Best Cooling Mattress of 2025

If you’re in the market for a new mattress but aren’t sure about your ideal firmness level, Helix Sleep offers a wide selection of memory foam hybrid models designed for specific body types and sleep positions. We found the Midnight Luxe to be one of the brand’s most well-rounded models. The mattress is designed with a pocketed coil system that promotes steady airflow and helps the mattress maintain a comfortable temperature.

How It Performed

We found the support from the Midnight Luxe’s transitional layer prevented testers’ bodies from sinking too deep into the bed. Between this and the conforming memory foam layers, the mattress relieved pressure while still retaining some bounce, making it a good match for our team’s side sleepers who experience pressure buildup in the shoulders and hips. The pocketed coils provide a supportive base and also allow for steady airflow, reducing heat retention that may be associated with foam layers. Consequently, the Helix Midnight Luxe slept quite cool.

Construction Breakdown

While standard Helix models may appeal to budget-minded shoppers, the Luxe series consists of thicker pillow-top hybrids equipped with extra features to enhance your sleep experience. The Midnight Luxe is the middle-of-the-road option, which our testers rated medium firm (6). The mattress contains two layers of memory foam beneath the pillow-top to give the surface a plush feel. A polyfoam transitional layer provides extra conforming as well as support. The support core is made of zoned pocketed coils, followed by a base layer of high-density foam.

Helix Sleep provides free shipping throughout the contiguous U.S. The Midnight Luxe comes with a 100-night sleep trial and lifetime warranty.

How This Bed Stays Cool

The Helix Midnight combines breathable design elements with cooling technologies to combat heat buildup and help you sleep cool through the night. The bed’s base of pocketed coils provides space for steady airflow through the mattress, allowing excess body heat to flow away from the body.

The Tencel cover is a newer fabric known for its breathability and moisture-wicking qualities. Breathability helps with airflow, while moisture-wicking can draw moisture away from the body to keep you from waking up in a sweat. The Midnight also makes use of gel-infused memory foam to help combat heat retention by drawing heat away from the body.

The Leesa Sapira Chill Hybrid pairs a thick foam comfort system with a sturdy coil base, resulting in a balanced mattress with excellent cushioning for sleepers who prioritize pressure relief. Available in three firmness options, it’s a suitable pick for couples who need a bed that can accommodate a range of sleep preferences.

How It Performs

You can choose between three firmness levels that translate to medium (5), medium firm (6), and firm (7) on our 10-point firmness scale. Regardless of the firmness level you pick, the mattress has a 14-inch profile with substantial foam layers that cradle your body and offer very good pressure relief for areas like the shoulders, hips, and spine. Air circulation in the coils, a gel infusion in the top foam layer, and cooling fibers in the cover all help keep the surface at a comfortable temperature.

Side sleepers in lighter weight categories preferred the softer models while those in heavier weight groups gravitated toward the firmer models. Back sleepers up to 230 pounds generally gave higher marks to the two firmer options, and stomach sleepers in the same weight category gave their highest marks to the firm model.

Construction Breakdown

The Leesa Sapira Chill Hybrid has a polyester blend cover infused with cooling fibers that help mitigate heat retention. Two inches of polyfoam are quilted into the cover for even cushioning across the surface. This is followed by three additional foam layers, one of which is memory foam, that generate close contouring. The layers grow progressively denser to prevent you from sinking into the support core, which contains pocketed coils. The coils are zoned to enhance support in the lumbar area.

Leesa ships mattresses for free to all 50 states. Each bed comes with a 100-night sleep trial and a lifetime warranty.

How This Bed Stays Cool

The Leesa Sapira Chill Hybrid is built with cooling technology from cover to base. Proprietary cooling fibers in the cover help mitigate heat buildup. Air circulates through the pocketed coils, taking body heat with it. Lastly, the Sapira Chill’s memory foam is infused with copper, which is meant to help draw heat away from the body to help it dissipate.

