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.

The Best Cooling Mattresses for Hot Sleepers

Product Details

Helix Midnight

Helix Midnight
Mattress Type:
Hybrid
Firmness:
Medium Firm (6)
Helix Midnight
Highlights:

The Helix Midnight is a medium firm mattress constructed of close-conforming memory foam and a robust coil system that provides pressure relief, support, and temperature neutrality.

Who it's best for:
  • Sleepers who prefer the contouring and responsive feel of a memory foam hybrid
  • People who frequently experience pain and pressure points
  • Hot sleepers

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. The middle of the road option here is the Helix Midnight, which features a medium firm feel that suits most sleepers.

The Helix Midnight features a 4-layer hybrid construction. The comfort layers consist of a top layer of responsive polyfoam and a second layer of close-conforming memory foam. This combination provides a balance of conforming and responsiveness, allowing the mattress to relieve pressure while still retaining some ‘bounce’. Under the comfort layers is a transition layer of polyfoam.

The support core is made of pocketed coils. In addition to providing a supportive base, coils allow for a ton of airflow and don’t trap body heat like foam does. Consequently, the Helix Midnight sleeps cool.

The Helix Midnight is also available ina Luxe version, which adds, an enhances, zoned support core and a plush pillow top. Helix Sleep’s standard hybrids are priced much lower than the average hybrid model. The Luxe models cost a bit more, but still have reasonable sticker prices. Helix Sleep provides free shipping to all 50 states, as well. All mattresses come with the same 100-night sleep trial. Standard models are backed by 10-year warranties, and Luxe models are backed by 15-year warranties.

DreamCloud

DreamCloud
Mattress Type:
Hybrid
Firmness:
Medium Firm (6)
DreamCloud
Highlights:

The DreamCloud’s breathable hybrid design and gel-infused memory foam work to dissipate excess heat, keeping the bed sleeping cool all night long.

Who it's best for:
  • People who sleep hot
  • Couples
  • Sleepers of all sizes and sleeping positions

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.

Nolah Original

Nolah Original
Mattress Type:
Foam
Firmness:
Medium (5)
Nolah Original
Highlights:

Nolah’s Original mattress provides a comfortable blend of body-contouring and breathable overall support, allowing the bed to sleep coolly and comfortably without trapping too much heat.

Who it's best for:
  • Sleepers who prefer the close conforming of adaptive polyfoam
  • People who weigh 230 pounds or less
  • Couples

Many all-foam mattresses sleep hot because they do not circulate air very well. The surface layers absorb and trap body heat, which in turn can cause the entire mattress to feel uncomfortably warm. The Nolah Original 10 is a notable exception. The comfort layer is composed of adaptive polyfoam that is fairly breathable and shouldn’t retain too much body heat. The polyfoam doesn’t sink like memory foam, so you’ll also be able to enjoy steady surface airflow.

The Nolah Original 10 is considered a medium (5) feel model. The close contouring and ample cushioning makes this mattress ideal for side sleepers who weigh up to 230 pounds. These individuals typically need a plusher mattress to cushion their shoulders and hips, align the spine, and reduce pressure. The mattress also provides adequate support for back and stomach sleepers who weigh less than 130 pounds. We recommend the Nolah Original 10 to couples, as well. The foam layers isolate motion and prevent it from transferring across the surface, which can cut down on disturbances for co-sleepers, and the mattress does not make any noise.

The mattress is reasonably priced compared to other all-polyfoam models, and Nolah throws in standard ground shipping at no extra charge. If you’d like to cut the sticker price even further, Nolah allows you to opt out of the 120-night sleep trial. The mattress comes with a 15-year warranty.

Layla

Layla
Mattress Type:
Foam
Firmness:
Medium Soft (4), Firm (7-8)
Layla
Highlights:

Thermo-Gel technology and a copper infusion keep the flippable memory foam Layla mattress cool all night.

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

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.

Brooklyn Bedding Aurora

Brooklyn Bedding Aurora
Mattress Type:
Hybrid
Firmness:
Medium Soft (4), Medium Firm (6), Firm (7-8)
Brooklyn Bedding Aurora
Highlights:

The Brooklyn Bedding Aurora consists of a cooling phase-change cover, foam comfort layers infused with cooling gel, and a breathable pocketed coil support core.

