Human body temperatures naturally increase and decrease over the course of a single day, and studies have shown your temperature changes during different stages of your sleep cycle. A 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 of sweaty tossing and turning. The materials used in mattresses can play a role in how well – or poorly – a mattress regulates temperature. To choose our top picks, we evaluated each mattress for breathability and temperature control, but also took additional factors into account such as quality of construction and expected lifespan.
Watch our video below to learn more about our lab’s top picks for cooling mattress.
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. While you’re shopping for cooling mattresses, you can also check out our guides to cooling sheets, pillows, and mattress pads.

If you’re in the market for a new mattress but aren’t sure about your ideal firmness level, Helix Sleep offers a wide selection of memory foam hybrid models designed for specific body types and sleep positions. We found the Midnight Luxe to be one of the brand’s most well-rounded models, and it’s designed 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 Midnight Luxe, which our testers rated medium firm (6). The Midnight Luxe contains two layers of memory foam beneath the pillow-top to give the surface a plush feel. A polyfoam transitional layer provides extra conforming as well as support. The support core is made of pocketed coils, followed by a base layer of high-density foam.
How It Performed
During testing, the support from the transitional layer prevented testers’ bodies from sinking too deep into the bed. Between this and the conforming memory foam layers, the mattress relieved pressure while still retaining some bounce, making it a good match for our team’s side sleepers who experience pressure buildup in the shoulders and hips. The pocketed coils provided a supportive base and also allowed for steady airflow, reducing heat retention that may be associated with foam layers. Consequently, the Helix Midnight Luxe slept 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.
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 our test team rates highly for a wide variety of sleepers.
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 felt soft to the touch for our testers. This is quilted with polyfoam to create a cushioned surface. Beneath is a layer of gel-infused memory foam that conformed closely and generated a deep body hug during testing, followed by a polyfoam layer that promoted 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 felt like a combination of sleeping “in” and “on” the mattress.
How It Performed
The bed’s coil core and medium firm (6) feel gave it a versatile blend of cushioning and strong support during our in-house tests, making it comfortable for most of our testers. We think 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 allowed 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.
You won’t notice much heat absorption with the DreamCloud, which is unusual for a pillow-top mattress with memory foam. The cashmere-blend cover helps keep the surface cool.

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 delivered outstanding stability without sacrificing comfort or pressure relief during our testing.
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. We found the dual coil layers provided excellent pushback along the edges and made it easier to get in and out of bed. Both coil layers also promoted excellent airflow to keep our testers cool and comfortable.
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 soft (3) model was an excellent fit for side sleepers on our team, especially those who experience painful pressure points in the shoulders at night. The medium firm (6) option offered strong support to our testers as well as some light contouring. The firm (8) felt like the most robust option for our testers over 230 pounds, regardless of 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.
The Saatva Classic offers an ultra-responsive feel, owing to its coil-on-coil construction. With two profiles and three firmness options, this is one of the most versatile hybrids on the market.
Best for Side Sleepers
Get $300 off all mattresses
Picking the right cooling mattress can be challenging for side sleepers. We’ve found that people who primarily use this position experience pressure buildup along the spine, so they need an adaptive mattress that promotes even alignment and cushions the shoulders and hips. Thanks to a combination of foam layers and breathable components, we think the WinkBed is a good compromise for side sleepers seeking a cool, comfortable, and supportive mattress.
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 in the medium soft, medium firm, and firm models. The Plus has a latex layer instead of polyfoam. We noticed gentle conforming from the quilted polyfoam, resulting in even weight distribution and reduced pressure buildup. The transitional polyfoam layer provides moderate cushioning while serving as a buffer between your body and the support core. The medium soft model includes an extra layer of polyfoam for added cushioning.
As a hybrid model, the WinkBed uses pocketed coils for stability. These coils are designed to move independently from one another, creating a sturdy support system without generating too much bounce or motion transfer. Extra reinforcement along the perimeter helped prevent deep sinkage when our testers got in and out of bed. 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 molded closely to the body while the coils created a strong support system to prevent testers from sinking too deeply. Thanks to the range of firmness options, sleepers in most weight categories on our testing team found a model that felt comfortable.
