Product Details

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. The mattress is designed with a pocketed coil system that promotes steady airflow and helps the mattress maintain a comfortable temperature.

How It Performed

We found the support from the Midnight Luxe’s 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 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 slept quite cool.

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 Midnight Luxe is the middle-of-the-road option, which our testers rated medium firm (6). The mattress 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 zoned pocketed coils, followed by a base layer of high-density foam.

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.

“Even though it’s an all-foam model, the foams in the Nectar Premier have cooling features that help keep the bed from trapping too much heat. The mattress also gives you plenty of bang for your buck, thanks in part to a generous sleep trial that offers lots of time to determine if the mattress will really go the distance for you.” – Jeremy Klein, Senior Product Expert

  • Pros

    1. Mixed foam design greatly alleviates pressure in the joints

    2. Thick foam layers absorb most movement transfer

    3. 365-night sleep trial

  • Cons

    1. Limited edge support can lead to perimeter sinkage

    2. Foam layers may produce strong initial odor

Nectar offers an array of mattresses, but the Premier stood out to our testers for its higher profile and enhanced cooling properties compared to other all-foam models we’ve evaluated in our lab. The thick comfort layer makes this bed an especially good choice for couples who prioritize plush, comfortable sleep surfaces with strong motion isolation.

How It Performed

A top memory foam layer conformed closely to our testers’ bodies, resulting in excellent pressure relief. The mattress also performed well during our motion isolation tests, making this an attractive option for anyone who needs a bed that reduces sleep disturbances from their 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 weighing at least 130 pounds, since they need cushioning in the shoulders and hips but still require support for the lower back.

What It’s Made of

The mattress is 13 inches thick with an all-foam construction that our testers rated medium firm (6). The topmost layer consists 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 foam, followed by a 7-inch base layer of high-density polyfoam that stabilizes the mattress.

Nectar ships free of charge within the contiguous U.S. The Premier comes with a generous 365-night trial and lifetime warranty.

“Three of our field testers have slept on a WinkBed for over a year and they all praise the exceptional support from the sturdy coils. Others on our testing team agree that the adaptive foam cushioning excels at cradling without allowing uncomfortable sinkage.” – Colin Simpson, Research Manager

  • Pros

    1. Foam layers adapt closely to the body, improve spinal alignment, and alleviate pressure

    2. Zoned coils protect the perimeter and promote easy movement across the surface

    3. Breathable Tencel cover and strong internal airflow help the mattress stay cool

  • Cons

    1. Firmer models offer limited motion isolation

    2. Thick profile may require new sheets with deep pockets

Product Details

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.

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 our 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 effectively, 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.

What It’s Made of

The WinkBed is available in four firmness levels: medium soft (4), medium firm (6), and firm (7), as well as the WinkBed Plus option with a firm (8) feel. Standard WinkBed models 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 zoned latex layer instead of a second polyfoam layer. 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.

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

“We didn’t notice excessive heat retention in the Brooklyn Bedding Aurora Luxe when we performed our temperature tests in the lab. I’ve personally slept on this model for around 4 years and recommend the bed for anyone who enjoys a little bit of cradling from foam but still needs the sturdy support of coils.” – Jeremy Klein, Senior Product Expert

  • Pros

    1. Available in three firmness options

    2. Airflow through the pocketed coil support core keeps sleepers cool

    3. Foam comfort layers isolate motion

  • Cons

    1. Strong initial off-gassing odor is likely

Product Details

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 different types of sleepers, and the hot sleepers on our team appreciated the Aurora Luxe’s cooling features.

How It Performed

The Aurora Luxe is designed with comfort in mind – just soft enough to cushion our pressure points, 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 cover fabric and CopperFlex foam are both infused with TitanCool, a phase change material meant to wick moisture from the body, dissipate heat, and maintain a neutral temperature. The coils also enable air to circulate and keep the bed cool.

