Best Cooling Mattress for Hot Sleepers

Do you find yourself waking up drenched in sweat or throwing the blankets off in the middle of the night? Many people sleep hot due in part to their mattresses. Our bodies experience natural temperature shifts throughout the day and night. This cycle includes a peak in the early evening, followed by a gradual cool-down that lasts until you wake up in the morning. As your body loses heat, your mattress and bedding may absorb and trap excessive warmth. All of this can obviously have a negative impact on your overall sleep quality and duration.

There are different strategies for maintaining comfortable sleeping temperature, such as using breathable sheets or a bedside fan, and wearing little to nothing to bed. For many, the most effective remedy for sleeping hot is to choose a mattress with consistent temperature neutrality. Some beds are cool and breathable due to their material components, while others are equipped with special heating and cooling features.

Our six best cooling mattress picks are outlined below. Each selection is based on feedback from verified mattress owners and our own product research. Further down, we'll explore why some mattresses sleep cooler than others and discuss some additional strategies for keeping your bed cool.

eight sleep pod

Highlights:

  • Customizable temperature controls
  • Integrated sleep-tracking technology
  • Pressure-relieving foam layers

Ideal For:

  • Sleepers who like to control their bed's temperature
  • Side and back sleepers
  • People who enjoy tracking sleep data

Our best mattress for hot sleepers picks begin with the Eight Sleep Pod, an all-foam mattress that offers some of the most sophisticated temperature-regulating technology available. The Pod's cover is equipped with body sensors, and it connects to a reservoir of water with a network of thin plastic tubes. You can adjust the bed's temperature anywhere between 55 and 115 degrees Fahrenheit (12 to 46 degrees Celsius). The Pod heats and cools each side of the bed by bringing the water in the reservoir to a certain temperature, and then funneling it to the cover.

Temperature adjustments are made using the Eight Sleep app, which is compatible with any smartphone or tablet device. You can also use the app to track sleep data points, such as sleep cycle breakdowns, heart rate, and wakeup times. The app has white noise and thermal smart alarm functions, as well. The mattress itself is constructed with comfort layers of polyfoam and memory foam over a dense polyfoam base. The top layers offer a medium (5) feel and they conform somewhat closely to support your spine and reduce pressure points – especially if you sleep on your side and/or back.

The Pod is fairly expensive given its advanced features and customization level. If you live in the contiguous U.S., you'll receive free ground shipping. The Pod is backed by a 100-night sleep trial, along with a 10-year warranty for the mattress and a 2-year warranty for the technology layer.

Layla Mattress

Highlights:

  • Flippable design offers two distinct firmness levels
  • Copper-infused memory foam helps maintain cool surfaces
  • Both sides absorb motion and isolate transfer

Ideal For:

  • People who prefer a medium soft and/or firm mattress feel
  • Couples
  • Value seekers

Our next pick, the Layla, is one of the best cooling memory foam mattress models on the market today. The Layla is a flippable bed. One sleep surface has a medium soft (4) feel, while the other surface is firm (7-8). Both surfaces feature memory foam infused with copper, which helps the material absorb less heat from your body and resist excessive warmth. As a result, the Layla sleeps much cooler than many of its all-foam competitors.

Each surface of the mattress is best suited to different types of sleepers. The medium soft side conforms very closely to support the spine and alleviate pressure points. Side sleepers receive ample padding for their shoulders and hips, which helps to ensure even spinal alignment. Back and stomach sleepers who weigh less than 130 pounds may also find this surface comfortable due to its deep contouring. People who weigh at least 130 pounds, on the other hand, will probably prefer the firm side due to its stronger support. This is particularly true for back and stomach sleepers in this weight group because they often experience too much sink on softer beds.

The Layla has a very affordable price-point for a memory foam model, and customers in the contiguous U.S. also qualify for free ground shipping. The mattress comes with a 120-night sleep trial, as well as a lifetime warranty for added peace of mind.

