort from the Luxury Firm version of the Nolah Evolution, thanks to the middle-of-the-road firmness level and impressive hybrid construction which utilizes both high-quality foam and supportive coils.
• Shoppers who want a mattress with fantastic longevity will appreciate the durability of this mattress. If properly cared for, you can expect the Nolah Evolution to maintain its structural integrity for upwards of ten years.

What to Keep in Mind About the Nolah Evolution

• Stomach sleepers should look for something that does a better job of keeping their hips elevated. You’ll likely want to look at mattresses on the higher end of the firmness scale. For some great options, check out our list of the best mattresses for stomach sleepers.
• Budget shoppers may find the Nolah Evolution too pricey—consider the DreamCloud Premier for a more affordable luxury option.

Other User Reviews

Taking a look at customer reviews, on the Nolah website this mattress has an average rating of 4.9/5 based on 810 entries. Customers praise the back pain relief and temperature regulation that the Nolah Evolution provides, however, some find it too tall, making it awkward for them to get into bed. Also, several users complain that it is too firm for their liking.

Our Expert’s Take

When we say “best priced” we don’t necessarily mean cheapest. Rather, the Brooklyn Bedding Signature Hybrid earns a spot on this list because of its great value. The company owns its own factory, so the brand is able to cut out the middleman and price beds lower than many of the comparable competitors. The Brooklyn Bedding Signature Hybrid—outfitted with supportive coils and proprietary foams—is the brand’s most popular mattress and is priced at just a little over $1,000 after discounts.

The bed is swaddled in a thin, breathable cover that keeps you cool, with an option to upgrade to the Cloud Pillow Top for an even cooler feel than the 4/5 rating our testers gave the standard model of bed. It features three comfort layers: a 1.5″ quilted top that contours to your body and wicks away moisture, a 1.5″ bouncy layer for greater ease of movement, and a 1″ transition layer to prevent you from sinking in too much. You can select from Soft, Medium, and Firm models. Our tester tried the medium model, which he found to be a great fit for back sleeping.

What We Love About the Brooklyn Bedding Signature Hybrid

• The Brooklyn Bedding Signature has multiple firmness options, so no matter your body type or preferred sleeping position you should be able to find one that works for you. We like the soft option for lightweight sleepers, the medium option for average weight back sleepers, and the firm option for heavyweight sleepers and stomach sleepers.
• With sales, the Brooklyn Signature Hybrid can often be purchased for less than $1,000, which is an outstanding price for such a quality mattress.

What to Keep in Mind About the Brooklyn Bedding Signature Hybrid

• Couples will likely want more motion isolation than is offered by the Brooklyn Bedding Signature. Memory foam mattresses tend to excel in this area.
• Those looking for the bells and whistles of a luxury mattress might be a little bit underwhelmed by the lack of advanced cooling technology and robust comfort layers. If those things interest you, we suggest the Nolah Evolution Hybrid.

Other User Reviews

The Brooklyn Bedding Signature Hybrid has 10,148 reviews on the company website for an average score of 4.7/5. Many of the comments actually recommend this as a great option for an RV mattress. Some users find even the softest version of the Brooklyn Signature Hybrid too firm for them.

Our Expert’s Take

Bear designs its beds for athletes who may deal with aches and pains, and the secret is Celliant technology. The claim is that this material may assist with blood flow to promote muscle recovery, and can also keep you cool at night. Their highest-end model is the Bear Elite Hybrid.

When stretching out on the king-size Bear Elite Hybrid, our tester experienced a great deal of pressure relief, especially while on their back and side. And while we lack the lab equipment to test the bold claims made about the Celliant technology, our testers did experience noticeable cooling capabilities when napping on the Bear—particularly when it came to the hand-quilted cover, which felt cool to the touch, and helped the bed earn an overall cooling score of 4.5/5. The bed’s zoned comfort foam also includes airflow-promoting divots, since foam layers are the biggest culprit for trapping heat. The bed’s solid overall support score (4.5/5) is in part thanks to the individually-encased coil layer (also known as pocketed coils), along with extra coils around the perimeter, adding to the bed’s excellent edge support (4.5/5).

What We Love About the Bear Elite Hybrid

• For folks who sleep too hot, the Bear Elite’s cooling cover helps to lower body temperature helping you sleep cool at night.
• Athletes looking for something that could help optimize recovery may find that the Bear Elite Hybrid does just that. While we can’t speak to whether or not the Celliant technology actually helps promote blood flow, we will say that the support and pressure relief we felt on the mattress might help mitigate aches and soreness.

What to Keep in Mind About the Bear Elite Hybrid

• Heavyweight (over 230 lbs) stomach sleepers will want a firmer mattress than the Bear Elite Hybrid, as this will help keep their hips from sinking uncomfortably into the mattress. We suggest the Plank Firm.
• The Bear Elite Hybrid costs over $2,000 for a queen. Shoppers with a strict budget might need to look elsewhere.

