Human body temperatures naturally increase and decrease over the course of a single day. Some studies suggest your temperature changes during different stages of your sleep cycle, reaching its lowest levels as NREM sleep begins. This decrease in body temperature tends to promote better sleep, while higher temperatures can interrupt the sleep cycle. As a result, cooling mattresses made with breathable components may help you sleep better and longer.
Some people naturally run hotter than others in bed. For these sleepers, a cooling mattress can make the difference between a good night’s sleep and a night full of sweaty tossing and turning. The materials used in comfort layers, support cores, and cover fabrics can all play a role in how well – or poorly – a mattress regulates temperature. To choose our top picks, we evaluated each mattress specifically for breathability and temperature control, but also took additional factors into account such as quality of construction and expected lifespan.
Our top picks for the best cooling mattresses are described in detail below. Because different components can sleep cool, these picks cover a wide range of mattress types. Further down, we’ll outline which mattresses are best for hot sleepers based on individual factors like body type and primary sleep position.

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. Each of these mattresses is constructed with a pocketed coil system that promotes steady airflow and helps the mattress maintain a comfortable temperature.
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 middle of the road option here is the Helix Midnight Luxe, which is designed for a medium firm feel that suits most sleepers weighing up to 230 pounds.
The Helix Midnight Luxe contains two layers of memory foam, one of which lies beneath the pillow-top to give the surface a plush feel. A polyfoam transitional layer provides extra conforming and also supports your body to prevent sinkage. This combination of foams allows the mattress to relieve pressure while still retaining some ‘bounce’.
The support core is made of pocketed coils. In addition to providing a supportive base, coils allow for steady airflow and don’t trap body heat like foam does. Consequently, the Helix Midnight Luxe sleeps quite cool. A base layer of high-density foam offers added reinforcement.
The Midnight Luxe and other Luxe hybrids cost a bit more than standard Helix models, but all have reasonable sticker prices compared to the average hybrid. Helix Sleep also provides free shipping to all 50 states. The Midnight Luxe comes with a 100-night sleep trial and 15-year warranty.
SleepFoundation readers save $200 on a DreamCloud mattress + get $399 in free accessories
As a memory foam hybrid mattress, the DreamCloud provides the pressure relief and notable contouring of memory foam without the traditional problem of trapping heat. The bed’s support core of individually-wrapped coils allow for plenty of cooling airflow throughout the mattress. A gel-infused layer of memory foam in the comfort system draws excess heat away from the body, allowing it to dissipate instead of building up through the night.
The DreamCloud combines layers of high-quality memory foam and polyfoam with a robust base of coils to provide a balanced sleeping experience. Comfort layers of polyfoam and gel-infused memory foam provide a significant amount of pressure relief and contouring, while the breathable bed of coils keeps any part of the body from sinking in too far. As a result, sleeping on the DreamCloud feels like a combination of sleeping “in” and “on” the mattress.
The bed’s coil core and medium firm (6) feel give it a versatile blend of cushioning and strong support, making it a comfortable option for almost any kind of sleeper. Co-sleepers will appreciate the DreamCloud’s ability to satisfy different sleeping preferences, as well as its notable degree of bounce and edge support. The bed’s high-quality construction and performance come at an affordable cost compared to the price of an average hybrid model on the market.
The DreamCloud ships for free to the contiguous U.S., with paid delivery available for Alaska and Hawaii. The mattress is backed by a significantly lengthy 365-night sleep trial that starts after a 30-day break-in period, further adding to its value. After that, the bed is covered by a limited lifetime warranty.

Saatva’s flagship mattress, the Saatva Classic, keeps hot sleepers cool thanks to steady airflow through its coil layers. The mattress is a hybrid innerspring mattress with a transitional layer of pocketed coils and a support layer of bonnell coils. Because of the two coil layers, the Saatva Classic feels springier and doesn’t isolate motion as well as most all-foam mattresses do. The mattress comes in 11.5 and 14.5-inch thickness options.