A mattress’s comfort level is a matter of subjectivity, but some beds are designed to feel comfortable for a wide swath of sleepers. We found the Brooklyn Bedding Aurora Luxe is one such mattress. It comes in three firmness levels to accommodate different types of sleepers, and the hot sleepers on our team appreciated the Aurora Luxe’s cooling features.

How It Performed

The Aurora Luxe is designed with comfort in mind – just soft enough to cushion our pressure points, but supportive enough to prevent sagging. All three firmness options excelled at relieving pressure buildup during our testing, which is especially important for side and back sleepers. Sleepers under 130 pounds found the medium soft option most comfortable, while sleepers who weigh over 230 pounds found the best support from the firm bed. The medium firm option is appropriate for many weight categories, depending on your sleep position.

The cover fabric and CopperFlex foam are both infused with TitanCool, a phase change material meant to wick moisture from the body, dissipate heat, and maintain a neutral temperature. The coils also enable air to circulate and keep the bed cool.

Construction Breakdown

The Aurora Luxe is available in medium soft (4), medium firm (6), and firm (7) feels. All options feature a top layer of CopperFlex foam. We noticed this foam conformed to the body but was also slightly responsive. Next is a layer of TitanFlex foam that feels firmer. The medium soft and medium firm versions include a transitional layer of gel-infused memory foam beneath these two layers, while the firm model uses TitanFlex foam for enhanced support.

All firmness options include a support core of pocketed coils that are zoned for extra support to the midsection. You can opt for an additional foam layer in the comfort system. This layer, known as the “Cloud” pillow-top, provides extra cushioning and may make the mattress feel slightly softer compared to models that don’t feature this layer.

Trial, Shipping, & Warranty

Brooklyn Bedding provides free shipping within the contiguous U.S. Customers receive a 120-day sleep trial and are eligible for free returns after a 30-day break-in period. The bed is backed by a lifetime warranty.

How This Bed Stays Cool

The Brooklyn Bedding Aurora Luxe starts strong with pocketed coils that allow for airflow through the bed. Gel infusions in the bed’s foams are designed to help foams sleep cooler. Lastly, the foams and cover are infused with a phase change material – a more recent innovation in the mattress world.

When phase change materials are used in bedding, they acclimate to their surroundings and are designed to draw heat away, store it, and release it. This means that the bed starts the night at the cooler temperature of your bedroom, draws excess heat away from your body, stores it, and sends some of it back to you when you start getting too cold.

Picking the right cooling mattress can be challenging for side sleepers. We’ve found that people who primarily use this position experience pressure buildup along the spine, so they need an adaptive mattress that promotes even alignment and cushions the shoulders and hips. Thanks to a combination of foam layers and breathable components, we think the WinkBed is a good compromise for side sleepers seeking a cool, comfortable, and supportive mattress.

How It Performed

We found the WinkBed to be both plush and robust – a rare combination for mattresses our team has tested. The foam layers molded closely to the body while the coils created a strong support system to prevent our testers from sinking too deeply. Thanks to the range of firmness options, sleepers in most weight categories on our testing team found a model that felt comfortable.

Motion isolation is another area where the WinkBed performed well compared to other hybrid models. The top layers absorbed movement effectively, and the coils didn’t produce much responsiveness. At the same time, the edges felt secure thanks to the zoned coil system, and none of us sank excessively when moving across the surface. Steady airflow through the coils and the moisture-wicking Tencel cover also earned the WinkBed positive marks during our temperature control tests.

Construction Breakdown

The WinkBed is available in four firmness levels: medium soft (4), medium firm (6), and firm (7), as well as the WinkBed Plus option with a firm (8) feel. Standard WinkBed models begin with a layer of polyfoam quilted into the cover, followed by an additional polyfoam layer in the medium soft, medium firm, and firm models. The Plus has a zoned latex layer instead of a second polyfoam layer. We noticed gentle conforming from the quilted polyfoam, resulting in even weight distribution and reduced pressure buildup. The transitional polyfoam layer provides moderate cushioning while serving as a buffer between your body and the support core. The medium soft model includes an extra layer of polyfoam for added cushioning.

