Human body temperatures naturally rise and lower over the course of a day, and different temperatures correspond with how tired we feel, how easily we fall asleep, and how soundly we stay asleep. Studies show that lower body temperatures overnight tend to promote better sleep, while higher body temperatures can interrupt the sleep cycle.

For these reasons, it’s important that people who tend to sleep hot opt for cooling mattresses. A cooling mattress can make the difference between a good night’s sleep and a night full of sweaty tossing and turning. Cooling mattresses are available at reasonable prices, too, so hot sleepers don’t need to worry about breaking the bank.

Keep reading to learn which mattresses are the best for hot sleepers. A variety of cooling mattresses exist, so you’ll want to pay attention to other mattress details to ensure you choose the best mattress for you. In this guide, we’ve outlined which mattresses are best for hot sleepers of different weights and sleep position preferences.

Product Details

Brooklyn Bedding Signature

Who it's best for:
  • Sleepers of any body weight or preferred sleep position
  • People who tend to sleep hot
  • Couples that share a bed
Brooklyn Bedding Signature

Airflow through the coil layer of the Brooklyn Bedding Signature mattress helps keep sleepers cool throughout the night. The pocketed coil layer makes up 6 inches of the mattress’s 11.5-inch thickness. Additionally, Brooklyn infuses TitaniumGel, a proprietary gel formula, into the top two comfort layers to help keep sleepers temperature neutral.

The Brooklyn Bedding Signature mattress comes in three firmness levels: Soft, Medium, and Firm. With so many options, this mattress works for sleepers of all body weights. This mattress also performs well with sleepers regardless of if they sleep on their backs, stomachs, sides, or in a combination of positions.

The Signature mattress conforms to the body, and has the classic memory foam feel of sleeping “in” the mattress. Most sleepers find immense pressure relief from this mattress. Like many conforming foam mattresses, the Signature isolates motion well. Couples who share a bed aren’t likely to be disturbed by one another’s movement during the night, since the mattress doesn’t transfer much motion.

Brooklyn Bedding makes their mattresses on demand, then ships them compressed in boxes. Customers are given a 120-night sleep trial during which they can return or exchange the mattress at no charge if it doesn’t fit their needs. The Signature mattress is made in the US and comes with a 10-year warranty. Given its high-quality construction, the Signature mattress is priced low compared to similar hybrid mattresses.

Saatva

Who it's best for:
  • Sleepers of all body weights and sleep position preferences
  • People who tend to sleep hot
  • Shoppers on a budget
Saatva

Saatva’s flagship mattress, the Saatva Classic, keeps hot sleepers cool because of airflow through its coil layers. The Saatva Classic 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 120-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.

Eight Sleep Pod

Who it's best for:
  • People who sleep hot
  • Couples that share a bed
  • Customers interested in smart products
Eight Sleep Pod

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. 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.

Layla

Who it's best for:
  • Sleepers wanting two firmness options in one mattress
  • People who sleep hot
  • Average and light-weight sleepers
Layla

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 Laya.

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.

WinkBed

Who it's best for:
  • Sleepers of all body weights
  • People who experience back pain
  • Sleepers who prefer a responsive mattress
WinkBed

The WinkBed is a hybrid mattress that comes in soft, medium, firm, and plus firmness levels. 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.

Purple

Who it's best for:
  • People who sleep hot
  • Couples
  • Shoppers on a budget
Purple

The Purple mattress is constructed with a unique comfort layer called the Purple Grid. The Purple Grid is a grid-shaped polymer layer that allows air to flow throughout the top of the mattress. The Purple Grid also gives sleepers a floating feeling, so the Purple mattress is a good choice for those who like to feel like they’re sleeping “on” rather than sinking “in” to a mattress.

The Purple mattress only comes in one firmness layer, which is medium-firm. As a result, not all sleepers will be able to make the Purple mattress work for them. Light and average-weight sleepers tend to prefer the Purple, while some heavyweight sleepers don’t feel like it provides enough support.

Motion isolation and noise are two areas in which the Purple mattress excels, making it a good choice for couples. Most people will not be disturbed by motion transferring across the mattress as their partner moves during the night. Also, the Purple is virtually silent due to its all-foam construction. One area in which the Purple lags is edge support. This mattress does tend to buckle when weight is put on the edges of the bed.

Purple mattresses are made in the US and ship for free to the contiguous US. They come with a 100-night sleep trial and a 10-year warranty. Customers wanting to return a Purple mattress during the sleep trial must wait until they’ve tried it out for at least 30 nights.

Bear Hybrid

Who it's best for:
  • People who sleep hot
  • Light and average-weight sleepers
  • Couples
Bear Hybrid

The Bear Hybrid stays temperature neutral due to its coil layer and cover material. Eight inches of pocketed coils allows for airflow through the mattress all night. The cover is made with Celliant fibers, which absorb body heat. In addition to keeping sleepers cool, Celliant fibers are thought to transform body heat into infrared energy, which is then transmitted back to the sleeper to aid in physical recovery.

Medium-firm is the only firmness level the Bear Hybrid mattress is available in. As a result, this mattress tends to work better for light and average-weight sleepers. Sleepers who weigh over 230 lbs. might find that the Bear Hybrid doesn’t provide them enough support.

The Bear Hybrid is a quiet mattress, but it doesn’t isolate motion as well as some all-foam mattresses. The motion transfer won’t bother most sleepers, but very sensitive sleepers who share a bed might be aware that they can feel motion when their partner moves. This mattress has above-average durability, so it should last for several years.

