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.

The Best Cooling Mattresses for Hot Sleepers

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.

What It’s Made of

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 as well as support. The support core is made of pocketed coils, followed by a base layer of high-density foam.

How It Performed

The support from the transitional layer prevents your body from sinking too deep into the bed. Between this and the conforming memory foam layers, the mattress relieves pressure while still retaining some bounce, making it a good match for 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 sleeps quite cool.

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.

Lab Notes – What Our Testers Thought

“During our tests, we found that the Midnight Luxe sleeps exceptionally cool for a pillow-top hybrid. The cover is breathable, the coils generate enough circulation to keep the foam from trapping too much heat, and the firmer feel means most people won’t sink too much and lose their surface airflow.”

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. These attractive features result in a bed that a wide variety of sleepers should find quite comfortable.

What It’s Made of

The DreamCloud combines layers of high-quality foam with a robust base of coils to provide a balanced sleeping experience. The cover is composed of a cozy cashmere blend that feels soft to the touch. This is quilted with polyfoam to create an instantly cushioned surface. Beneath is a layer of gel-infused memory foam that conforms closely and generates a deep body hug, followed by a polyfoam layer that promotes further contouring but has a firmer feel to prevent excessive sinkage. Next is a breathable bed of coils that 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.

How It Performed

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 bed’s support core of individually wrapped coils allows 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 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.

Lab Notes – What Our Testers Thought

“We didn’t notice much heat absorption while testing the DreamCloud. This is unusual for a pillow-top mattress with memory foam, but the cashmere-blend cover really helps keep the surface cool.”

Saatva Classic

Buy more, save more. Get up to $450 off.

Since uneven support and excessive sinkage can exacerbate pain from poor sleep posture, many heavier sleepers require a mattress that will reinforce their bodies and keep them on an even plane. The Saatva Classic has a luxury design that delivers outstanding stability without sacrificing comfort or pressure relief.

What It’s Made of

The Classic begins with a Euro-top padded with foam and soft fibers, followed by a zoned memory foam layer. The transitional layer consists of pocketed minicoils, while the support core contains thick bonnell coils made from recycled steel. The dual coil layers provide excellent pushback along the edges and make it easier to get in and out of bed. Both coil layers also promote excellent airflow to keep you cool and comfortable throughout the night.

How It Performed

Three firmness levels are available, allowing you to choose the most suitable feel based on factors like body type and sleep position. The medium firm (6) option offers decent support as well as some light contouring, while the firm (8) feel is the most robust option for heavier sleepers, whether they sleep on their side, back, or stomach. If you aren’t satisfied with your initial choice, Saatva allows exchanges for a small transportation fee. You can also choose between a mattress height of 11.5 or 14.5 inches, depending on your profile preferences.

All Saatva customers in the contiguous U.S. qualify for free White Glove delivery, which includes full assembly anywhere 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.

Lab Notes – What Our Testers Thought

“We liked the Saatva Classic’s ultra-responsive feel, owing to its coil-on-coil construction. Our testing showed people who weigh more than 230 pounds are most likely to prefer the medium firm or firm feel on the 14-inch profile.”

WinkBed

Get $300 off all mattresses

Finding the right cooling mattress can be challenging for side sleepers. Many 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.

What It’s Made of

The WinkBed is available in four firmness levels: medium soft (4), medium firm (6), and firm (7), plus a WinkBed Plus option with a firm (8) feel. All mattresses begin with a layer of polyfoam quilted into the cover, followed by an additional polyfoam layer. The quilted polyfoam conforms to the body, 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 helps prevent deep sinkage when you get in and out of bed. The entire mattress is encased in a breathable, eucalyptus-derived Tencel fabric cover.

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 mold closely to the body while the coils create a strong support system to prevent you 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 absorb movement well, and the coils don’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.

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

Lab Notes – What Our Testers Thought

“Thanks to its breathable construction, the WinkBed contours closely without bottling up heat. All the side sleepers on our team felt comfortable on this bed.”

  • 365-night sleep trial
Nectar Premier Copper

$599 off! $100 off + $499 in free accessories included.

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 an especially good choice for side sleepers who prioritize plush, comfortable sleeping surfaces with deep pressure relief.

What It’s Made of

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. Beneath is a 4-inch layer of memory foam infused with cooling gel and phase change material, both of which are intended to help maintain temperature neutrality on the bed’s surface. Next is a thin layer of firmer transitional polyfoam, followed by a 9-inch base layer of high-density polyfoam that stabilizes the mattress.

How It Performed

The memory foam layer conforms closely to the body, resulting in excellent pressure relief for sleepers who experience painful pressure buildup at night. The foam also excels in motion isolation, which may appeal to those who need a bed that reduces sleep disturbances from a partner’s movement. 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.

Lab Notes – What Our Testers Thought

“Many memory foam mattresses sleep hot because they cradle the body too closely. I didn’t sink much on the Premier Copper, plus there wasn’t a lot of heat retention in the comfort layer – the phase change infusion is pretty effective.”