Purple Hybrid

Highlights:

  • Signature Purple Grid comfort layer promotes surface cooling
  • Above-average motion isolation
  • Comfortable balance of contouring and responsiveness

Ideal For:

  • Back and side sleepers
  • Couples
  • People who experience pressure points but find memory foam too soft

The Purple Hybrid is one of the coolest sleeping mattress models available today. largely due to its Purple Grid, a proprietary comfort layer that consists of hyperelastic polymer material molded into an open grid shape. The Purple Grid conforms to the body much like memory foam but also feels fairly responsive, so you won't sink beneath the surface and become too warm. The open grid structure also promotes steady airflow across the surface for added breathability.

The Purple Hybrid also has a pocketed coil support core that circulates strong air currents. This allows the interior of the mattress to maintain a comfortable temperature. Most hybrids sleep fairly cool for this reason, but thanks to its pocketed coils coupled with the special comfort layer, the Purple Hybrid offers standout temperature neutrality even compared to similarly constructed models. Additionally, the Purple Hybrid is a great choice if you experience pressure points in the shoulders, hips, and other sensitive areas. The bed has a medium firm (6) feel, so you'll feel a combination of body-conforming and even support.

Compared to other hybrid models, the Purple Hybrid has a very reasonable price-point. The company will also ship the mattress for free anywhere in the contiguous 48 states. The hybrid is backed by a 100-night sleep trial and a 10-year warranty.

Winkbed Plus Mattress

Highlights:

  • Gel-infused comfort layer and breathable cover
  • Zoned coils provide very strong edge support
  • Four firmness options, including a specialized feel for people over 200 pounds

Ideal For:

  • Sleepers who like a very responsive mattress feel
  • People who prefer thicker mattresses
  • Those who have a hard time getting in and out of bed

Another hybrid model that sleeps very cool is the Winkbed. Standard WinkBed models are constructed with a comfort layer of gel-infused polyfoam, followed by a transitional layer of pocketed microcoils. The comfort foam resists heat build-up and won't trap warmth like the foams found in many competing beds, while the coils promote steady airflow near the surface of the bed. The cover is also made from Tencel, an exceptionally breathable fabric partially derived from plant-based materials that helps wick away moisture, and the pocketed coil support core circulates air for extra cooling.

The standard WinkBed is available in three firmness options: medium soft (4), medium firm (6), or firm (7-8). You can also select the WinkBed Plus, a firm model specifically designed for people who weigh more than 200 pounds. This model features a latex layer in place of the microcoils, which makes the bed feel very responsive. The latex is ventilated for added airflow, as well. No matter which firmness you choose, the WinkBed should provide enough cooling to keep you comfortable throughout the night. Support is another strong point. The WinkBed's support core is zoned with thicker coils reinforcing the edges against sinkage while thinner coils cradle your body.

The WinkBed's price-point is very reasonable compared to other hybrids, and the company will ship for free anywhere in the contiguous U.S. The mattress comes with a 120-night sleep trial and a lifetime warranty.

dreamcloud mattress

Highlights:

  • Pressure-relieving memory foam comfort layer
  • Exceptional support with little to no sagging
  • Very long sleep trial and lifetime warranty

Ideal For:

  • Sleepers who prefer very supportive mattresses
  • People who weigh at least 130 pounds
  • Those who enjoy sleeping on thicker beds

The DreamCloud is a great cooling mattress that won't break the bank. The bed is constructed with a gel-infused memory foam comfort layer that feels fairly breathable and doesn't trap too much body heat. A support core of thick pocketed coils also promotes strong airflow to help the mattress maintain a comfortable temperature. The mattress has a medium firm (6) feel, so you won't sink too deeply into the mattress – a common cause of sleeping hot.

In addition to hot sleepers, the DreamCloud is optimal for people who frequently feel pressure points. The memory foam cushions the hips and shoulders without sagging. This allows side sleepers to experience even spinal alignment while back and stomach sleepers receive adequate pressure relief without losing support. People who prefer very responsive mattresses – as well as couples who prefer bouncier beds for sex – should also find the DreamCloud very comfortable. The edges are well-supported, allowing you to get in and out of bed easily.