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. You can opt for an additional foam layer in the comfort system. This layer, known as the “Cloud” pillow-top, provides extra cushioning and may make the mattress feel slightly softer compared to models that don’t feature this layer.

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 Saatva Latex Hybrid is ultra-responsive, so it always feels like you’re lying on the mattress instead of in it. There’s also a lot of airflow throughout the bed, thanks to the coils and naturally breathable materials. I find it provides a supportive, cool night’s sleep.” – Logan Foley, Managing Editor

  • Pros

    1. Breathable wool, latex, cotton, and coils help facilitate airflow

    2. Components hold GOTS and GOLS certifications

    3. All orders include a year-long sleep trial

  • Cons

    1. Responsive design can lead to sleep disruptions for couples

    2. Some side sleepers prefer mattresses with more cushioning

Product Details

Since uneven support and excessive sinkage can exacerbate pain from poor sleep posture, some sleepers require a mattress with extra reinforcement for their bodies that keeps them on an even plane. The Saatva Latex Hybrid has a luxury latex-over-coil design that delivered outstanding stability during our testing without sacrificing comfort or pressure relief.

How It Performed

The Latex Hybrid’s responsiveness and medium firm (6) feel best suited our back and stomach sleepers weighing between 130 and 230 pounds, but most sleepers who use these positions should feel comfortable. The latex offers gentle cradling to relieve pressure points, while the coils keep the body from sinking excessively.

Temperature control was one of the mattresses main strengths. The breathable cover and comfort materials naturally retain less heat, and the coil system ensures steady internal airflow. As a result, our heat guns detected minimal heat retention during testing. We also found the mattress to be a great choice for couples who prefer a bouncier surface for sex. Couples should feel comfortable moving across the full surface with little to no sinkage along the edges.

What It’s Made of

A layer of GOTS-certified organic wool gives the surface a bit of cushioning while acting as a natural fire barrier. Underneath is a layer of zoned Talalay latex that offers enhanced support to the lower back while cradling pressure points in the hips and shoulders. This layer also prevents your body from sinking too deeply into the coils.

Zoned pocketed coils make up the support core. Thicker coils are zoned underneath the midsection to prevent uncomfortable sagging and help you maintain healthy sleep posture. The coils rest on a base layer made from a blend of organic cotton and GOTS-certified organic wool. The mattress is encased in a breathable organic cotton cover.

All Saatva customers in the contiguous U.S. qualify for free White Glove delivery, which includes full assembly 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 Leesa Sapira Chill Hybrid pairs a thick foam comfort system with a sturdy coil base, resulting in a balanced mattress with excellent cushioning for sleepers who prioritize pressure relief. Available in three firmness options, it’s a suitable pick for couples who need a bed that can accommodate a range of sleep preferences.

How It Performed

You can choose between three firmness levels that translate to medium (5), medium firm (6), and firm (7) on our 10-point firmness scale. Regardless of the firmness level you pick, the mattress has a 14-inch profile with substantial foam layers that cradle your body and offer very good pressure relief for areas like the shoulders, hips, and spine. Air circulation in the coils, a gel infusion in the top foam layer, and cooling fibers in the cover all help keep the surface at a comfortable temperature.

Side sleepers in lighter weight categories preferred the softer models while those in heavier weight groups gravitated toward the firmer models. Back sleepers up to 230 pounds generally gave higher marks to the two firmer options, and stomach sleepers in the same weight category gave their highest marks to the firm model.

What It’s Made of

The Leesa Sapira Chill Hybrid has a polyester blend cover infused with cooling fibers that help mitigate heat retention. Two inches of polyfoam are quilted into the cover for even cushioning across the surface. This is followed by three additional foam layers, one of which is memory foam, that generate close contouring. The layers grow progressively denser to prevent you from sinking into the support core, which contains pocketed coils. The coils are zoned to enhance support in the lumbar area.

Leesa ships mattresses for free to all 50 states. Each bed comes with a 100-night sleep trial and a 10-year warranty.