Other User Reviews

On the Bear website, the Elite Hybrid has 4.4/5 stars based on 263 reviews. Many users praised the pain relief and cool night’s sleep that the Bear Elite Hybrid provides. A few people, on the other hand, found the middle of the bed too soft, causing an uncomfortable dip in the center of the mattress.

Our Expert’s Take

The Plank mattress, made by Brooklyn Bedding, is an extra firm, flippable mattress, coming in at 8/10 on our firmness scale for the firm side and 9/10 on the extra firm side. It’s designed to create an extremely flat sleeping surface that your body probably won’t sink into at all. It has an extra-firm side with 0.75″ of quilted polyfoam for minimal softness, and a firm side with the same quilted polyfoam, plus 2″ of bouncy Supreme Response Comfort Foam for a bit more pressure relief. Though firmness is subjective, we found the Plank mattress felt very firm, and we’re sure just about everyone will agree.

If you’re an extra-firm mattress lover who also sleeps hot, you can pay an upcharge and Brooklyn Bedding will sew a cooling panel into Plank Firm’s top layer on each side, known as the GlacioTex Cover. The mattress support comes from a 7″ high-density base foam layer, giving it an overall 11.5″ height, which is more on the sparse side, however, the thinness adds firmness without compromising support: The mattress scores 5/5 for both overall support and edge support from testers. For those who prefer coils, check out the Plank Firm Luxe.

What We Love About the Plank Firm

• The Plank is a flippable mattress, which is a great option for folks who aren’t sure which firmness is best for them. Both sides of the Plank are very firm, but the difference between the sides is noticeable.
• Heavyweight people will likely feel comfortable on the Plank given its high firmness, which will keep them properly supported. Back sleepers will probably do best on the softer side, while the firmer of the two sides will work better for heavyweight stomach sleepers.

What to Keep in Mind About the Plank Firm

• Side sleepers will almost certainly want something with more cushion for their sensitive pressure points (hips and shoulders). Instead, consider the Helix Midnight.
• If you find yourself getting uncomfortably hot at night you may want to look for a mattress with more cooling abilities than the Plank Firm.

Other User Reviews

Based on 2,642 reviews from the Plank website, this mattress has an average score of 4.8/5. Many of the customers who were looking for a very firm mattress are clearly pleased with Plank making good on their promise. However, there are a select few who surprisingly claim this mattress simply isn’t firm enough. Of course, this is entirely subjective, but as someone who has tested it, I can honestly say I can’t imagine a firmer mattress.

Our Expert’s Take

Another Brooklyn Bedding mattress, the Titan Plus is specifically designed for heavier sleepers. It comes in at 9/10 on our firmness scale, making it one of the firmest mattresses on this list. It’s a great option for supporting heavy sleepers who typically sleep on their stomach. Don’t worry, though—it doesn’t feel like sleeping on a concrete slab. It’s a hybrid mattress, so you’ll get an innerspring feel with a slight foam feeling on top.

The Titan Plus also features a polyester cover with 1″ of gel memory foam for cooling comfort that maintains its shape, and like the Plank Firm, you can add a GlacioTex cooling cover for extra coolness. The comfort layer is 2″ of bouncy TitanFlex foam for responsive contouring and pressure relief. It has an 8″ support layer of durable coils and a 0.25″ high-density foam base for added support. The build is a lower profile—11″ total—but offers plenty of support, with a 4.5/5 support score earned from our heavyweight tester Marten.

What We Love About the Titan Plus

• This firm mattress may offer the support that heavyweight sleepers need in order to keep everything exactly where it should be. Many times, softer mattresses allow the hips and shoulders of heavier people to sink deep into the mattress, thereby throwing the spine out of alignment and potentially causing discomfort. With the Titan Plus, this is not an issue.
• Stomach sleepers, like heavyweight sleepers, tend to appreciate firmer mattresses like the Titan Plus. They too need their hips to stay supported and elevated as they sleep, or they risk waking up with back pain.

What to Keep in Mind About the Titan Plus

• Side sleepers will likely find the Titan Plus too firm. Unlike stomach sleepers, side sleepers likely want their hips and shoulders to sink into the mattress a bit, as this helps keep pressure from building up in those sensitive areas. Go for a softer mattress like Helix Midnight instead
• Couples might want something that isolates motion more effectively so they don’t disturb each other while changing sleeping positions or getting in and out of bed.

Other User Reviews

The Titan Plus has an average rating of 4.7/5, based on 2,433 customer reviews from the Titan website. Many rave about the high-quality firm construction that’s great for heavyweight sleepers. Unsurprisingly, some users complain that the Titan Plus is too firm and very difficult to get comfortable on.