Motion isolation is another area where the WinkBed performed well compared to other hybrid models. The top layers absorbed movement well, and the coils didn’t produce much responsiveness. At the same time, the edges felt secure thanks to the zoned coil system, and none of us sank excessively when moving across the surface. Steady airflow through the coils and the moisture-wicking Tencel cover also earned the WinkBed positive marks during our temperature control tests.
WinkBeds offers free ground shipping throughout the contiguous U.S. and a 120-night trial period. All WinkBed mattresses are backed by lifetime warranties.
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.

Nectar offers an array of memory foam beds, but the Premier Copper stood out to our testers for its higher profile and enhanced cooling properties compared to other all-foam models we’ve had in the lab. 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 that our testers rated medium firm (6). 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 conformed closely to the body when our testers lay on the bed, resulting in excellent pressure relief for testers who tend to experience painful pressure buildup at night. The foam also scored highly in our motion isolation tests, making this an attractive option for anyone who needs a bed that reduces sleep disturbances from a partner’s movement. Meanwhile the denser polyfoam layers provided adequate reinforcement, especially compared to other all-foam beds we’ve tested. The balance of contouring and support appealed to the side sleepers on our team, since they 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 lifetime warranty.
Many memory foam mattresses sleep hot because they cradle the body too closely, but we noticed less sinkage and heat retention on the Nectar Premier Copper.

A mattress’ comfort level is a matter of subjectivity, but some beds are designed to feel comfortable for a wide swath of sleepers. We found the Brooklyn Bedding Aurora Luxe is one such mattress. It comes in three firmness levels to accommodate most types of sleepers.
What It’s Made of
The Aurora Luxe is available in medium soft (4), medium firm (6), and firm (7) feels. All options feature a top layer of CopperFlex foam. We noticed this foam conformed to the body but was also slightly responsive. Next is a layer of TitanFlex foam that feels firmer. The medium soft and medium firm versions include a transitional layer of gel-infused memory foam beneath these two layers, while the firm model uses TitanFlex foam for enhanced support. All firmness options include a support core of pocketed coils that are zoned for extra support to the midsection.
How It Performed
The bed is designed with comfort in mind – just soft enough to cushion pressure points when we lay on it, but supportive enough to prevent sagging. All three firmness options excelled at relieving pressure buildup during our testing, which is especially important for side and back sleepers. Sleepers under 130 pounds found the medium soft option most comfortable, while sleepers who weigh over 230 pounds found the best support from the firm bed. The medium firm option is appropriate for many weight categories, depending on your sleep position.
The hot sleepers on our team appreciated the cooling features in the Aurora Luxe. 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.
The multiple firmness options means that most sleepers will find a model that feels comfortable. 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 excelled in our pressure relief tests, making it ideal for side sleepers and other people who experience pressure buildup 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. When our testers lay on the bed, they found these two comfort layers offered 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 earned positive reviews from testers who normally run hot during sleep. The foam layers are engineered to draw heat away from the body, and the coil system enables air to circulate. The bed is available in three firmness options, making it suitable for various sleep positions and sleep preferences. The side and back sleepers on our team preferred the plush and luxury firm options, which translate to medium (5) and medium firm (6) feels respectively. Stomach sleepers appreciated the 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.
You’ll feel very little heat retention from the Evolution 15’s comfort layer compared to the memory foam in other hybrids we’ve evaluated. Our testers agreed that the medium firm and firm models provided the best cooling.
Best for Back Pain
30% off sitewide, plus 2 free Cloud Pillows with mattress purchase
Most mattresses that alleviate back pain contour closely to the body, and this can lead to an uncomfortable sleep temperature if the cushioning layers absorb excess heat. With the Bear Elite Hybrid, you get the best of both worlds. Thick foam layers conform closely to promote even alignment and reduce soreness along your spine, but we found that the specialized cooling cover minimizes heat retention while you sleep.
What It’s Made of
A memory foam comfort layer and polyfoam transitional layer make up the Elite Hybrid’s comfort system. The memory foam is infused with copper, which has natural cooling properties. The polyfoam is divided into five different firmness zones. We noticed that this zoned design enhances support around the midsection – where people tend to carry extra weight – while offering gentler cradling for the head, shoulders, and legs.