The Saatva Classic is available in three firmness levels, so there are options for people of all body weights and position preferences. All Saatva Classic mattresses have polyfoam and memory foam comfort layers, and the soft option comes with an additional polyfoam layer. As a result, the soft option is the most conforming, while the other two firmness options have a little bit of “hug,” but feel more responsive.
Shoppers interested in ethical consumption are drawn to the Saatva because it’s made in the US using eco-friendly materials. The coils are recycled steel, the polyfoam meets CertiPUR-US standards, and instead of a chemical flame retardant, they use natural thistle pulp.
Saatva offers a 180-night sleep trial and 15-year warranty. All Saatva mattresses are delivered with free white glove delivery service, which means Saatva will assemble your new bed for you right where you want it.
Best Pressure Relief
SleepFoundation.org readers get 30% off mattresses + 2 FREE luxury pillows ($250 Value) . No code necessary.
The GhostBed Luxe is a mixed-foam bed that provides excellent contouring for people in the market for beds that alleviate pressure buildup. The contouring is balanced out with denser foam in the base layer, making this a good option for sleepers who weigh up to 230 pounds and are seeking foam beds with extra support.
The comfort layer is made of a memory foam that conforms evenly to the body, followed by a transitional layer of Ghost Bounce polyfoam that offers moderate contouring but also a latex-like responsiveness that generates more support than memory foam. Beneath is a support core made of high-density polyfoam, which stabilizes the bed and promotes durability. The cover is padded with a thin layer of memory foam to enhance the plush feeling on the surface. With a medium (5) firmness level, the bed absorbs motion very efficiently, which can help prevent sleep disruptions when partners move at night.
Side sleepers will find the GhostBed Luxe quite suitable, since this sleep position typically requires a bed that cushions the shoulders and hips while also providing sufficient support for healthy spinal alignment. Hot sleepers should find the bed quite comfortable compared to other foam models. The cover is made of proprietary Ghost Ice fabric, which is a polyester and viscose blend that relies on phase change technology to stay cool through the night. The cover also features a cooling fiber that is meant to promote air flow, while the memory foam comfort layer is infused with a cooling gel.
GhostBed provides free shipping within the contiguous U.S. The bed is backed by a 25-year warranty and a 101-night sleep trial. After an initial 30-day break-in period, customers may return the bed during the trial for a full refund.
Get $399 worth of free accessories and a free Google Nest Hub with Sleep Sensing with every Nectar Premier Copper purchase. Use checkout code: sleepfoundation
Nectar offers an array of memory foam beds, but the Premier Copper stands out for its higher profile and enhanced cooling properties compared to other all-foam models. The thick comfort layer makes this bed a top choice for those who prioritize plush, comfortable sleeping surfaces.
The mattress is 14 inches thick with an all-foam construction. The quilted cover contains copper fibers meant to draw heat away from the body.

Next is a thin layer of firmer transitional polyfoam, followed by a 9-inch base layer of high-density polyfoam that stabilizes the mattress.
The memory foam layer conforms closely to the body, resulting in excellent pressure relief and motion isolation. Meanwhile the denser polyfoam layers provide adequate reinforcement, especially for an all-foam bed. The balance of contouring and support makes this bed a solid pick for side sleepers, who typically need cushioning in the shoulders and hips but still require support for the lower back.
Nectar ships free of charge within the contiguous U.S. The mattress comes with a generous 365-night trial and a limited lifetime warranty.
Best for Back Pain
Take $300 off a WinkBeds Mattress. Use Code: SF300
The WinkBed is a hybrid mattress that comes in medium soft (4), medium firm (6), and 2 firm levels (7-8). The soft, medium, and firm options contain a 7.5-inch pocketed coil support layer and microcoil and polyfoam comfort layers. Airflow through the coil layers keep the bed cool. Plus, the polyfoam comfort layers are infused with gel, which adds to the bed’s temperature neutrality.
Microcoils in the WinkBed give the mattress a springy, responsive feel. Although the WinkBed contains foam, it isn’t the best option for sleepers who want a bed they can sleep “in” rather than “on.” The WinkBed Plus is constructed differently than the other firmness options, but it also has a responsive feel due to a latex comfort layer.