A mattress’ comfort level is a matter of subjectivity, but some beds are designed to feel comfortable for a wide swath of sleepers. The Brooklyn Bedding Aurora Hybrid is one such mattress. It comes in three firmness levels to accommodate most types of sleepers.

What It’s Made of

The Aurora Hybrid is available in medium soft (4), medium firm (6), and firm (7) feels. All options feature a top layer of CopperFlex foam that conforms to the body but is also slightly responsive. Next is a layer of TitanFlex foam that is firmer in feel. 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.

How It Performed

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

Hot sleepers will appreciate the cooling features in the Aurora Hybrid. The cover fabric and CopperFlex foam are both confused with TitanCool, a phase change material that is meant to wick moisture from the body and maintain a neutral temperature. The coils also enable air to circulate and keep the bed cool.

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 10-year warranty.

Lab Notes – What Our Testers Thought

“Nearly all of our testers found a firmness option that felt comfortable to them. Testers who enjoy sinking into the bed particularly liked the soft option, while stomach sleepers enjoyed the feel of the firm.”

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.

What It’s Made of

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. These two comfort layers offer above-average cushioning for a hybrid bed. 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.

How It Performed

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.

Lab Notes – What Our Testers Thought

“I felt very little heat retention from the Evolution 15’s comfort layer compared to the memory foam in other hybrids we’ve evaluated. Most of us agreed the medium firm and firm models provided the best cooling.”

Bear Hybrid

30% off sitewide, plus 2 free Cloud Pillows with mattress purchase

For those seeking a bed that can relieve aches and pains, the Bear Hybrid is designed to promote physical recovery at night. The mattress has a foam and coil design that helps reduce pressure points, with a Celliant textile cover engineered to provide restful sleep.

What It’s Made of

The cooling cover draws heat away from the body and is quilted with gel-infused polyfoam. A second layer of polyfoam offers additional contouring and helps keep your spine aligned. Beneath is a transition layer of polyfoam that circulates air throughout the comfort system and helps enhance pressure relief. The support core contains pocketed coils that are reinforced along the perimeter. A thin layer of high-density polyfoam adds durability for the entire bed.

How It Performed

The Bear Hybrid is medium firm (6) and easy to move around on for most people. Contouring from the thick polyfoam comfort system provides relief for sleepers who experience painful pressure buildup at night. At the same time, the polyfoam is somewhat responsive and the coils add bounce to the mattress. This even balance of support and cushioning makes the bed especially well suited to side sleepers between 130 and 230 pounds and back sleepers under 130 pounds.

The Celliant cover is engineered to regulate temperature while the coil base increases the amount of airflow throughout the mattress, so hot sleepers should sleep fairly comfortably. Reinforced edge coils ensure strong edge support for couples and those who sleep near the perimeter of the bed.

The Bear Hybrid comes with a 120-night sleep trial and is covered by a lifetime warranty. Bear ships free to the contiguous U.S.

Lab Notes – What Our Testers Thought

“I usually find foam surfaces too plush, but the polyfoam layers on the Bear Hybrid are surprisingly supportive while keeping that quintessential foam feel.”

GhostBed Venus Williams Legend

30% off all GhostBed mattresses & 2 free pillows. Free weighted blanket ($479 Value) with a minimum $1.5k order.

The GhostBed Venus Williams Legend is an all-foam mattress engineered to optimize physical recovery in athletes and people with active lifestyles. The balanced design and medium firm (6) feel help keep your head, neck, and spine properly aligned during sleep.

What It’s Made of

The bed begins with a cover made of cooling fibers and REPREVE, a soft material derived from recycled sources. Beneath is a comfort layer made of memory foam that closely contours to the body to help relieve pressure buildup. The foam is infused with a mineral engineered to absorb body heat and reflect it back as far-infrared light. This light warms and soothes tired muscles without heating up the bed. Underneath the memory foam is a layer of Ghost Bounce foam that balances contouring with latex-like responsiveness, keeping you from sinking too deep. The bed’s base is composed of high-density foam for sturdiness and support.

How It Performed

The GhostBed Venus Williams Legend is a superior choice for sleepers who experience painful pressure points during sleep. The well-cushioned surface cradles the body and prevents pressure from accumulating in areas like the shoulders, hips, and spine. The cushioning also helps absorb motion, which may be appealing to co-sleepers who tend to wake each other up with movement at night. The balance of plushness and support is excellent for side sleepers across all weight categories. The surface cradles a side sleeper’s shoulders and hips, but the bed is still supportive enough to prevent the lower back from sagging excessively. Back sleepers up to 230 pounds should find the bed comfortable, as well.

GhostBed allows customers to try out the bed for 101 nights. After an initial 30-night break-in period, you may return the mattress during the trial for a full refund with free return shipping. The mattress is also backed by a 25-year warranty. Shipping is free to the contiguous U.S.