The Elite Hybrid’s support core consists of pocketed coils over a high-density polyfoam base layer. Extra-strength coils along the perimeter provided pushback and decreased sinkage when our testers lay near the edges of the mattress or got in and out of bed. A cover made of Celliant-blend fabric encases the mattress. Celliant is engineered to dissipate heat on contact, resulting in a sleep surface that feels cool at all times – even on exceptionally hot or humid nights.
How It Performed
Elite Hybrid buyers choose from three firmness levels. During our tests, the Luxury Plush – a medium (5) model – earned the most favorable ratings from side and back sleepers weighing less than 130 pounds. This design offers the closest contouring and may sink a bit too much for sleepers who weigh more. The Luxury Firm (6) model was most popular among our side sleepers weighing 130 to 230 pounds, and back sleepers weighing up to 230 pounds. The most balanced of the three, this model cushions and supports the body in equal measure. Lastly, the Firm (8) model provided excellent reinforcement for side sleepers weighing more than 230 pounds, and back and stomach sleepers weighing at least 130 pounds.
Temperature control is a defining trait of this mattress. This can be attributed to the Celliant-blend cover, which actively releases heat from the surface, as well as steady air circulation through the coil system and the breathable, copper-infused memory foam comfort layer. Other strengths for the Elite Hybrid vary by firmness level. The two softest models performed well during our motion isolation and pressure relief tests, while the two firmest options feel more secure along the perimeter and don’t sink excessively when you move across the surface.
Bear offers free ground shipping throughout the contiguous U.S. Customers can opt for two free pillows with their purchase, or choose a discounted sleep accessories bundle featuring two pillows, a sheet set, and a mattress protector. All mattress orders are backed by 120-night sleep trials and lifetime warranties.
The Bear Elite Hybrid’s cool-to-the-touch cover should be suitable for people who need exceptional temperature control. Even on the softest version of the mattress, we felt very little heat retention from the foam layers.
Best for Athletes

The GhostBed Venus Williams Legend Hybrid is engineered to optimize physical recovery in athletes and people with active lifestyles. The balanced design and medium firm (6) feel helped keep our heads, necks, and spines properly aligned during testing.
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 and relieves pressure buildup when you lie on the bed. The foam is infused with a mineral engineered to absorb body heat and reflect it back as far-infrared light. This light is intended to warm and soothe your tired muscles without heating up the bed.
Underneath the memory foam is a layer of transitional foam that balances contouring with latex-like responsiveness, keeping you from sinking too deeply. The bed’s base is composed of pocketed coils over high-density base foam for sturdiness and support.
How It Performed
The GhostBed Venus Williams Legend Hybrid was a superior bed for sleepers on our team 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, earning the bed high marks in our motion isolation test. This may appeal to co-sleepers who tend to wake each other up with movement at night.
The balance of plushness and support was excellent for the side sleepers on our team across all weight categories. The surface cradled side sleepers’ shoulders and hips, but the mattress was still supportive enough to prevent the lower back from sagging excessively. Our back sleepers up to 230 pounds found the bed comfortable, as well.
GhostBed allows customers to try out the mattress 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.
Athletic sleepers of all body types should enjoy the GhostBed Venus Williams Legend Hybrid’s cushioning. It closely cradles the shoulders and hips, but you’ll never feel like you’re sinking too much into the bed.
Best Pressure Relief
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 offered excellent support for our testers as well as responsiveness for sleepers who preferred an even balance between the two.
What It’s Made of
The mattress is constructed with Talalay latex that cushioned pressure points during testing but also delivered enough pushback to lend support and prevent excessive sinkage. A core of pocketed steel coils provides a supportive, durable base. The bed is topped with a layer of wool that we found very plush, as well as a wool and rayon layer that acted 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 if you are looking for a mattress with verified organic sourcing.
How It Performed
The side sleepers on our team found the Birch very suitable, since this sleep position requires a bed that cushions the shoulders and hips while supporting the lower back. Our back sleepers also benefited from the balance of support and cushion. If you tend to overheat during sleep, the breathable latex should help keep you comfortable. 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. When we lay on the bed, the buoyant surface appealed 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 30-day break-in period.