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

The Brooklyn Bedding Aurora is a luxury hybrid packed with cooling features. Consisting of a cooling phase-change cover, foam comfort layers infused with cooling gel, and a breathable pocketed coil support core, the Aurora is one of the most temperature neutral hybrids on the market.

The Brooklyn Bedding Aurora 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 Aurora 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 Aurora 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 Aurora mattress is made in the US and comes with a 10-year warranty. Given its high-quality construction, the Aurora mattress is priced low compared to similar hybrid mattresses.

WinkBed

WinkBed
Mattress Type:
Innerspring
Firmness:
Soft (4), Medium (6), Firm (7), Plus (8)
WinkBed
Highlights:

The WinkBed comes in four firmness options and sleeps cool as a result of gel-infused foam and airflow through the coil layer.

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

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.

PlushBeds Cool Bliss

PlushBeds Cool Bliss
Mattress Type:
Foam
Firmness:
Medium Firm (6)
PlushBeds Cool Bliss
Highlights:

The PlushBeds Cool Bliss combines the pressure-relieving benefits of cooling gel memory foam with breathable, organic latex to keep sleepers supported and cool through the night.

Who it's best for:
  • People who sleep hot
  • Those who like the feel of memory foam
  • Side sleepers

The PlushBeds Cool Bliss is an all-foam bed made with a thick layer of proprietary Cool Bliss gel memory foam that is breathable and helps dissipate excess body heat. A layer of supportive, organic latex prevents the quicksand feeling traditionally associated with memory foam. This mix of materials combines the pressure-relieving contouring of memory foam with the supportive, full-body cradling of latex. The latex layer is naturally breathable and situated on top of a foam layer with a convoluted design to further boost air circulation through the bed.

The Cool Bliss mattress has a medium firm (6) feel, giving it a middle of the road firmness that’s suitable for a variety of different kinds of sleepers. The bed’s latex layer and core of high-density polyfoam provide strong support and resist overcompression.

The mattress is equipped with multiple cooling features to allow those who tend to sleep hot to enjoy the benefits of memory foam. The hug of memory foam is particularly nice for side sleepers, helping to take pressure off of the hips and shoulders. The thick layers of foam and latex provide a substantial amount of motion isolation with some underlying bounce and resilience.

The PlushBeds Cool Bliss ships for free to the contiguous U.S. The mattress is backed by a 100-night sleep trial as well as a 25-year warranty.

Eight Sleep Pod

Eight Sleep Pod
Mattress Type:
Foam
Firmness:
Medium (5)
Eight Sleep Pod
Highlights:

A dynamic cooling and heating system allows sleepers to program the Eight Sleep Pod mattress to the precise temperature they desire.

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

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.

Saatva

Saatva
Mattress Type:
Innerspring
Firmness:
Soft (2-3), Medium Firm (6), Firm (7-8)
Saatva
Highlights:

The Saatva Classic is a supportive hybrid mattress that’s constructed to allow for tons of airflow.

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’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 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.

GhostBed Luxe

GhostBed Luxe
Mattress Type:
Foam
Firmness:
Medium (5)
GhostBed Luxe
Highlights:

The GhostBed Luxe is an all-foam mattress constructed with phase-change material that’s designed to draw heat away from the sleeper.

Who it's best for:
  • Those who share a bed
  • People who sleep hot but like the feel of an all-foam bed
  • Individuals who weigh under 230 pounds

The Ghostbed Luxe is an all-foam mattress designed with several features that are intended to help hot sleepers stay cool. All-foam mattresses have a tendency to trap heat, but the thoughtful design of the GhostBed Luxe includes many materials to counteract heat build-up.

The cover is quilted with a phase-change material that draws heat away from the surface, as well as fiber that allows for airflow, and gel-infused memory foam. Beneath that is a 2-inch comfort layer of gel memory foam that’s laminated with phase-change material and a second 2-inch comfort layer of high-density polyfoam. This combination of comfort layers results in a plush, closely contouring feel that ranks at a medium firmness.

The mattress’ medium firmness suits most sleepers under 230 pounds, and is particularly well-suited to lightweight individuals and side sleepers, as the bed’s plush comfort layers form a deep cradle that offers good pressure relief.

The GhostBed Luxe is made in the US and ships free to the lower 48 states. The bed is backed by a 101-night sleep trial with a 30-day break in period and a 25-year warranty.

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.