“The memory foam in the Nolah Evolution 15 gives you a decent amount of hug that really helps with pain points. Thankfully it never gets too hot, due to a solid base of zoned coils that provides plenty of airflow and support.” – Mark Horiuchi, Lead Product Tester

  • Pros

    1. Euro-top quilted with foam gives the surface a plush feel

    2. Zoned pocketed coil support core provides targeted support to the midsection

    3. 15-inch profile

  • Cons

    1. Thick profile may necessitate deep-pocket sheets

Product Details

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 sleepers with back pain and other people who experience painful buildup at night.

How It Performed

The 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 firm (8) option, since this sleep position requires a flat, supportive surface for proper spinal alignment.

What It’s Made of

At 15 inches thick, the Nolah Evolution 15 is a high-profile mattress with an adaptive comfort system. The Euro-top cover is quilted with foam, followed by a comfort layer of proprietary AirFoamICE foam. When our testers were lying on the bed, they found these two comfort layers offered above-average cushioning for a hybrid. 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.

The Evolution comes in all six standard sizes, as well as a split king size for adjustable beds. Nolah ships mattresses for free within the contiguous U.S. Customers receive a 120-night sleep trial and may return the bed for a full refund after an initial 30-day period. The Evolution 15 comes with a lifetime warranty.

“The Bear Elite Hybrid has a cover made of Celliant-blend fabric, which can help regulate temperature throughout the night. The strong temperature regulation and the versatile hybrid design make this a strong fit for co-sleepers with different sleep preferences.” – Logan Foley, Managing Editor

  • Pros

    1. Three firmness levels to accommodate different sleep positions and body types

    2. Celliant-blend cover engineered to cool the surface and dissipate heat

    3. Zoned transitional layer provides enhanced reinforcement for the midsection

Product Details

Most mattresses that earn high ratings in our motion isolation tests have adaptive foam layers, 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 prevent movement transfer when your partner changes positions at night, but we found the specialized cooling cover facilitates airflow while you sleep.

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, as well as 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 releases heat from the surface, as well as steady air circulation through the coil system and the breathable, copper-infused memory foam comfort layer. The Elite Hybrid’s other strengths vary by firmness level. The two softest models performed well during our 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.

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 gently cradling 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 lied along 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.

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.

“I’m a side sleeper who’s been using the Layla Hybrid for several years, and I’ve found the foam layers are really great at cushioning my shoulders and hips to prevent them from getting sore. I tend to sleep hot, but the airflow through the coils keeps the temperature very comfortable.” – Tom Ryan, Head of Product Testing

  • Pros

    1. Reversible design with two distinct feels

    2. Pressure-relieving foam comfort system infused with copper gel intended for cooling

    3. Reinforced perimeter enhances edge support

  • Cons

    1. Heavy design may be difficult to lift and flip

Mattresses with foam layers typically trap body heat since they adapt so closely to the body. The Layla Hybrid pairs cooling technology with steady airflow through the coil system, earning it high marks in our temperature control tests.

How It Performed

The mattress has a reversible design with a different feel on each side: medium soft (4) and firm (7). Most of our testers found a side that felt comfortable, regardless of their sleeping positions or body types. The softer side’s thick cushioning earned its highest ratings from our side sleepers weighing up to 230 pounds, as well as back and stomach sleepers weighing under 130 pounds. Meanwhile, the firmer side offered even contouring enjoyed by back and stomach sleepers weighing at least 130 pounds.

Both sides earned balanced reviews across our testing criteria with only slight differences in performance. The softer side’s thicker comfort system absorbed more motion, while the firmer side slept slightly cooler. Both excelled in our edge support tests, thanks to the reinforced perimeter.

What It’s Made of

Both sides feature a mixed-foam comfort system, but the softer side’s foam layers are slightly thicker than on the firmer side. They begin with an adaptive memory foam layer that closely contours to the body to relieve pressure. This layer is infused with copper gel meant to conduct and dissipate heat. Underneath is a polyfoam transitional layer that acts as a buffer between the comfort system and the coils.