As a hybrid model, the WinkBed uses pocketed coils for stability. These coils are designed to move independently from one another, creating a sturdy support system without generating too much bounce or motion transfer. Extra reinforcement along the perimeter helped prevent deep sinkage when our testers got in and out of bed.

Trial, Shipping, & Warranty

WinkBeds offers free ground shipping throughout the contiguous U.S. and a 120-night trial period. All WinkBed mattresses are backed by lifetime warranties.

How This Bed Stays Cool

The WinkBed isn’t packed full of cooling technology or specialized foams. Instead, the bed stays naturally cool with its breathable build. Pocketed coils in the base and micro-coils in the comfort layers allow for tons of airflow through the mattress, drawing excess body heat out of the bed. The breathable cover aids airflow, while the WinkBed’s minimal use of foam creates fewer pockets for heat to get trapped.

Many mattresses that excel at temperature control carry steep price-tags, but the Brooklyn Bedding CopperFlex Memory Foam manages to sleep cool and be affordable at the same time. This all-foam model also excels in key performance areas such as motion isolation and pressure relief.

How It Performed

Evaluations in our Test Lab indicate the CopperFlex Memory Foam is a solid match for side sleepers who weigh at least 130 pounds, back sleepers weighing up to 230 pounds, and stomach sleepers under 130 pounds. People in these sleep position categories who weigh more than the aforementioned groups should consider a firmer mattress.

Motion isolation is a clear strength of the CopperFlex based on our performance tests. The foam layers absorb movement and prevent it from transferring elsewhere on the mattress surface, so this model should be satisfactory for couples and co-sleepers. Temperature control is above average for a memory foam mattress – this can be attributed to the cooling cover and copping fiber infusion in the top memory foam layer.

Construction Breakdown

The CopperFlex’s comfort system contains a top layer of adaptive polyfoam, two memory foam layers, and zoned transitional foam that provides extra support for your midsection. Copper fibers are infused into the first memory foam layer to dissipate heat from the surface and keep you cool. The support core contains two layers of high-density polyfoam. A cover made of GlacioTex cooling fabric encases the mattress.

Trial, Shipping, & Warranty

Shipping is free of charge within the contiguous U.S. Brooklyn Bedding offers a 120-night sleep trial for each CopperFlex Memory Foam purchase. After testing the mattress for at least 30 nights, you may return it for a full refund minus a small fee. Conversely, if you keep the mattress, your purchase is covered under a lifetime manufacturer’s warranty.

How This Bed Stays Cool

Memory foam mattresses, particularly all-foam mattresses, struggle with heat retention since memory foam conforms to the body as it absorbs heat. The Brooklyn Bedding CopperFlex uses copper-infused foam and a heat-dissipating cover to combat the heat buildup that’s common with memory foam beds. Both cooling technologies are designed to help the bed stay cool to the touch and draw heat away from your body as you sleep.

Since uneven support and excessive sinkage can exacerbate pain from poor sleep posture, some sleepers require a mattress with extra reinforcement for their bodies that keeps them on an even plane. The Saatva Latex Hybrid has a luxury latex-over-coil design that delivered outstanding stability during our testing without sacrificing comfort or pressure relief.

How It Performed

The Latex Hybrid’s responsiveness and medium firm (6) feel best suited our back and stomach sleepers weighing between 130 and 230 pounds, but most sleepers who use these positions should feel comfortable. The latex offers gentle cradling to relieve pressure points, while the coils keep the body from sinking excessively.

Temperature control was one of the mattresses main strengths. The breathable cover and comfort materials naturally retain less heat, and the coil system ensures steady internal airflow. As a result, our heat guns detected minimal heat retention during testing. We also found the mattress to be a great choice for couples who prefer a bouncier surface for sex. Couples should feel comfortable moving across the full surface with little to no sinkage along the edges.

