The WinkBed is a versatile hybrid mattress available in four firmness levels. The balanced construction and multiple firmness options make the mattress a great choice for a wide variety of sleepers – especially those seeking a combination of surface-level cushioning and strong overall support.

How It Performs

Edge support is one of the WinkBed’s key strengths due to the zoned coils. Temperature control is another highlight, thanks to the breathable Tencel cover and strong airflow throughout the coil support core. These features make the WinkBed a suitable option for couples.

During our tests, the medium firm WinkBed was one of the most versatile models. The mattress earned rave reviews from back and stomach sleepers weighing up to 230 pounds, as well as side sleepers weighing 130 to 230 pounds. Many testers attributed the mattress’ exceptional comfort to its mid-level firmness and ultra-supportive feel. The medium soft model was best suited for side and back sleepers up to 130 pounds, while the firmer models were most beneficial for back and stomach sleepers over 130 pounds.

Construction Breakdown

The four firmness levels of the WinkBed are medium soft (4), medium firm (6), firm (7), and firm (8). The mattress features a Euro-top padded with adaptive foam, which is infused with cooling gel intended to disperse body heat. High-density polyfoam beneath the top layer provides additional contouring and support. The base layer contains pocketed coils arranged in a zoned layout, ensuring extra reinforcement for the midsection and minimal sinkage along the perimeter. The entire mattress is encased in a Tencel cover.

Most WinkBed models share the same basic design, but they vary slightly to produce different firmness levels. Most notably, the medium soft model has an extra polyfoam layer to confer softness. The firmest model, known as the WinkBed Plus, is composed of polyfoam and latex layers on top and a zoned coil base on the bottom.

WinkBed mattresses ship free to the contiguous U.S. Customers may purchase White Glove delivery and old mattress removal as well. The mattress comes with a 120-night sleep trial and lifetime warranty.

• Mixed Reviews on Firmness: While many find the mattress perfectly balanced, there are mixed reviews regarding its firmness. Some users find it softer than expected given its firmness level. While the ‘medium firm’ rating is appropriate by our measurements, the bed does have a ‘cushy’ foam feel that makes for a fairly soft surface feel.

The Helix Midnight Luxe is a hybrid mattress with a responsive feel and a well-cushioned foam surface. This design benefits side sleepers who need a bed that supports the body but also cradles areas with pressure buildup.

How It Performs

The Helix Midnight Luxe has a medium firm (6) feel that should be comfortable for a broad swath of sleepers. With ample contouring from the memory foam, this model is excellent for side sleepers between 130 and 230 pounds and back sleepers under 130 pounds. The foam cushions the shoulders, hips, and spine while the coil system amps up responsiveness. A zoned design in the coils offers extra support for the lumbar region. The responsive surface also makes it easy to change positions.

Construction Breakdown

The comfort system in the Helix Midnight Luxe is made of three foam layers. The top layer is a responsive polyfoam that balances contouring and responsiveness. This is followed by two memory foam layers that cradle the body to support the spine and reduce pressure buildup. The support core is made with coils that are reinforced around the entire perimeter. For the cover, you can choose between Tencel or a GlacioTex Cooling material, which is engineered to regulate temperature.

After delivery, customers have 100 nights to try out the Helix Midnight Luxe with the option to return it for a full refund. A 15-year warranty protects against mattress defects.

The Silk & Snow Mattress is an all-foam bed that offers excellent contouring for sleepers who experience painful pressure buildup. The bed carries an attractive price-point given the quality of its materials, especially compared to other beds in similar price ranges.

How It Performs

During performance tests, we found that the Silk & Snow’s foam layers excelled at relieving pressure buildup in areas like the shoulders, hips, and spine, which exert more pressure on the bed surface during sleep. The foam also absorbed a lot of motion, so our testers barely felt each other’s movements when sharing the bed. This is an asset for couples, especially if you wake easily when your sleep partner moves at night. The bed earned the highest marks from side sleepers who weighed up to 230 pounds, as well as back and stomach sleepers up to 130 pounds.