Pocketed coils make up the shared support core, offering targeted support to the midsection to reduce uncomfortable sagging. A reinforced perimeter prevents you from sinking when lying or sitting near the edges. The cover is made from a stretchy polyester, rayon, viscose, and poly-lycra blend.

Layla ships free to customers living in the contiguous U.S. The Layla Hybrid is backed by a 120-night sleep trial and a 10-year warranty against structural defects.

“The Birch has a bouncier feel that gives you a good amount of contouring without trapping you in the bed. The latex, wool, and cotton layers are all naturally cool, so this bed also excels at regulating temperature. I’m a fan of natural and organic materials, so the eco-friendly construction is the cherry on top for me.” – Tom Ryan, Head of Product Testing

  • Pros

    1. Breathable organic latex and cotton help regulate temperature

    2. Talalay latex comfort system gently cradles the body to relieve pressure

    3. Responsive design helps you move across the surface

  • Cons

    1. Couples may experience sleep disturbances due to bouncy surface

Product Details

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.

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. The buoyant surface should also appeal to sleepers who prefer the feeling of sleeping “on” the bed rather than “in” it.

What It’s Made of

The Birch Mattress is constructed with Talalay latex that cushioned pressure points during testing but also delivered enough pushback to 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 acts as a fire barrier. The bed is encased in a cotton cover with 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.

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.

Watch our video below to learn more about our lab’s top picks for cooling mattress.

Expert Tested. Sleeper Approved.

Over the past eight years, our Seattle-based Test Lab has performed hands-on tests on more than 4,000 sleep products — and nearly 2,000 of them are mattresses. 

As product experts, we stay up to date on the latest news in sleep science and product trends. We use this knowledge to fuel our data-backed recommendations. Many of our testers have worked directly with mattress manufacturers and visited actual mattress factories. On occasion, a sleep health expert might stop by to tweak a firmness rating.

When we test a mattress, we collect data across six major performance categories and combine these results with real-world feedback. We use tools and tech to monitor features like heat retention, motion isolation, and pressure mapping. In order to ensure our findings are inclusive of all sleepers, our team consists of people with varying body types and sleep positions.

Mattresses aren’t one-size-fits-all. The perfect bed for you is going to depend on general points like your body weight and sleeping position, as well as unique points like if you have back pain, if you sleep hot at night, or if you just like the feel of latex over memory foam. Our goal at the Test Lab is to help take the guesswork out of your mattress-buying process.

What Makes a Mattress Cooling?

Certain mattress materials provide consistent cooling by promoting airflow, dissipating heat, and wicking moisture away from your body. Firmness level also plays a role because mattresses that sink more tend to trap more heat than those with stronger support systems. We’ll discuss the best mattress types, materials, and firmness levels for temperature control below.

What to Look for in a Cooling Mattress for Hot Sleepers

If you’re a hot sleeper in search of a cooling mattress, there are a few factors to take into account while you shop. Consider the following.

What Do You Need From Your Bed?

People who reside in hot or humid climates, are prone to night sweats, are pregnant, or have heat-inducing medical conditions can all benefit from a cooling mattress.

Mattress Material

Some materials regulate heat better than others. Cooling begins with the top layers of the mattress. Open-cell foam and ventilated latex both promote air circulation directly below the sleep surface and dissipate heat in the process. Memory foam, on the other hand, tends to absorb and trap heat, whichcan be problematic for hot sleepers.

“I tend to overheat at night, especially when it’s warm. Investing in a cooling mattress has definitely helped alleviate this problem. The airflow through the coil layer provides a noticeable difference compared to the all-foam model I slept on before.”
Lauren Fountain
Senior Product Editor

Support materials are equally important. Coil systems and ventilated latex base layers circulate air throughout the interior of the  mattress to help maintain a comfortable temperature, whereas solid foam stores the heat retained from the comfort layers. Your mattress cover plays a role in cooling as well. Breathable fabrics such as cotton, viscose derived from bamboo, Tencel, and cashmere regulate temperature better than synthetics like polyester.

