Best King Mattress of 2026

During our hands-on tests, the Midnight earned its most favorable ratings from side and back sleepers weighing up to 230 pounds and stomach sleepers under 130 pounds. That said, some of our testers found the mattress either too soft or too firm.

We found the Midnight performed well for motion isolation and pressure relief, two testing areas where hybrids often struggle. At the same time, the mattress is responsive enough to resist deep sinkage, and the reinforced perimeter helps ensure decent edge support. You may notice some initial off-gassing odor, but our tests suggest these smells will dissipate in a day or two.

Construction Breakdown

The Midnight Luxe begins with a two memory foam comfort layers, followed by a polyfoam transitional layer. Pocketed coils and dense base foam make up the support core. The perimeter coils are thicker to reinforce the edges and prevent you from sinking too deeply when getting in and out of bed. A breathable Tencel cover encases the mattress, and you can upgrade to a heat-dissipating GlacioTex cover for an extra fee.

After testing all three firmness levels, our team has determined the medium (5) design is a good match for side and back sleepers under 130 pounds. This model conforms closely to cradle and hug the body, and shouldn’t sink too much for people in this weight group who use the side and/or back positions. If you weigh 130 to 230 pounds, you may need the more balanced medium firm (6), while those who weigh more than 230 pounds should consider the ultra-supportive firm (7) design.

We were particularly impressed with the Sapira Chill Hybrid during tests for motion isolation and pressure relief – two performance areas where coil mattresses often struggle. The thick foam layers cushion sore spots and prevent movement from transferring across the surface. That said, the mattress also sleeps fairly cool. This is thanks in part to a cooling gel infusion in the top layer and steady airflow through the coil system.

Construction Breakdown

The Sapira Chill Hybrid’s comfort system consists of gel-infused polyfoam sewn to the Euro-top cover, followed by secondary layers of memory foam and adaptive polyfoam. A fourth layer of transitional foam creates a comfy buffer between your body and the support core, which contains pocketed coils and dense base foam. The coils are zoned to feel more robust beneath your midsection, and reinforced along the perimeter to protect the edges from compression when you get in and out of bed.

The CopperFlex Memory Foam is medium firm (6). After evaluating the mattress in our Test Lab, we found it best suited to side sleepers weighing 130 pounds or more, back sleepers weighing 230 pounds or less, and stomach sleepers under 130 pounds. The mattress hits a sweet spot for people who want a plush, adaptive surface that pushes back enough to keep their body on an even plane.

Motion isolation proved to be a major strength during our tests. All six of the CopperFlex’s layers work together to absorb movement and prevent motion from transferring to other areas of the mattress. This is key for couples and co-sleepers. For temperature control, we noticed some heat buildup on the surface, but this is to be expected of an all-foam bed. Overall, the CopperFlex slept noticeably cooler than many of the other foam models we’ve tested.

Construction Breakdown

The CopperFlex’s first layer consists of adaptive polyfoam quilted to the cover, followed by two memory foam layers that create a close contour around your entire body. A zoned transitional layer provides additional cushioning while pushing back against your midsection and preventing you from sinking too deeply into the mattress.

Two high-density polyfoam layers make up the support core and stabilize the mattress. The cover is made of GlacioTex fabric designed to feel cool to the touch at all times and dissipate body heat.

The most comfortable version of the Saatva Classic for any given person depends on their body weight and primary sleep position. During our hands-on tests, the soft model was most popular among our side sleepers weighing up to 230 pounds and our back sleepers under 130 pounds. This model contours very closely to cushion your body and reduce pressure along your spine. The firm design provided adequate reinforcement for our back and stomach sleepers weighing at least 130 pounds, as well as our side sleepers over 230 pounds. If you’re looking for a balance of conforming and support, we recommend the medium firm. We found this the most balanced design of the three.

The Saatva Classic excelled at cooling, particularly the medium-firm and firm models. We also measured minimal perimeter sinkage on these models during our edge support tests, and most of us could move across them without sinking too much. The soft Classic outperformed the firmer models in other areas, including motion isolation and pressure relief.

Construction Breakdown

The Classic is available in three firmness levels: soft (3), medium firm (6), and firm (8). All three share the same general construction, which begins with a Euro-top cover. Layers of adaptive foam and fiber fill give the mattress an invitingly plush surface, while a strip of dense memory foam cradles the lower back. Even on the firmest model, we noticed deep cushioning from these layers. The pocketed, mini-coil transitional layer maintained an even surface for our bodies, resulting in minimal sinkage for most of our testers.

The support core contains recycled-steel hourglass coils with a low gauge of 13, ensuring robust support. You can choose between an 11.5-inch mattress with 4-inch coils or a 14.5-inch model with 7-inch coils. We recommend the latter for people weighing more than 230 pounds, though our tests showed both designs are highly supportive. A cover made of breathable organic cotton encases the entire mattress.

We found that the Softer WinkBed conforms more closely than its firmer counterparts. This mattress was most popular among our side sleepers up to 230 pounds and our back and stomach sleepers under 130 pounds. The Luxury Firm will likely meet your needs if you’re seeking a balance of cushioning and support. This model earned stellar ratings from our side, back, and stomach sleepers across most weight groups. If you weigh more than 230 pounds and sleep on your back or stomach, then the Firmer or WinkBed Plus should provide adequate support.