Construction Breakdown

The mattress features three layers of foam and has a medium (5) feel. It begins with a top layer of memory foam infused with a cooling gel. This foam has a higher density composition than some competing memory foam beds, which generates stronger support. The next layer is made of polyfoam that balances cushioning with support, while the bottom layer is dense and supportive to create a sturdy base for the bed. The removable and machine washable cover is made of a polyester and spandex fabric blend.

Silk & Snow offers free shipping to the contiguous U.S. You can try out the bed for 100 nights and return it within this timeframe for a full refund. The mattress is also backed by a 15-year warranty.

The Saatva Classic is a luxury innerspring model featuring a dual-coil design and multiple customization options. Customers have the option to pick between two mattress heights, with no difference in feel.

How It Performs

During our tests, we found the dual coil system provided excellent relief for sleepers who are susceptible to uncomfortable pressure buildup. Side sleepers, in particular, gave the mattress high marks since this position tends to put pressure on the shoulders and hips. The mattress may also appeal to people who run hot during sleep. The top layer of coils is situated close to the surface, so this layer goes a long way toward promoting airflow and helping maintain a cool sleep surface.

Construction Breakdown

You can choose between three firmness levels: soft (3), medium firm (6), and firm (8). All three models have a Euro-top followed by two thin layers of polyfoam and memory foam, which provide some cushion as well as lumbar support. A transitional layer of individually pocketed minicoils provides extra support while creating minimal motion transfer. Below, the hourglass coil support core has a foam encasement reinforcing the perimeter, helping provide support right up to the edge of the bed. The entire mattress is wrapped in a tufted organic cotton cover with a natural thistle fire retardant.

Saatva offers a 365-night sleep trial and a lifetime warranty. Orders in the contiguous U.S. include free White Glove delivery and old mattress removal.

The Nolah Evolution 15 is a pressure-relieving hybrid mattress that’s available in three firmness levels. You can choose between medium (5), medium firm (6), and firm (8) options, which Nolah has named Plush, Luxury Firm, and Firm, respectively. While materials and specifications vary a bit between models, all three feature several cooling features and a foam comfort system that hugs pressure-prone areas.

How It Performs

Each model features a quilted Euro-top that cushions without affecting the support level. In addition to the AirFoam, the Evolution 15 includes a heat escape gusset, thermal conductive fabric, and a layer of wool and cotton that are all included to help regulate temperature. A carrying handle and non-skid base allow for easy use. The zoned coil layer provides more robust support around your lower back and midsection while allowing more give beneath your shoulders and legs.

Construction Breakdown

The support core is built from pocketed coils that are zoned and reinforced at the edges. A layer of polyfoam rests above the core and prevents sleepers from sinking too deeply into the mattress, even when using the softest model. Proprietary graphite-infused polyfoam called AirFoam gently cradles your body and helps draw excess heat away from you while you sleep.

Six standard sizes are available, as well as a split king size for people who own adjustable beds. Nolah provides a 120-night sleep trial as well as a lifetime warranty, though you can opt out of the free trial for added savings. Free shipping is available to shoppers in the contiguous U.S. and you can choose to add old mattress removal and set up at checkout.

The Leesa Sapira Hybrid is designed with balanced comfort in mind. Thick foam layers over a sturdy support core of pocketed coils allow the mattress to excel in several key performance areas, including pressure relief, edge support, and temperature control — all qualities that are important for couples seeking a new bed.

How It Performs

The Leesa Sapira Hybrid is considered medium firm (6), so sleepers should expect gentle contouring and strong overall support. Among our testers, the mattress received the most positive ratings from side sleepers who weigh at least 130 pounds, and back and stomach sleepers under 130 pounds.

The Sapira Hybrid also scores points for temperature control, thanks in large part to the aerated foam layer and steady air currents flowing through the coil system. Other major strengths include edge support and ease of movement. The responsive coils ensure most people can move across the surface without feeling trapped by the mattress, while the perimeter feels exceptionally sturdy.

Construction Breakdown

The Leesa Sapira Hybrid’s comfort system contains a top comfort layer of polyfoam over a secondary memory foam layer. The polyfoam is punched with large holes intended to promote air circulation near the surface of the mattress. This layer has a lightly responsive feel, whereas the memory foam molds to your body’s contours as you sink into the surface. This creates a feeling of both sleeping “in” and sleeping “on” the mattress.