Compared to other hybrid models, the DreamCloud is very inexpensive. Free shipping is also available within the contiguous U.S. The mattress comes with a 365-night sleep trial, giving you up to one year to decide whether or not you want to keep the mattress, as well as a non-prorated lifetime warranty.

Avocado-Green-Mattress

Highlights:

  • Durable latex hybrid construction
  • Certified organic materials
  • Contouring yet responsive feel

Ideal For:

  • Sleepers who prefer a mix of conforming and support
  • Those seeking a long-lasting mattress
  • Eco-conscious shoppers

Latex hybrids generally sleep very cool and are great options for hot sleepers. The Avocado Green is a notable standout for a few reasons. For one, it is constructed with certified-organic latex in the comfort and transitional layers. Organic latex contains a relatively low amount of chemical fillers, which allows the material to provide great temperature neutrality, and the Avocado Green's latex layers are ventilated to promote steady airflow near the surface. The cover is also made from a breathable, moisture-wicking blend of organic cotton and natural wool.

The pocketed coil support core generates strong air currents for added temperature regulation. The coils are also very thick to keep you on an even plane and prevent excessive sagging along the edges. These strong coils, coupled with the naturally durable cover and latex layers, give the Avocado Green an exceptionally long expected lifespan. The standard Avocado Green has a firm (7-8) feel. You can customize your mattress with a pillow-top that provides extra body-cushioning. The pillow-top creates a medium feel that may be more suitable for people who weigh less than 130 pounds – side sleepers in particular.

Considering the Avocado Green is an organic latex hybrid – an expensive mattress type – its price-point is very reasonable with or without the pillow-top. Avocado also ships for free to all 50 states. The mattress is backed by a 365-night sleep trial and a 25-year warranty.

How to Find a Mattress That Will Keep You Cool

How cool or warm a mattress sleeps primarily depends on the specific components used in its cover, comfort layers, and support core. If you're a hot sleeper, then you should narrow your mattress search to models built with breathable layers that promote temperature regulation and won't trap too much body heat. Below, we'll explore the coolest mattress materials, along with a few strategies for maintaining a comfortable sleep temperature.

What Is a Cooling Mattress?

The term "cooling mattress" refers to any bed that promotes temperature neutrality and won't sleep too warm. Some mattresses offer active cooling, meaning they are equipped with features that actually change the surface temperature. One example of an active cooling mattress is the Eight Sleep Pod listed above, which is designed with a network of water tubes that can adjust each side of the bed to anywhere between 55 and 115 degrees Fahrenheit.

Other mattresses provide passive cooling. These beds cannot be set to a specific temperature, but they contain breathable materials and components that help the bed remain cool and comfortable throughout the night.

What to Look for in a Mattress

When shopping for a new mattress, you can use certain qualities and factors to determine how warm or cool a bed will sleep. One thing to keep in mind: some mattress companies may exaggerate a bit when it comes to mattress performance, and may tout some models for superior temperature neutrality when they actually sleep somewhat hot. We encourage you to focus on the following qualities – and not marketing jargon – to evaluate new mattresses for cooling ability.