Our testing also indicates the mattress is a good option for hot sleepers, thanks to the breathable Tencel cover and a coil system that promotes steady air circulation through the interior. Other strengths of the mattress include strong edge support, good ease of movement across the surface, and above-average motion isolation.

Construction Breakdown

Standard WinkBed models include the Softer (4), Luxury Firm (6), and Firmer (7). These mattresses begin with Euro-top layers containing adaptive foam, followed by an additional foam layer. We found that the cushioning level varied by firmness, but all three standard designs contoured evenly to distribute our weight and reduce pressure in sensitive spots like the shoulders and hips. The fourth option, WinkBed Plus (8), swaps out the second layer for responsive latex, resulting in a more supportive feel. WinkBed has specifically designed the Plus for people who weigh more than 230 pounds, and this claim was confirmed by most of our testers in this weight range.

All four WinkBed models contain pocketed coil support cores. The coils are divided into zones based on where people carry more weight. Our testers noticed significant pushback around the torso and hips and a gentler feel beneath the head, shoulders, and legs. Extra reinforcement stabilizes the perimeter to reduce sinkage when you get in and out of bed. Thanks to this configuration, most versions of the WinkBed aced our edge support tests.

The Evolution 15 comes in three firmness levels — medium (5), medium firm (6), and firm (7). Our testing found the plushest model suitable for side sleepers up to 230 pounds and back sleepers weighing under 130 pounds, who often prefer extra cushioning for pressure points. The medium-firm feel was the most versatile, appealing to our side sleepers over 230 pounds, back sleepers up to 230 pounds, and stomach sleepers between 130 and 230 pounds. Our back sleepers who weigh at least 130 pounds and stomach sleepers over 230 pounds enjoyed the firmest model’s even contouring.

Depending on the firmness level, the Evolution 15 varied in performance across our testing criteria. The softest model absorbed most movement transfer and noise, making it a great choice if you share the bed with a restless sleep partner. Couples who value responsiveness for sex may prefer the two firmer models, which earned higher marks in our ease of movement and edge support tests. All models performed exceptionally well in our temperature regulation tests, thanks to the breathable cover and airflow through the support core.

Construction Breakdown

A Euro-top quilted with polyfoam begins the Evolution 15’s comfort system, giving the surface a plush feel. Underneath is graphite-infused polyfoam that offers cushioning to pressure points. The graphite in this layer is engineered to absorb and dissipate excess body heat. A transitional layer of polyfoam acts as a buffer between the comfort system and coils, preventing you from sinking too deeply.

Pocketed coils in a zoned configuration make up the support core. These coils offer ample pushback to the midsection, where many people carry a disproportionate amount of weight. Extra coils also line the perimeter of the mattress to reinforce the edges. The coils rest on a polyfoam base layer for extra stability. A cover made from ArcticTex fiber, which is engineered for cooling, encases the mattress.

Our testers noted that all Aurora Luxe models offered a great balance of cushioning and support, but each provides distinct benefits depending on your sleep needs and preferences. Our side and back sleepers who weigh under 130 pounds enjoyed the softest model’s plush feel. The medium firm model was the most versatile and balanced. It performed best among side sleepers between 130 and 230 pounds, as well as back and stomach sleepers under 130 pounds. If you are a back or stomach sleeper weighing at least 130 pounds, you may prefer the firmest model’s even support.

Our testing found the mattress alleviates pressure points very well across firmness levels. We also recommend all models for couples who don’t want to choose between a mattress that isolates motion and one that’s responsive for sex. However, we recommend opting for the softer model if you prioritize motion isolation.

Construction Breakdown

The Aurora Luxe comes in three firmness levels: medium soft (4), medium firm (6), and firm (7). All three feature a top layer made from CopperFlex polyfoam, a proprietary foam that’s more responsive while still adding cushioning. The foam is infused with copper engineered to conduct heat away from your body and phase change material meant to regulate temperature. Next is a layer of responsive TitanFlex foam that prevents you from sinking excessively. For an additional fee, you can upgrade your mattress with an extra foam layer in the comfort system. This layer is known as the “Cloud” pillow-top, and will make your sleep surface feel a bit softer.

Depending on the firmness option you choose, the comfort system’s final layer differs. The two softer models have an adaptive gel-infused memory foam layer that acts as a buffer between your body and the coil support core. Meanwhile, the firmer option has a second layer of TitanFlex foam to help you maintain healthy sleep posture.

The support core uses pocketed coils in a zoned configuration. Thinner coils cushion your legs and shoulders while thicker ones provide pushback to your midsection and bolster the mattress perimeter. A polyfoam base layer prevents the coils from shifting, and a fabric cover with phase change material encases the mattress.