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. The moisture-wicking wool layer is an especially nice touch for sleepers who tend to sweat a lot.

The Eight Sleep Pod 3 is an all-foam smart mattress that allows sleepers to program the bed to certain temperatures at set times. Based on our lab tests, we’ve found it’s a worthwhile option for co-sleepers who have different temperature preferences at night.
What It’s Made of
The Pod 3 is 12 inches thick and constructed with four layers of foam. The top three layers of polyfoam conformed to the body when our testers lay on the bed, while a support core of high-density polyfoam provided a sturdy base. The Active Grid layer covers the bed and contains a grid of tubes. A pump that sits next to the bed pushes water through the grid. You can adjust the temperature for heating or cooling.
How It Performed
The Eight Sleep Pod 3 offers one of the most precise sleep environments out of the hundreds of beds that we’ve tested. Temperature settings range from 55 to 110 degrees Fahrenheit, and different temperatures can be set for each side of the bed. Sleepers can also program the bed to dynamically adjust the temperature throughout the night on its own.
Since the Eight Sleep Pod 3 only comes in one firmness level, medium firm (6), the mattress was best suited for testers weighing up to 230 pounds. These testers found the mix of support and cushioning very comfortable. 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 3 is manufactured in the United States 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 3 warranty lasts 10 years for the foam component and 2 years for the Hub and technology layer.
The Pod 3’s 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.
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.
Watch the video below to see how our test Lab evaluates temperature control in a mattress.

Many people tend to “sleep hot,” or notice themselves wake up in the middle of the night feeling hot and sweaty. Some mattresses exacerbate this problem, while others ease it. Hot sleepers might want to seek out a cooling mattress to help them stay asleep throughout the night.
The term “cooling mattress” is used by many mattress manufacturers to indicate that there is something about the mattress’s construction meant to keep sleepers cool during the night. After testing hundreds of mattresses, we’ve experienced firsthand the many ways in which a mattress can help you sleep cool. The term “cooling mattress” doesn’t refer to any single particular mattress part or system.
Finding a cooling mattress might be your top priority, but you’ll also want to consider other mattress features while shopping. A mattress that keeps you cool isn’t worth much if it causes you discomfort, or isn’t in your price range.
Mattress companies can make many claims and use overblown language when describing their mattresses. Instead of falling for marketing fluff, look past the fancy copywriting to determine what features the mattress has, and if it will meet your needs.
There are multiple types of mattresses sold in the current mattress market. Different types of mattresses are able to keep sleepers cool throughout the night to varying degrees. Generally, mattresses that fall under each category are constructed similarly and share many of the same features.
Of course, there is still plenty of variation within each mattress type. Quality of materials, construction methods, and additional features of specific models will affect how good a particular mattress is for you.
Definition: A hybrid mattress combines aspects of multiple other mattress types. Most hybrid mattresses have a pocketed coil support core 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. Our sleep lab tests show that latex comfort layers can further enhance cooling, but thick memory foam comfort layers could cause a hybrid mattress to trap heat.
Definition: Foam mattresses, also called all-foam or mixed-foam mattresses, are constructed with different types of polyfoam as both the support core and comfort layers. Many sleepers prefer foam mattresses because of the “hug” they generally give the body. The conforming properties of memory foam can relieve pressure and ease pain.
Highlight: Since foam mattresses can trap heat, mattress manufacturers often add in materials with cooling properties. For example, covers with phase change material absorb body heat and transform it to a cooler temperature. Gel, copper, graphite, and charcoal are all infused into polyfoam comfort layers with the intention of cooling.
Definition: Innerspring mattresses also contain a coil support core beneath comfort layers made of polyfoam, latex, or other material. They differ from hybrid mattresses in that the comfort layers are thinner, and the support core makes up the bulk of the mattress’ thickness. As a result, our testers report innerspring mattresses usually feeling bouncier and less conforming.