Since the WinkBed comes in four firmness levels, there are options for people of all body weights. The WinkBed Plus provides an ultra firm option geared toward sleepers weighing over 300 lbs. The other three WinkBed firmness options will appeal to different sleepers based on their body weights and personal preferences.
The WinkBed mattresses rate average or above in most categories, such as durability, motion isolation, pressure relief, and off-gassing. In terms of edge support, the WinkBed firm and WinkBed Plus have stronger edges than the soft and medium options.
WinkBed mattresses are made in the US and ship free to contiguous US locations. They come with a 120-night sleep trial and a lifetime warranty.
Best for Active People
Get $100 off a Zoma Mattress. Use Code: SF
Athletes and other active people – as well as those with demanding jobs – often need a mattress that will aid with physical recovery and help them wake up without aches and pains. The Zoma Mattress is specifically designed with these sleepers in mind. A comfort layer of proprietary Triangulex memory foam feels firmer beneath areas where people generally carry more weight, such as the torso and hips, and softer for lighter areas of the body. This ensures most people can lie comfortably without sinking or experiencing excessive stiffness.
All-foam mattresses have a less-than-ideal reputation when it comes to temperature control, but the Zoma Mattress is a notable exception. The Triangulex layer is infused with cooling gel meant to draw heat away from your body, while the cover is made from breathable material that promotes consistent airflow. Anyone who normally finds all-foam beds too warm should consider this mattress.
Sleepers should expect close yet even contouring from the Zoma Mattress. Its feel is medium (5), making it best-suited to side and back sleepers who weigh up to 230 pounds. The all-foam construction may also be helpful for anyone who frequently wakes up due to their partner’s movements. The foam layers absorb movement and significantly reduce transfer across the surface, and the mattress is also completely silent when in use.
The price-point for this mattress is very approachable and Zoma offers free ground shipping anywhere in the contiguous U.S. The company’s sleep trial spans 100 nights in length, and those who choose to keep the mattress also receive a 10-year warranty against structural defects.
Best for Side Sleepers
Get $160 off a Layla Memory Foam Mattress + 2 free memory foam pillows with code: SLEEPFOUNDATION
As a flippable mattress, each side of the all-foam Layla has a different firmness level. The top memory foam layers on both sides of the mattress are infused with copper, which promotes cooling. The Layla stays more temperature neutral throughout the night than most all-foam beds, which tend to trap heat. The Layla Mattress works well for light and average-weight sleepers, but heavier sleepers might find that they need more firmness and support.
The Layla Mattress gives sleepers the classic memory foam feel. It “hugs” the body, and is a good choice for people who like to sink “in” rather than float “on” their mattress. Sleepers who prefer a responsive, springy mattress won’t prefer the Layla.
Like many foam mattresses, the Layla isn’t the best when it comes to edge support. Sleepers might find they can’t use the full surface of the bed because of sinking edges. The Layla does isolate motion well, however, and is virtually silent. Couples who share a bed will not be bothered by their partner’s movements when on the Layla.
Layla ships their mattresses for free to the contiguous US, and for a fee to Alaska, Hawaii, and Canada. All purchases come with a 120-night sleep trial and a mandatory two-week break-in period. After the first two weeks, customers may return their mattress without penalty. Layla also offers a lifetime warranty with their mattresses.
Best for Hip Pain
Get an additional $30 off the Nolah Signature Mattress for total savings of $730 with code: SF830
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 offers excellent pressure relief for side sleepers and any other sleepers who experience pressure build-up at night.
At 15 inches thick, the Nolah Evolution 15 is a high-profile bed with a plush comfort system. The Euro-top cover is quilted with foam, followed by a comfort layer of proprietary AirFoamICE foam and a firmer layer of polyfoam. Beneath the foam is an 8-inch pocketed coil system that offers targeted support to different areas of the body.
The Nolah Evolution 15 is a good option for people who run hot during sleep. The foam layers are specially 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. Side and back sleepers may prefer the plush and luxury firm options, which translate to medium (5) and medium firm (6) feels respectively. Stomach sleepers will likely appreciate the bed’s firm (8) option, since this sleep position requires a flat, supportive surface for proper spinal alignment.