Construction Breakdown

A layer of GOTS-certified organic wool gives the surface a bit of cushioning while acting as a natural fire barrier. Underneath is a layer of zoned Talalay latex that offers enhanced support to the lower back while cradling pressure points in the hips and shoulders. This layer also prevents your body from sinking too deeply into the coils.

Zoned pocketed coils make up the support core. Thicker coils are zoned underneath the midsection to prevent uncomfortable sagging and help you maintain healthy sleep posture. The coils rest on a base layer made from a blend of organic cotton and GOTS-certified organic wool. The mattress is encased in a breathable organic cotton cover.

All Saatva customers in the contiguous U.S. qualify for free White Glove delivery, which includes full assembly in your home and removal of your old mattress. Comparatively, most online mattress brands charge at least $100 for this service. Your purchase also includes a 365-night sleep trial and a lifetime warranty.

How This Bed Stays Cool

The Saatva Latex Hybrid combines multiple naturally cooling elements in its construction to keep hot sleepers comfortable through the night. Cotton and wool are both breathable materials that support the ample airflow through the bed’s pocketed coils. Wool also aids in wicking moisture away from the body, keeping sleepers from waking up in a sweat. Latex foams naturally sleep cooler than polyfoam and memory foam, partially because latex doesn’t hug as closely to the body when you lay on it.

The Nolah Evolution 15 is a hybrid mattress that combines the contouring features of foam with the strong support of a coil system. The result is a bed that excelled in our pressure relief tests, making it ideal for sleepers with back pain and other people who experience painful buildup at night.

How It Performed

The Evolution 15 earned positive reviews from testers who normally run hot during sleep. The foam layers are engineered to draw heat away from the body, and the coil system enables air to circulate. The bed is available in three firmness options, making it suitable for various sleep positions and sleep preferences. The side and back sleepers on our team preferred the plush and luxury firm options, which translate to medium (5) and medium firm (6) feels, respectively. Stomach sleepers appreciated the firm (8) option, since this sleep position requires a flat, supportive surface for proper spinal alignment.

Construction Breakdown

At 15 inches thick, the Nolah Evolution 15 is a high-profile mattress with an adaptive comfort system. The Euro-top cover is quilted with foam, followed by a comfort layer of proprietary AirFoamICE foam. When our testers were lying on the bed, they found these two comfort layers offered above-average cushioning for a hybrid. Next is a firmer layer of polyfoam, which provides moderate contouring but also buffers you from the support core. Beneath the foam is an 8-inch pocketed coil system that offers targeted support to different areas of the body.

Trial, Shipping, & Warranty

The Evolution comes in all six standard sizes, as well as a split king size for adjustable beds. Nolah ships mattresses for free within the contiguous U.S. Customers receive a 120-night sleep trial and may return the bed for a full refund after an initial 30-day period. The Evolution 15 comes with a lifetime warranty.

How This Bed Stays Cool

The Nolah Evolution 15 uses a combination of proprietary foam layers and pocketed coils to deliver comfort and reduce heat buildup. The foams are designed to help dissipate heat through the airflow provided by the bed’s thick pocketed coils.

Most mattresses that earn high ratings in our motion isolation tests have adaptive foam layers, and this can lead to an uncomfortable sleep temperature if the cushioning layers absorb excess heat. With the Bear Elite Hybrid, you get the best of both worlds. Thick foam layers prevent movement transfer when your partner changes positions at night, but we found the specialized cooling cover facilitates airflow while you sleep.

How It Performed

Elite Hybrid buyers choose from three firmness levels. During our tests, the Luxury Plush – a medium (5) model – earned the most favorable ratings from side and back sleepers weighing less than 130 pounds. This design offers the closest contouring and may sink a bit too much for sleepers who weigh more. The Luxury Firm (6) model was most popular among our side sleepers weighing 130 to 230 pounds and back sleepers weighing up to 230 pounds. The most balanced of the three, this model cushions and supports the body in equal measure. Lastly, the Firm (8) model provided excellent reinforcement for side sleepers weighing more than 230 pounds, as well as back and stomach sleepers weighing at least 130 pounds.