Lab Notes – What Our Testers Thought

“As a side sleeper, I really enjoyed the GhostBed Venus Williams Legend’s cushioning. It cradled my shoulders and hips, but I also never felt like I was sagging into the bed.”

Birch Mattress

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.

What It’s Made of

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.

How It Performed

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. This model is a great choice if you prioritize ease of movement across the bed. The buoyant surface may appeal to sleepers who prefer the feeling of sleeping “on” the bed rather than “in” it.

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.

Lab Notes – What Our Testers Thought

“An organic cotton cover, a latex comfort layer that doesn’t trap too much heat, coils that generate solid airflow – the Birch has a lot of cooling elements working in its favor. As someone who frequently feels sweaty in bed, I thought the wool batting layer was an especially nice touch.”

The Eight Sleep Pod is an all-foam smart mattress that allows sleepers to program the bed to certain temperatures at set times. It’s a worthwhile option for co-sleepers who have different temperature preferences at night.

What It’s Made of

The Eight Sleep Pod is 11 inches thick and is constructed with three layers of foam. The top two layers of polyfoam conform to the body, while a support core of high-density polyfoam provides a sturdy base. A layer sandwiched between the foam layers contains a grid of tubes. A pump that must sit next to the bed pushes water of adjustable temperature through the grid, either cooling or heating the mattress.

How It Performed

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, medium firm (6), the mattress won’t work for everyone. Sleepers weighing up to 230 pounds are most likely to find a pleasant mix of support and cushion in this bed. The mattress runs on the higher end of the price scale because of its high-tech features. A smartphone app is included with the price, offering scheduled temperature readings and daily sleep reports.

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.

Lab Notes – What Our Testers Thought

“The Pod works as advertised. The temperature adjustments are easy to configure, and there’s a noticeable difference between the cooling and heating settings. Simply put, this mattress is unparalleled with regard to temperature regulation.”

Why You Should Trust Us

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.

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. These “mattress in a box” models are comparable to those sold in brick-and-mortar stores in terms of construction and performance.
  • 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’ 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 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 core 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. Latex comfort layers can further enhance cooling, but thick memory foam comfort layers could cause a hybrid mattress to trap heat.

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’ 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: Latex has natural cooling properties. Many manufacturers also aerate their latex mattress layers, or perforate 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’ 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 beds more cooling and breathable, while others trap heat. People who sleep hot need to understand which components are most cooling, so they know what to look for when mattress shopping.

Key Cooling Materials
  • Coils & springs: Coils and springs are most commonly made of steel and used in a mattress’ 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, the best pillow may be 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’ 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.

Frequently Asked Questions

  • What mattress types sleep cool at night?

    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.

  • How can you cool down a mattress?

    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.

  • Do cooling mattresses really work?

    Many mattresses are constructed with materials intended to promote airflow and retain a low amount of body heat. That said, some cooling mattresses offer better breathability and temperature control than others.

    Our testing has found that, among the different mattress types, latex hybrids usually sleep the coolest. The latex in these mattresses is often ventilated to circulate air near the surface and prevent overheating. The coil systems that make up the support cores in these mattresses also generate a fair amount of airflow. Additionally, latex hybrids often feature covers made of naturally breathable materials like organic cotton or wool.

    All-latex beds also tend to sleep cool. Although the solid latex in their support cores don’t offer the same level of airflow as coils, many of these mattresses consist of ventilated layers and breathable cover materials. Airbeds, which have adjustable air chambers in their support cores, also provide above-average temperature neutrality – though these mattresses tend to be quite expensive.

    While foam mattresses typically sleep hotter than other mattress types, some brands integrate cooling components into their beds to reduce heat retention. Comfort layers are often infused with gel, graphite, copper, and other materials designed to draw heat away from the surface and maintain a comfortable temperature for sleeping.

    Sleep trials can make a world of difference. Be sure to test out any mattress you’re interested in buying for the entire trial period. If you notice uncomfortable overheating, then that model may not be right for you.

  • What can I do if my bed is too hot?

    If you tend to overheat in bed, there are a few measures you can take to sleep at a more comfortable temperature. Choosing the right sleep accessories is a good starting point. Cooling sheets made from breathable materials such as cotton percale, linen, or rayon derived from bamboo can help offset heat retention from a mattress that sleeps too warm. A cooling mattress pad that uses passive or active temperature control may also be helpful.

    You can optimize your bedroom environment by adjusting the thermostat. Most doctors recommend an ambient temperature of 60 to 67 degrees for sleeping. During the summer months, you can also use a fan, air conditioner, or swamp cooler to keep your bedroom at a comfortable temperature.

    If these measures don’t work, then you should consider buying a new mattress that provides better temperature control than your current model. To ensure your replacement mattress provides sufficient cooling, we recommend taking full advantage of in-home sleep trials. Most online mattress brands offer trial periods that span at least 90 nights in length and some last up to a year. One advantage of longer trials is that you’ll be able to test out the mattress during different seasons.