Nolah ships mattresses for free within the United States. Customers receive a 120-night sleep trial and may return the bed for a full refund after an initial 30-day period. The mattress comes with a lifetime warranty.
SleepFoundation readers get $400 off a Birch Mattress.
The Birch Mattress is a hybrid bed made from high-quality organic materials. With a medium firm (6) feel, the mattress offers excellent support as well as responsiveness for sleepers who need an even balance between the two.
The mattress is constructed with Talalay latex that cushions pressure points but also provides enough pushback to lend support and prevent excessive sinkage. A core of pocketed steel coils further enhances contouring performance while providing a supportive, durable base. The bed is topped with a layer of wool that creates a plush surface, as well as a wool and rayon layer that acts as a fire barrier. The bed is encased in a cotton cover with organic certification from the Global Organic Textile Standard. The latex is also certified by the Global Organic Latex Standard, making this a strong option for shoppers who are looking for a mattress with verified organic sourcing.
Side sleepers will find the mattress quite suitable, since this sleep position requires a bed that cushions the shoulders and hips while supporting the lower back. Back sleepers will also benefit from the balance of support and cushion. If you tend to overheat during sleep, the breathable latex should help keep you cool. The coil core also allows air to circulate and cool the mattress down at night.
Birch provides free shipping throughout all 50 states. The bed comes with a 25-year warranty and 100-night sleep trial, though mattresses will not qualify for a free return until you’ve completed a mandatory 30-day break-in period.
Get $150 off an Eight Sleep Mattress. Use Code: FOUNDATION150
The Eight Sleep Pod is an all-foam smart mattress that allows sleepers to program the bed to certain temperatures at set times. The Eight Sleep Pod is constructed with a grid of tubes and a pump that must sit next to the bed. The pump pushes water of adjustable temperature through the grid, either cooling or heating the mattress.
Sleepers who want a very precise sleep environment will be delighted by the precision the Eight Sleep Pod offers. Temperature settings range from 55 to 115 degrees Fahrenheit, and different temperatures can be set for each side of the bed. Sleepers can also allow the bed to dynamically adjust the temperature throughout the night on its own.
Since the Eight Sleep Pod only comes in one firmness level, the mattress won’t work for everyone. Sleepers at the high and low ends of the body weight scale might find themselves needing more or less firmness, especially side sleepers. Average-weight sleepers are most likely to find a pleasant mix of support and cushion in this bed.
The Eight Sleep Pod runs on the higher end of the price scale because of its high-tech features. Being able to control the bed from a smartphone through an app costs an additional yearly app subscription.
The Eight Sleep Pod is manufactured in the US and comes compressed in a box. Customers have a 100-night sleep trial during which they can try out the bed risk-free. The Eight Sleep Pod warranty lasts 10 years.
We’ve tested hundreds of mattresses in our Sleep Foundation lab so that we can provide you with options that have been thoroughly researched and vetted. Our team is made up of sleep product experts from a wide variety of weight groups and sleeper types. Having a diverse testing team helps us better predict how mattress performance will change from person to person.
To test each of our top picks for temperature neutrality, we use a combination of technology and in-person trials. We perform a series of body tests that allow us to gauge how much heat a bed’s materials retain, as well as the degree of airflow the mattress allows around the body. Additionally, we use a thermal camera and laser thermometers to determine how much heat is absorbed into a mattress.

Many people tend to “sleep hot,” or notice themselves wake up in the middle of the night feeling hot and sweaty. Some mattresses exacerbate this problem, while others ease it. Hot sleepers might want to seek out a cooling mattress to help them stay asleep throughout the night.
The term “cooling mattress” is used by many mattress manufacturers to indicate that there is something about the mattress’s construction meant to keep sleepers cool during the night. There are many ways in which a mattress can help you sleep cool. The term “cooling mattress” doesn’t refer to any single particular mattress part or system.
Finding a cooling mattress might be your top priority, but you’ll also want to consider other mattress features while shopping. A mattress that keeps you cool isn’t worth much if it causes you discomfort, or isn’t in your price range.