Cooling Technology

Mattresses can also build on cooling qualities by leveraging technology. Passive cooling refers to technology that promotes breathability and temperature regulation, like the use of phase change material that releases body heat on contact or gel or copper infusions in the bed’s foam layers. Some mattresses use active cooling technology with specialty covers that physically change the temperature of your sleep surface. These mattresses tend to be more expensive, but may be a solid investment if you’re losing sleep from excessive heat.

Contouring and Firmness

Contouring refers to how your mattress conforms to your body. Some mattresses contour closely to distribute your weight, align your spine, and alleviate pressure in the shoulders, lower back, and hips. In the process, you may sink deeply into the surface and retain moreheat. 

Firmer mattresses that don’t contour as closely or sink as deeply will provide more surface-level airflow. Our testing team has found that mattresses with a firmness level of medium firm (6 on our 10-point scale) or higher tend to sleep significantly cooler than models rated medium (5) or softer.

Quick Relief Tips for Hot Sleepers

If you’re optimizing your sleep space for temperature control, your mattress isn’t the only factor to take into account. Certain accessories can also reduce heat retention while you sleep.

Invest in a Cooling Mattress Topper

Toppers are layers of cushioning material intended to make your sleep surface softer or firmer. Some toppers are made of breathable materials for the added effect of keeping your mattress cool. The best cooling mattress toppers contain materials such as gel-infused foam, ventilated latex, and wool.

Use Breathable Bedding and Pajamas

Sheets, pillowcases, and blankets play an important role in thermoregulation because they come into direct contact with your skin. We’ve found the best bedding for temperature is made of breathable materials like cotton, linen, viscose derived from bamboo, and Tencel. Likewise, pajamas made from these fabrics can also help you stay cool in bed. Sleeping naked can also help cool your core temperature.

Block Light and Allow Air to Flow

Hot sleepers can find relief at night by controlling their bedroom temperature. Blackout curtains that block light from entering the room, a bedside fan or air conditioner unit, and a foundation that promotes airflow beneath your mattress can all be helpful additions to your sleep environment.

Frequently Asked Questions

Which mattress type is best for cooling?

Our tests have shown hybrid and innerspring mattresses offer the most consistent cooling because air flows freely through their coil systems. These mattresses also tend to be firmer and don’t contour as closely. All-latex models with ventilated layers and moisture-wicking wool fire barriers have also performed well during temperature control tests.

Which mattress types should hot sleepers avoid?

We’ve found that all-foam mattresses tend to retain and trap heat. This is especially true of models with thick, high-density memory foam layers. Some hybrids we’ve tested with the same comfort layer materials also sleep fairly hot despite steady airflow in their coil systems, especially models that rate between soft (3) and medium (5) on the 10-point firmness scale.

What is the best way to cool down a mattress?

If your mattress sleeps hot and you don’t want to invest in another model, try using other sleep products that excel at temperature control. A cooling mattress topper can be effective, especially those containing water tubes that physically change the temperature of your sleep surface. Cooling pillows, sheets, and mattress pads can also help you stay comfortable in bed.

What is the best temperature for sleep?

Preferences vary from person to person, but studies have shown the most comfortable sleeping temperature for adults falls between 60 and 68 degrees. This range aligns with natural temperature drops that occur during your sleep cycle and prevents overheating. Make sure to adjust your thermostat to ensure a comfortable bedroom throughout the night.

How do cooling mattresses work?

Cooling mattresses regulate your temperature by minimizing heat retention on the surface, promoting airflow throughout the interior, and wicking moisture away from your body. The mattress’ comfort layers, support core, and cover all play a role in temperature control. Most cooling mattresses are firmer and don’t contour closely to the body.