Temperature control is a defining trait of this mattress. This can be attributed to the Celliant-blend cover, which releases heat from the surface, as well as steady air circulation through the coil system and the breathable, copper-infused memory foam comfort layer. The Elite Hybrid’s other strengths vary by firmness level. The two softest models performed well during our pressure relief tests, while the two firmest options feel more secure along the perimeter and don’t sink excessively when you move across the surface.

Construction Breakdown

A memory foam comfort layer and polyfoam transitional layer make up the Elite Hybrid’s comfort system. The memory foam is infused with copper, which has natural cooling properties. The polyfoam is divided into five different firmness zones. We noticed that this zoned design enhances support around the midsection – where people tend to carry extra weight – while gently cradling the head, shoulders, and legs.

The Elite Hybrid’s support core consists of pocketed coils over a high-density polyfoam base layer. Extra-strength coils along the perimeter provided pushback and decreased sinkage when our testers lied along the edges of the mattress or got in and out of bed. A cover made of Celliant-blend fabric encases the mattress. Celliant is engineered to dissipate heat on contact, resulting in a sleep surface that feels cool at all times – even on exceptionally hot or humid nights.

How This Bed Stays Cool

The Bear Elite Hybrid’s construction uses natural breathability and engineered cooling technologies to fight heat retention. A base of pocketed coils provides steady airflow through the bed, drawing out excess body heat. The bed’s use of a Celliant-blend cover adds breathability. Lastly, the memory foam in the comfort layer is infused with copper to aid in drawing heat away from the body.

If you sleep with a partner, a mattress that absorbs movement and minimizes motion transfer can help you both get the rest you need without disruptions in the middle of the night. Casper’s Snow Max is constructed with three layers of memory foam in its comfort system. Although this is a hybrid mattress with a coil support core, our tests show the surface remains tranquil and movement-free even when one person changes positions or gets on and off of the bed. Cooling materials and zoned transitional foam add to the appeal for side sleepers.

How It Performed

The Casper Snow Max is medium soft (4). As such, the mattress earned strong ratings from side sleepers on our testing team who weigh up to 230 pounds – those under 130 pounds were particularly impressed. Some of our lighter back and stomach sleepers also felt comfortable on the mattress, but most needed a firmer bed to feel adequately supported. Since the Snow Max is so plush and adaptive, it isolates motion and relieves pressure better than most competing foam hybrids on the market. Proprietary “HeatDelete” bands and phase change material infused into the top layer also help dissipate heat away from the sleep surface and keep you cool throughout the night,

How This Bed Stays Cool

Phase change material engineered to capture and release heat is infused into the top memory foam layer, so the surface shouldn’t absorb too much warmth from your body. Another cooling element is HeatDelete specialized graphite bands embedded between the first and second layers. These bands also draw heat away from the mattress. You may notice some heat buildup on the foam layers, but this shouldn’t be excessive or interfere with your sleep. A breathable knit cover encases the mattress for added thermoregulation.

Construction Breakdown

The Snow Max’s first layer is composed of adaptive memory foam with a cooling phase change infusion. Two more memory foam layers are included in the comfort system, and both are zoned to feel firmer and more supportive around your midsection. These layers help ensure side sleepers between 130 and 230 pounds don’t sink too deeply into the mattress. Pocketed coils and high-density base foam make up the support core. The coils are reinforced along the perimeter to push back against your weight when you lie close to the edges or get in and out of bed – but that said, you may still notice some sinkage due to the bed’s softer feel. A knit polyester cover encases the mattress.

Trial, Shipping, and Warranty

Casper offers free ground shipping to customers in the contiguous U.S. Additional delivery fees apply to Alaska, Hawaii, and Canada. Your Snow Max purchase includes a sleep trial that runs for 100 nights. If you decide to keep the mattress after the return period ends, it’s further covered under a 10-year manufacturer’s warranty.