Mattress companies can make many claims and use overblown language when describing their mattresses. Instead of falling for marketing fluff, look past the fancy copywriting to determine what features the mattress has, and if it will meet your needs.
There are multiple types of mattresses sold in the current mattress market. Different types of mattresses are able to keep sleepers cool throughout the night to varying degrees. Generally, mattresses that fall under each category are constructed similarly and share many of the same features.
Of course, there is still plenty of variation within each mattress type. Quality of materials, construction methods, and additional features of specific models will affect how good a particular mattress is for you.
Definition: A hybrid mattress combines aspects of multiple other mattress types. Most hybrid mattresses have a pocketed coil support core layer and comfort layers consisting of polyfoam, latex, or a mixture of materials. The feel of a hybrid mattress can vary quite a bit depending on the comfort layers’ material and thickness.
Highlight: The coil support layer in a hybrid mattress allows airflow through the bed, which helps cool sleepers by reducing the amount of heat trapped in the bed. As a result, most hybrids are fairly temperature neutral. Thick memory foam comfort layers could cause a hybrid mattress to trap heat, however.
Definition: Foam mattresses, also called all-foam or mixed-foam mattresses, are constructed with different types of polyfoam as both the support core and comfort layers. Many sleepers prefer foam mattresses because of the “hug” they generally give the body. The conforming properties of memory foam can relieve pressure and ease pain.
Highlight: Since foam mattresses can trap heat, mattress manufacturers often add in materials with cooling properties. For example, covers with phase-change material absorb body heat and transform it to a cooler temperature. Gel, copper, graphite, and charcoal are all infused into polyfoam comfort layers with the intention of cooling.
Definition: Innerspring mattresses also contain a coil support core beneath comfort layers made of polyfoam, latex, or other material. They differ from hybrid mattresses in that the comfort layers are thinner, and the support core makes up the bulk of the mattress’s thickness. As a result, innerspring mattresses usually feel bouncier and less conforming.
Highlight: One benefit of innerspring mattresses is that they tend to be naturally cooling due to airflow through their coil layers. Even innerspring mattresses that contain memory foam are cooling since the foam layers are relatively thin. Also, innerspring mattresses are generally less expensive than hybrid and all-foam options.
Definition: Latex has been created from the sap of rubber trees, and it relieves pressure while giving mattresses a springy feel. Some latex mattresses contain only latex in both the support core and comfort layers. Other mattresses incorporate latex layers with other materials, such as coils and polyfoam.
Highlight: Many manufacturers aerate their latex mattress layers, or drill holes into them, to allow for increased airflow. As air flows through the latex layer, body heat is dispersed so the sleeper stays cool. Generally, Talalay latex is more temperature neutral than Dunlop, but both types can be aerated.
Definition: Airbeds contain air chambers that can be inflated or deflated to increase or decrease the mattress’s firmness level. Some airbeds allow different firmness levels on each side, which could appeal to couples. Note that an “airbed” is a long-term use mattress and doesn’t refer to inflatable mattresses used temporarily for camping or traveling.
Highlight: Airbeds are generally cooling due to their air chambers, making them a good choice for people who sleep hot. Some people report that certain airbeds can become too cool, however. Airbeds with thicker comfort layers will be less likely to have this problem.
Mattresses are constructed with a variety of materials. Some make mattresses more cooling and breathable, while others trap heat. People who sleep hot need to understand which mattress components are most cooling, so they know what to look for when mattress shopping.
Your mattress isn’t the only thing you should focus on when trying to find ways to sleep cool. Instead, consider your entire sleep environment. Many mattress and sleep accessories can help or hinder your efforts toward temperature neutrality.
Figuring out the ideal sleep temperature for your body is a step you can take toward a better night’s sleep. Then, opt for bedding items that will help support your goal of staying cool throughout the night.
There is no single sleep temperature that’s ideal for all people. Experts suggest that most adults’ ideal sleep temperature lies is around 65 degrees Fahrenheit. There are, of course, many people who fall outside of the norm.