The Elite Ultra Hybrid’s medium (5) design earned its most favorable ratings from our side and back sleepers under 130 pounds. This model contours closely to the body. Despite the zoned coils, you’ll feel a close “hug” from the mattress. Our testing team found the medium firm (6) design to be the most balanced of the three firmness options. You can expect gentle conforming and even overall support from this model. If you need extra reinforcement and minimal cushioning from your sleep surface, we recommend the firm (8) Elite Ultra Hybrid — this model was popular among our back and stomach sleepers weighing more than 230 pounds.

Temperature control proved to be a strong performance area for the Elite Ultra Hybrid during our tests. Thermal sensors detected minimal heat buildup, especially on the two firmest models, and none of our testers reported uncomfortable heat retention. We also found the perimeter stable when testing the mattress for edge support, and the surface was responsive enough to facilitate movement without excessive sinkage or resistance.

Construction Breakdown

The Elite Hybrid’s comfort system consists of gel-infused memory foam over microcoils and transitional polyfoam. These layers provide even contouring to distribute your weight and alleviate pressure along the spine.

Pocketed coils and dense base foam make up the support core. Thicker coils line the perimeter to protect the edges of your mattress from sinkage when you get in and out of bed. These coils are also zoned for extra support beneath your midsection. The cover is composed of Celliant-blend fabric intended to dissipate heat on contact, so the surface should remain cool to the touch at all times.

We tested all three versions of the Endy Hybrid and found each one equipped to meet the needs of different sleeper types. The medium soft (4) model delivers a deep contour for the whole body – side sleepers under 130 pounds can benefit from this close cushioning, but heavier side sleepers and back sleepers of any weight are likely to sink too much. These individuals are better candidates for the medium firm (6) and firm (7) designs, both of which conform to a moderate extent. Stomach sleepers up to 230 pounds may receive adequate support from the medium firm or firm model, but this position typically demands a very firm mattress to prevent neck and lower back strain.

Temperature control is a performance area where all three Endy Hybrid models excelled. A breathable open-cell foam layer on the surface and open coils that promote steady internal airflow help the mattress stay cool and comfortable. The firm model also earned high marks for edge support and ease of movement, while the medium soft and medium firm fared better during our motion isolation and pressure relief tests.

Construction Breakdown

The Endy Hybrid contains a top comfort layer of adaptive polyfoam. This foam has an open-cell composition, allowing air to pass through it more easily, so excessive heat buildup shouldn’t be an issue for most sleepers. The foam layer’s thickness depends on which firmness you choose, and ranges from 1 inch for the firm model to 3 inches for the medium soft.

Medium-density transitional foam lies beneath the comfort layer, creating a cushy buffer between your body and the pocketed coils in the support core. These coils are zoned to deliver more pushback beneath the torso and hips, and reinforced along the perimeter to protect the edges from deep compression. A stretch-knit polyester cover encases the entire mattress.

The Endy Hybrid is competitively priced. Additionally, Endy now offers free ground shipping to customers in the contiguous U.S. in addition to all Canadian provinces. Your order includes a generous 365-night sleep trial. You’ll also receive a 15-year warranty.

The Birch Mattress is one of the most balanced latex hybrids we’ve encountered. Our testers have noted consistent responsiveness and ease of movement across the surface, but also closer contouring and deeper cushioning compared to other beds with latex comfort layers.

The mattress was particularly popular with side sleepers on our team weighing at least 130 pounds, back sleepers between 130 and 230 pounds, and stomach sleepers over 230 pounds. Due to its breathable components, the Birch also performed well during our temperature control tests and displayed minimal heat retention.

Construction Breakdown

A comfort system of moisture-wicking wool over ventilated Talalay latex makes the Birch feel exceptionally cool on the surface. We detected low heat retention when testing the mattress for temperature control, and even the hot sleepers on our team felt comfortable lying on the surface. Pocketed coils promote airflow for added breathability. We also noticed strong responsiveness, which can be attributed to the naturally responsive latex and generous coil pushback. An organic cotton cover encases the mattress.

One appealing aspect of the Birch is its eco-friendly design. A Rainforest Alliance certification indicates rubber trees used to create the latex are sustainably grown, while an eco-INSTITUT certification ensures the material has been evaluated for harmful emissions. Additionally, Birch has been recognized for humane treatment of the sheep used to extract wool in the fire barrier.

Our hands-on tests show the Lull Luxe is a great match for side sleepers who weigh at least 130 pounds and back sleepers weighing up to 230 pounds. The balanced medium firm (6) design should hit a sweet spot for these sleepers, as well as some stomach sleepers under 130 pounds who don’t mind a plush, cushy surface.

The Lull Luxe Hybrid’s thick foam layers absorb movement and prevent motion from spreading, making the mattress a solid bet for couples and co-sleepers. Open-cell and gel-infused foams near the surface and steady airflow through the coil system also help the Luxe Hybrid maintain a comfortable temperature inside and out.

Construction Breakdown

The Lull Luxe Hybrid begins with a layer of gel-infused memory foam quilted to the cover, followed by a comfort layer of adaptive polyfoam. These materials mold closely to the body and form a pressure-relieving cradle without allowing sleepers to sink too much. Dense transitional polyfoam and pocketed coils provide reinforcement and bounce, but overall the mattress does not feel very responsive. A breathable rayon-blend cover encases the Lull Luxe Hybrid.