Foam hybrids aren’t known for sleeping especially cool, but some models integrate breathable and moisture-wicking materials into their designs and regulate temperature well as a result. Take the DLX Premier Hybrid, which features a layer of cooling viscose fibers quilted into the cover. This helps ensure a cool surface even during hot or humid times of the year, and steady air circulation through the coils also helps with temperature control.

How It Performed

During hands-on tests, the medium soft (4) Premier Hybrid earned stellar ratings from our side sleepers weighing up to 230 pounds — they appreciated the deep contouring and pressure relief of this model. Back and stomach sleepers over 230 pounds preferred the sturdy support of the firm (8) model. Everyone else on the testing team gave their highest marks to the medium firm (6) mattress, which delivers a nice balance of cushioning, reinforcement, and bounce.

The two softer models performed well during our motion isolation and pressure relief tests. These findings can be attributed to the thick foam layers and close, even conforming. The firm mattress fared better for testing categories like ease of movement and edge support. We were impressed with all three during temperature control tests, as the cooling viscose fibers quilted to the cover have a noticeable impact on how cool the surface feels.

Construction Breakdown

The Premier Hybrid’s topmost layer consists of shredded viscose fibers. Viscose is a fabric derived from plant matter with excellent cooling and moisture-wicking properties. Three foam layers make up most of the comfort system. Each layer is progressively denser from top to bottom, creating a plush surface that molds to your figure and underlying layers that push back against your weight.

Pocketed coils and dense base foam provide excellent overall stability for the mattress. Thicker coils along the perimeter help reduce sinkage when you get in and out of bed or sleep close to the edges. A knit polyester cover encases the mattress. At 14 inches thick, the Premier Hybrid is considered a high-profile model.

In addition to the three standard firmness options, you can also choose a split mattress with a unique feel on each side if you and your partner have different firmness preferences.

Trial, Shipping, & Warranty

DLX offers free ground shipping throughout the contiguous U.S. and a 120-night sleep trial with each purchase. Those who keep their mattress after the return period ends also receive a lifetime warranty against manufacturing defects.

How This Bed Stays Cool

The DLX Premier Hybrid starts the fight against heat buildup with breathable, moisture-wicking viscose fibers quilted into the cover. The fibers contribute to the bed’s ability to carry body heat away via airflow, while keeping the bed dry. Heat absorbed by the foam is pulled away through the bed’s coil system.

Mattresses with foam layers typically trap body heat since they adapt so closely to the body. The Layla Hybrid pairs cooling technology with steady airflow through the coil system, earning it high marks in our temperature control tests.

How It Performed

The mattress has a reversible design with a different feel on each side: medium soft (4) and firm (7). Most of our testers found a side that felt comfortable, regardless of their sleeping positions or body types. The softer side’s thick cushioning earned its highest ratings from our side sleepers weighing up to 230 pounds, as well as back and stomach sleepers weighing under 130 pounds. Meanwhile, the firmer side offered even contouring enjoyed by back and stomach sleepers weighing at least 130 pounds.

Both sides earned balanced reviews across our testing criteria with only slight differences in performance. The softer side’s thicker comfort system absorbed more motion, while the firmer side slept slightly cooler. Both excelled in our edge support tests, thanks to the reinforced perimeter.

Construction Breakdown

Both sides feature a mixed-foam comfort system, but the softer side’s foam layers are slightly thicker than on the firmer side. They begin with an adaptive memory foam layer that closely contours to the body to relieve pressure. This layer is infused with copper gel meant to conduct and dissipate heat. Underneath is a polyfoam transitional layer that acts as a buffer between the comfort system and the coils.

Pocketed coils make up the shared support core, offering targeted support to the midsection to reduce uncomfortable sagging. A reinforced perimeter prevents you from sinking when lying or sitting near the edges. The cover is made from a stretchy polyester, rayon, viscose, and poly-lycra blend.