Highlight: One benefit of innerspring mattresses is that they tend to be naturally cooling due to airflow through their coil layers. Even innerspring mattresses that contain memory foam are cooling since the foam layers are relatively thin. Also, innerspring mattresses are generally less expensive than hybrid and all-foam options.
Definition: Latex has been created from the sap of rubber trees, and it relieves pressure while giving mattresses a springy feel. Some latex mattresses contain only latex in both the support core and comfort layers. Other mattresses incorporate latex layers with other materials, such as coils and polyfoam.
Highlight: 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.
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. We’ve noticed that certain airbeds can become too cool, however. Airbeds with thicker comfort layers will be less likely to have this problem.
Mattresses are constructed with a variety of materials. Some make 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.
Your mattress isn’t the only thing you should focus on when trying to find ways to sleep cool. Instead, consider your entire sleep environment. Many mattress and sleep accessories can help or hinder your efforts toward temperature neutrality.
Figuring out the ideal sleep temperature for your body is a step you can take toward a better night’s sleep. Then, opt for bedding items that will help support your goal of staying cool throughout the night.
There is no single sleep temperature that’s ideal for all people. Experts suggest that most adults’ ideal sleep temperature lies is around 65 degrees Fahrenheit. There are, of course, many people who fall outside of the norm.
Some people will find they prefer a warmer room, while others who sleep hot might find they need their bedroom even cooler. You can experiment with different sleep temperatures to see what feels most comfortable.
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 we’ve noticed it can feel rough to the touch. For that reason, manufacturers often pre-soften linen sheets, or create sheets that are a linen-cotton blend. Tencel lyocell is a fiber made from wood pulp that is naturally moisture-wicking and cooling. Most “bamboo” sheets are made from bamboo-derived lyocell.
Some cooling sheets contain synthetic cooling materials, such as Coolmax fabric or Outlast fibers. Coolmax fabric is a moisture-wicking and breathable polyester. Outlast fibers are temperature-regulating phase change materials that can be combined with other fibers and woven into fabric.
There are many cooling pillows available today. If a traditional down or polyester pillow feels too warm, 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.
Some blankets increase body heat, while others cool. Blankets made of wool, down, fleece, cashmere, and heavy cotton are the warmest and should be avoided by hot sleepers looking to cool off.
Lighter, thinner blankets are cooler than heavier, thicker blankets. Naturally cool blankets are often made of lightweight cotton, a cotton blend, Tencel lyocell, and linen. All of these fabrics are breathable and less likely to trap body heat.
Some blankets are specifically designed to cool, such as those that contain Coolmax or 37.5 technology. Coolmax is moisture-wicking and breathable, while 37.5 fabric is designed to maintain an ideal body temperature.
If you sleep hot on your mattress but aren’t ready to replace it, a mattress topper could help temporarily. A mattress topper is a layer of bedding that changes a mattress’ feel. Mattress toppers come in different thicknesses and materials.
We’ve found that mattress toppers containing 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.
Our testing has repeatedly shown that 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 we’ve found that hybrid beds tend to sleep warmer due to their foam comfort systems. Foam does not permit airflow and often contours closely to the body for reduced airflow even on the surface, making these the warmest mattresses overall. Heat retention also plays a role, as latex has minimal airflow but naturally retains less heat than synthetic foam. However, mattresses are often designed to mitigate these factors.
While the average foam bed may be too warm for a hot sleeper, there are foam beds with unique features meant to prevent heat retention and encourage airflow. Mattress type is important when determining how warm a mattress will be, but it isn’t the only thing to consider.
If your mattress sleeps too warm, but you’re not in the market to buy a new one, you can cool down your bed by purchasing a cooling mattress pad or switching your bedding out for something more breathable. Cooling mattress toppers are available in a wide range of styles, from naturally breathable materials to innovative water-powered technology.
Prices also vary significantly depending on the topper’s design, but even a budget-friendly cooling pad can lead to much more comfortable nights. Bedding also plays a crucial part in how warm your bed is, so warm sleepers should ensure their sheets are made of a breathable material that wicks moisture away from the body.
Many mattresses are constructed with materials intended to promote airflow and retain a low amount of body heat. That said, we’ve noticed that 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.
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.