The Sapira Hybrid also features a transitional layer of dense polyfoam over a pocketed coil system and a foam base layer. The coils are zoned for added reinforcement along the perimeter to provide pushback and reduce sinkage. A knit polyester cover encases the entire mattress.

Leesa offers free ground shipping for customers in all 50 states. Sapira Hybrid orders include a 100-night sleep trial with free returns after a 30-night break-in period, and those who keep the mattress also receive a 10-year manufacturer’s warranty.

Our testers with back pain often benefit from mattresses with cushioning for the spine and robust support to maintain healthy sleep posture. The Bear Elite Hybrid is a hybrid with foam layers that relieve pressure and evenly distribute weight, while a coil system keeps your body on an even plane. With three firmness options to choose from, you can pick the design best suited for your sleep position and body type.

How It Performs

The medium firm and firm options of the Bear Elite Hybrid are easy to move across without sinking or feeling stuck. This can be attributed to a coil system that makes the surface bouncy and reinforces the perimeter, which may appeal to couples who prioritize a responsive mattress for sex. The Celliant-blend and PCM cover effectively keeps the surface cool by offsetting heat retention from the foam layers. Steady airflow through the coil layer provides additional thermoregulation.

The medium model is best suited for side and back sleepers up to 130 pounds, since these sleepers need a fair amount of cushioning to cradle the shoulders, hips, and spine. The medium firm model felt most comfortable to side sleepers over 130 pounds and back sleepers up to 230 pounds. The firm option earned its highest marks from stomach and back sleepers over 130 pounds.

Construction Breakdown

The Bear Elite Hybrid comes in medium (5), medium firm (6), and firm (8) options. All three models begin with a quilted cover and layer of adaptive memory foam. Underneath is a polyfoam transitional layer that acts as a buffer between your body and the coils. These comfort layers vary in firmness depending on which firmness option you choose. Pocketed coils reinforce the sleep surface and strengthen the edges of the mattress. The coils rest on a polyfoam base layer for extra stability.

The cover is made of a proprietary fabric blend that integrates Celliant, a material engineered to absorb your body heat, turn it into infrared energy, and confer it back to you to promote recovery. The cover is also infused with phase change material (PCM) that helps regulate temperature.

Bear’s 120-night sleep trial allows you ample time to test the Bear Elite Hybrid and decide whether it meets your needs. Should you decide to keep the mattress, you’ll also qualify for a lifetime manufacturer’s warranty. Shipping is free for all orders in the contiguous U.S.

The Brooklyn Bedding Aurora Hybrid is a hybrid model available in three different firmness levels. Across all firmness options, the mattress is designed with cooling features that should keep the bed at a comfortable, cool temperature for hot sleepers.

How It Performs

Given its thick foam comfort system, the Aurora Hybrid excels at relieving pressure in areas that are prone to painful pressure buildup at night. During tests, the two softer models earned especially high marks from back and side sleepers under 130 pounds. Side sleepers between 130 and 230 pounds also found these firmness levels comfortable, thanks to the even mix of cushioning for the shoulders and hips and support for the lower back. The firm model appealed most to back and stomach sleepers who weigh over 130 pounds. Hot sleepers found the bed very comfortable, thanks to air circulation through the coils and PCM in the cover.

Construction Breakdown

Shoppers can choose between a medium soft (4), medium firm (6), and firm (7) version of the mattress. All models begin with a top layer of proprietary CopperFlex foam, which conforms to the body and provides targeted relief to areas of the body that need it most. This is followed by a TitanFlex foam layer, which balances additional contouring with a slightly bouncy feel. The medium soft and medium firm options then feature a 1-inch layer of memory foam, which enhances pressure relief, while the firm model uses a layer of VariFlex to give the bed a firmer feel. If you prefer more cushioning from your sleep surface, the optional “Cloud” foam layer can be added to the top of your comfort system for an extra fee.

Underneath the comfort layers is a sturdy coil system zoned to offer stronger support to the lower back while relieving pressure in areas like the shoulders and hips. The cover is composed of a soft fabric infused with TitanCool, a phase change material (PCM) designed to keep the bed surface cool.