  • Price: The average mattress costs between $1,500 and $1,900 in a queen size. Mattresses with active cooling components – such as the Eight Sleep Pod – tend to be somewhat expensive. Models with coil systems, ventilated comfort layers, and other passive cooling components are usually much more affordable.
  • Sleeping Position: If you sleep on your side, then the ideal mattress will cushion the shoulders and hips to align your spine and alleviate pressure. For this reason, most side sleepers prefer softer beds. If you sleep on your back or stomach, you'll probably need a firmer mattress that won't sag too much around your midsection.
  • Mattress Type: Innersprings and hybrids tend to be the coolest mattress types because their coil systems promote steady air circulation, which helps the bed maintain a comfortable temperature. Latex mattresses may also sleep cool, especially if the latex layers are ventilated. All-foam mattresses often sleep the warmest because the foam absorbs and traps body heat.
  • Contouring: Beds that conform closely to the body generally provide the best pressure relief. However, deep contouring can also cause you to feel too warm because you'll experience less surface airflow. Responsive mattresses that keep the body on an even plane usually sleep cooler by comparison.
  • Quality Materials: High-quality materials can drive up the price of a mattress, but this does not mean the materials sleep cool. Take high-density memory foam. Although this material conforms very closely and is fairly durable, it also tends to absorb and trap more body heat than lower-density foam.
  • Firmness Level: Beds with soft or medium soft feels often sleep the warmest because they conform closely to the body, which can lead to more body heat absorption and restricted surface airflow. The coolest mattresses also tend to be the firmest because your body won't sink as deeply.
  • Pressure Relief: The best mattresses for pressure relief will conform to your body and support your spine without sagging around the midsection too much. Beds with thick layers of memory foam and/or latex tend to alleviate the most pressure, but your body type and sleep position may also play a role.
  • Edge Support: Beds with strong perimeter support won't sink as much when you sit or sleep along the edges. If the perimeter support is weak, then you won't feel as secure sleeping near the edges and may be confined to the center of the bed. Hybrids and innersprings usually offer the best edge support thanks to their strong coil systems.
  • Noise: The noise potential of a mattress is typically linked to its support core materials. Some materials, such as foam and latex, are completely silent when bearing weight. Coils may squeak and creak on occasion, and the motorized chambers found in airbeds may produce a soft whirring when you adjust the firmness.
  • Temperature Regulation: How warm or cool a mattress sleeps largely depends on its material construction. Components that help regulate temperature include covers made from breathable fabrics, ventilated comfort layers that promote airflow near the surface, and coil systems that circulate air currents.

What Mattress Materials Are Coolest?

Pay close attention to product specs when choosing a new mattress. Some materials are more breathable and better at regulating temperature than others, and these components can make the difference between a bed that sleeps cool and one that traps body heat.

  • Coils: Coil support systems are found in innersprings and hybrids. Some beds also feature microcoils that act as comfort or transitional layers. Coils promote strong airflow, and this can help the mattress maintain a cool and comfortable temperature.
  • Latex: Latex is fairly breathable compared to polyfoam or memory foam. Latex that is ventilated with tiny holes can be particularly effective at promoting airflow near the bed's surface. Additionally, organic and natural latex both contain a limited amount of chemical fillers, so they tend to sleep cooler than blended or synthetic latex as a result.
  • Gel-infused foam: Cooling gel beads may be infused into polyfoam or memory foam to help the material resist heat build-up. Some sleepers find gel-infused foam sleeps noticeably cooler than standard foam, but others notice little to no difference.
  • Standard memory foam: Standard memory foam has a low density – 4 PCF or less, in most cases. This material absorbs less body heat than higher-density memory foam, allowing it to feel cooler and more breathable. That said, even low-density memory foam has the potential to trap some heat.
  • High-density memory foam: High-density memory foam has a lot of benefits, including close conforming, enhanced pressure relief, and a long lifespan. However, the material sleeps very warm because it traps a large amount of body heat. Many owners of mattresses with high-density memory foam report uncomfortable heat retention.
  • Standard polyfoam: Polyfoam is a bit more breathable than memory foam, and the material's temperature tends to improve as the density decreases. Many all-foam beds have low-density polyfoam comfort layers. They might still trap some heat, but many sleepers find these mattresses sleep reasonably cool.
  • High-density polyfoam: High-density polyfoam – like high-density memory foam – captures a fair amount of body heat. This material is rarely used in comfort layers because of its extra-firm feel, but all-foam beds with high-density polyfoam support cores tend to sleep the warmest among all mattress types.

How to Keep Your Bed Cool

A cooling mattress can be a very beneficial investment, especially if you sleep hot. There are additional measures you can take if your temperature tends to spike in bed. We'll discuss ideal sleep temperatures along with bedding accessories that can help you stay cool throughout the night.