Some people will find they prefer a warmer room, while others who sleep hot might find they need their bedroom even cooler. Individuals can experiment with different sleep temperatures to see what feels most comfortable to them.
The sheet set you choose can greatly impact how warm or cool you feel throughout the night. Some sheets, such as those made of flannel, fleece, and heavyweight cotton, are designed to insulate and retain heat. These sheets aren’t a good option for people who sleep hot.
Other sheet types are more cooling, such as those made from lightweight cotton, linen, and Tencel lyocell. Lightweight cotton sheets are known for their breathability. They are often available in two weaving patterns: percale and sateen. Both are known for breathability, but percale is more of a crisp fabric while sateen feels smoother.
Linen is known as an exceptionally cool fabric, but it can feel rough to the touch. For that reason, manufacturers often pre-soften linen sheets, or create sheets that are a linen-cotton blend. Tencel lyocell is a fiber made from wood pulp that is naturally moisture-wicking and cooling. Most “bamboo” sheets are made from bamboo-derived lyocell.
Some cooling sheets contain synthetic cooling materials, such as Coolmax fabric or Outlast fibers. Coolmax fabric is a moisture-wicking and breathable polyester. Outlast fibers are temperature-regulating phase change materials that can be combined with other fibers and woven into fabric.
There are many cooling pillows available today. If a traditional down or polyester pillow feels too warm, try a cooling pillow made of memory foam or latex. To make memory foam and latex more cooling, manufacturers either aerate the pillows to increase airflow, or infuse them with gel or other cooling materials.
Cooling pillows with air or water chambers are also available for sleepers needing to cool down at night. These are usually higher-priced, but effective.
Some blankets increase body heat, while others cool. Blankets made of wool, down, fleece, cashmere, and heavy cotton are the warmest and should be avoided by hot sleepers looking to cool off.
Lighter, thinner blankets are cooler than heavier, thicker blankets. Naturally cool blankets are often made of lightweight cotton, a cotton blend, Tencel lyocell, and linen. All of these fabrics are breathable and less likely to trap body heat.
Some blankets are specifically designed to cool, such as those that contain Coolmax or 37.5 technology. Coolmax is moisture-wicking and breathable, while 37.5 fabric is designed to maintain an ideal body temperature.
If you sleep hot on your mattress but aren’t ready to replace it, a mattress topper could help temporarily. A mattress topper is a layer of bedding that changes a mattress’s feel. Mattress toppers come in different thicknesses and materials.
Mattress toppers that contain memory foam are most likely to retain heat. Unless they are aerated and infused with gel, charcoal, or some other cooling element, they aren’t the best choice for hot sleepers. Similarly, down mattress toppers also tend to retain heat.
Cooling mattress toppers include those made with naturally-breathable wool, and those that use cooling technologies such as phase change material.
Innerspring mattresses sleep the coolest, followed by latex and hybrid beds. The warmest mattresses tend to be made entirely of foam. There are many reasons for the differences in temperature regulation among mattress types, but the most important factor tends to be airflow.
Innerspring and hybrid beds allow for excellent airflow through their coils, but hybrid beds tend to sleep warmer due to their foam comfort systems. Foam does not permit airflow and often contours closely to the body for reduced airflow even on the surface, making these the warmest mattresses overall. Heat retention also plays a role, as latex has minimal airflow but naturally retains less heat than synthetic foam. However, mattresses are often designed to mitigate these factors.
While the average foam bed may be too warm for a hot sleeper, there are foam beds with unique features meant to prevent heat retention and encourage airflow. Mattress type is important when determining how warm a mattress will be, but it isn’t the only thing to consider.
If your mattress sleeps too warm, but you’re not in the market to buy a new one, you can cool down your bed by purchasing a cooling mattress pad or switching your bedding out for something more breathable. Cooling mattress toppers are available in a wide range of styles, from naturally breathable materials to innovative water-powered technology.
Prices also vary significantly depending on the topper’s design, but even a budget-friendly cooling pad can lead to much more comfortable nights. Bedding also plays a crucial part in how warm your bed is, so warm sleepers should ensure their sheets are made of a breathable material that wicks moisture away from the body.