Customers receive a 120-night sleep trial with their purchase, and Brooklyn Bedding offers a 10-year warranty with the mattress. The bed ships free within the contiguous U.S.

The following ratings show how suitable this mattress is for different sleeping positions and sleeper weights. These scores are determined by how well the mattress supports and relieves pressure for each sleeper type.

• Firmness Level: The Titan Plus Luxe mattress offers a firm support that is appreciated by those who need it, but may be too firm for many, likened to “sleeping on plywood” by one user.
• Supportive for Plus Size: Specifically designed to be supportive for plus size individuals, many reviewers found the mattress to be supportive and comfortable, helping alleviate back pain.
• Edge Support Issues: Several users reported that the edge support of the mattress is lacking, making it difficult to sit on the edge or causing a feeling of instability.
• Motion Transfer: Some users experienced noticeable motion transfer on the mattress, which could be disruptive for people who share the bed.

• Positive Customer Service Experiences: Many reviewers highlighted excellent customer service, particularly appreciating the easy return and exchange policies when the mattress did not meet their expectations.

Many mattresses that cater to heavy sleepers end up sacrificing some cushioning for support, but the Titan Plus Luxe from Brooklyn Bedding is a notable exception. This hybrid model has a foam and coil design that cushions your body while still offering plenty of sturdiness to keep you well supported.

How It Performs

With an overall medium firm (6) feel, the Titan Plus Luxe felt very supportive during our tests, while still offering pressure relief for areas like the shoulders and hips. If you need a lot of support but have a co-sleeper who favors strong pressure relief, this is a nice happy medium. This design felt comfortable for a wide range of testers on our team, though it was most comfortable for side sleepers who weighed over 230 pounds and back sleepers between 130 and 230 pounds.

Strong coils reinforce the bed’s perimeter, so we found the edges didn’t sag much when we sat on them. Airflow through the coils helps reduce heat retention, so hot sleepers shouldn’t overheat excessively. If you’d like to ensure a cooler surface, you can always purchase the cooling panel.

Construction Breakdown

The surface of the mattress is quilted with an inch of memory foam infused with a cooling gel. This is followed by a thicker layer of TitanFlex foam, which contours to the body but less so than the memory foam. Beneath is a transition layer made of Energex foam with a firmer feel, followed by a thick layer of TitanCaliber coils that generate strong support. For an additional fee, you can add a GlacioTex Cooling Cover. This is made with phase change material that helps keep the surface cool.

The Titan Plus Luxe ships for free and comes with a 120-night sleep trial. The mattress is also backed by a 10-year warranty.

The Birch Mattress is a high-end mattress made with wool, latex, and steel coils. The premium materials offer more comfort than the average hybrid model, and they boast several certifications to ensure the bed is as eco-friendly as it is comfortable.

How It Performs

With a medium firm (6) feel, the Birch is one of the most balanced mattresses we’ve tested in our lab. Most sleepers on our team felt comfortable on the mattress regardless of sleep position or body type. That said, the bed is best suited for side sleepers who weigh at least 130 pounds and back and stomach sleepers up to 230 pounds. The plush wool layers cradled our bodies to relieve pressure buildup in the shoulders, hips, and spine, but the coil system and latex pushed back to generate plenty of support.

The bed excelled at cooling during our temperature neutrality tests. All the materials are naturally breathable, and the cotton and wool excel at wicking moisture. The coils promote plenty of airflow through the bed’s interior, so we recommend this bed for hot sleepers.

Construction Breakdown

The mattress begins with a plush quilted Euro-top and organic cotton cover. Next is a layer of wool that cushions the body and serves as a fire retardant, followed by an additional wool layer. The wool enhances the plushness and regulates temperature thanks to the material’s natural breathability. A Talalay latex layer balances contouring and bounce, while the sturdy steel coils provide sturdy support for your entire body. Extra reinforcement along the longer sides of the bed helps prevent sagging on the edges.

The cotton is GOTS-certified organic, the latex has certification from the eco-INSTITUT, and the entire mattress is GREENGUARD Gold-certified to show it has met rigorous health and safety standards.

The Birch Mattress comes with a 100-night sleep trial so that you can test the mattress at home. It also includes a 25-year warranty. Shipping is free to all 50 states.