Customers can order the Bear Hybrid online. The mattress ships to all 50 US states for free and comes with a 100-night sleep trial and 20-year partially prorated warranty. Customers may opt for white glove delivery and old mattress removal, but both come with a fee. Anyone wanting to return or exchange their Bear Hybrid under the sleep trial must wait until after a 30-night break-in period.

How to Find a Cooling Mattress

Choosing a mattress is a difficult decision because there are many variables you must consider, especially when looking for a cooling mattress. Cooling mattresses come in many different varieties, so it’s important for customers to be aware of key mattress characteristics and how they affect the performance of a mattress.

Keep reading to learn about mattress pricing, how your preferred sleep position affects which mattress will work for you, mattress types, materials used to construct mattresses, and more.

What is a Cooling 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.

What to Look for in a Mattress

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.

  • Price: Cooling mattresses can be found across the price spectrum. Mattress price is usually a result of the materials used to construct the mattress. Higher-quality and longer-lasting materials cost more, though there are affordable high-quality mattresses available. Direct-to-consumer mattresses sold online are often less expensive, since the manufacturer isn’t paying for showrooms and additional staff.
  • Sleeping Position: Your preferred sleep position will influence which mattress type and firmness level is best for you. For example, side sleepers often prefer softer mattresses that cushion their hips and shoulders. Back sleepers often prefer firmer mattresses that provide enough lumbar support. Of course, body weight greatly influences how soft or firm a mattress will feel to you.
  • Mattress Type: There are many mattress types available, including all-foam, innerspring, hybrid (a combination of coils and other materials), airbed, and latex. Innerspring and hybrid mattresses tend to be more temperature neutral due to airflow through their coil layers. Memory foam comfort layers, whether in all-foam or hybrid beds, tend to trap body heat.
  • Contouring: Contouring, also called conforming, refers to how much a mattress “hugs” the body. Memory foam is highly contouring and tends to trap heat. Many cooling mattresses are not highly contouring. For example, innersprings tend to be more temperature neutral and give a responsive feel.
  • Quality Materials: For each type of mattress material, there are varying levels of quality available. The higher density a polyfoam is, the higher quality the foam tends to be. Higher quality polyfoam will be more durable and not as prone to developing body impressions. Natural latex tends to be higher quality than synthetic latex.
  • Firmness Level: The mattress firmness scale ranges from 1 to 10, with 1 being the softest possible mattress and 10 being the firmest possible mattress. Firmness level is generally unrelated to a mattress’s cooling ability. Most people prefer mattresses in the 4.5 to 6.5 firmness range, though heavier-weight individuals often prefer even firmer mattresses.
  • Pressure Relief: When a mattress provides good pressure relief, the sleeper’s weight is evenly distributed across the surface of the mattress. With poor pressure relief, the sleeper has points of greater pressure, which can cause discomfort or pain. If a mattress is too firm or if it sinks in too easily, sleepers will develop pressure points.
  • Edge Support: Edge support refers to the firmness of a mattress’s edges when a person sits or lies near the edge of the bed. Strong edge support allows sleepers to use the full surface of a mattress without feeling at risk of rolling off. Strong edge support also makes getting in and out of bed easier.
  • Temperature Regulation: Cooling mattresses excel at regulating temperature so sleepers don’t overheat during the night. All mattress layers can contribute to temperature regulation. Coil layers allow cooling airflow through the mattress. Special cover fabrics and foam comfort layer infusions can also help regulate temperature by absorbing body heat.
  • Noise: Some mattresses make noise when people get on them or move around during the night. All-foam mattresses tend to be the most quiet, and can be virtually silent. Hybrid and innerspring mattresses tend to produce more sound due to their coil layers. Individually-encased pocketed coils are quieter than innersprings, however.

The Cooling Ability of Different Types of Mattresses

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.

Hybrid

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.

Foam

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.

Innerspring

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.

Latex

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.

Airbed

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.

Cooling Mattress Materials

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.

  • Coils & Springs: Coils and springs are most commonly made of steel and used in a mattress’s support core. Because their layers contain so much open space, they allow for air to flow through the mattress, which cools the comfort layers above.
  • Latex: Made from rubber tree sap, natural latex layers are generally cooler than polyfoam, but can trap heat. Talalay latex is known for retaining less heat than Dunlop latex. Synthetic latex tends to trap heat more than natural latex. All latex types can be aerated for breathability.
  • Gel-infused foam: Some manufacturers infuse memory foam comfort layers with gel in an effort to promote cooling, but how well it works is debatable. Sleepers who tend to sleep hot might want to focus more on the mattress type than whether or memory foam layers contain gel.
  • Basic memory foam: Basic memory foam is made of polyurethane. It conforms to the body in response to heat, providing a “hugging” sensation. Basic memory foam also tends to retain heat, so people who sleep hot might have trouble sleeping comfortably on it.
  • Advanced memory foam: Scientists have worked to make basic memory foam more breathable and less heat-retaining. Advanced memory foam is the result of their efforts and often contains a pattern of small holes that allow airflow or gel-infused beads meant to promote cooling.
  • Basic polyfoam: Like memory foam, polyfoam is made from polyurethane, commonly used in mattresses, and can trap heat. Basic polyfoam can be used both in a support core or as a comfort layer. It differs from memory foam in that it’s much less conforming.
  • Advanced polyfoam: Advanced polyfoam, sometimes called open cell polyfoam, is an improvement upon basic polyfoam. This newer form of polyfoam contains small cells or air bubbles that increase the foam’s breathability and reduce heat retention. Mattresses with advanced polyfoam are more temperature neutral.

The Ideal Sleeping Environment for Hot Sleepers

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.

What is the Best Temperature for Sleep?

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.

Sheets

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.

Pillows

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.

Blankets

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.

Mattress Toppers

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.