What Is the Best Temperature for Sleep?

Although everyone has individual preferences regarding comfortable and uncomfortable temperatures, many experts agree the ideal sleep temperature for most adults falls between 60 and 67 degrees Fahrenheit (15 to 21 degrees Celsius). We recommend presetting your bedroom thermostat between 60 and 67 degrees prior to getting into bed. This way, the room will already be at a comfortable temperature when you turn off the light.

Our bodies are hard-wired to feel warmer and cooler during different times of the day. Your temperature will peak in the late afternoon or early evening, and then gradually decrease throughout the night. Exposure to excessive warmth or cold before sleep can interfere with this natural temperature regulation cycle.

Use Breathable Sheets

Sheets can play a major role in your temperature regulation during the night. Some sheets consist of breathable, lightweight fibers that are ideal for warmer times of the year. Other sheeting materials provide insulation and warmth, making them better suited to colder climates. Weave is another important consideration, as some weaves promote more breathability than others.
Go for:

  • Percale weaves: Percale refers to a tight, one-over-one-under weave that yields crisp sheets and pillowcases. Many liken the material's feel to men's dress shirts. Percale bedding is also very lightweight, which makes the material very breathable and well-suited to summer months.
  • Breathable fibers (cotton, linen, bamboo): Sheets made from natural fibers like cotton and linen tend to be highly breathable, especially when constructed with a percale weave. Some semi-synthetic fibers can also be breathable, including Tencel lyocell and bamboo from rayon – both of which are derived in part from plant-based materials.

Avoid:

  • Thick weaves: Sateen is a four-over-one-under weave that produces ultra-soft sheets. Unlike percale, sateen is not particularly breathable and is best suited for insulating against colder weather.
  • Heat-retaining fabrics: Polyester, a synthetic material, tends to trap more body heat than cotton, linen, and other natural fibers. This depends somewhat on the weave, as percale polyester sheets are usually more breathable than sateen polyester sheets, but you may want to consider another sheeting fabric altogether if you are a hot sleeper.

What Kinds of Pillows Sleep Cool?

Like mattresses, pillows have the potential to absorb and trap body heat because they come into direct contact with your body. Thankfully, some pillow cover and fill materials are much more breathable than others.

Go for:

  • Breathable covers and fills: The ideal cooling pillow features breathable cover and fill materials that promote steady airflow. The best pillow fills for temperature neutrality include shredded latex, feathers, and buckwheat hulls. Organic cotton, rayon from bamboo, and Tencel lyocell are regarded as some of the coolest cover materials.
  • Cooling foams and materials: Solid-foam pillows often trap heat, but pillows containing shredded memory foam are often more breathable. Foams infused with gel beads, copper, graphite, and other cooling materials may resist heat build-up even better.
  • Phase-change material: Phase-change material, or PCM, is often infused into pillow covers. The PCM will absorb heat from your body until the cover reaches a certain temperature. This allows the pillow to maintain a cool surface regardless of how hot you feel.

Avoid:

  • Thick, dense foams: We've already discussed how high-density foam in mattresses can absorb a lot of body heat. The same is true of pillow containing high-density memory foam or polyfoam – especially if the fill consists of a single piece, rather than shredded foam.
  • Fills and covers that retain heat: In addition to memory foam, down – the soft inner plumage from ducks and geese – can also retain heat from your body and feel uncomfortably warm. You may also want to avoid pillows with polyester covers if you tend to sleep hot.

Make Sure Your Blankets Aren’t Too Thick

The blanket – or blankets – you sleep with can also contribute to hot sleeping, especially if these layers are thick, heavy, and constructed from insulating materials. As with sheets, we recommend rotating blankets throughout the year in order to stay cool in hotter climes and warm when the temperatures drop.

Go for:

  • Breathable weaves and styles: Lightweight and breathable blanket weaves promote the most airflow. Some blankets have open-knit construction that allows air to circulate through holes between the yarns. If you live in an area that has cooler summers, then an all-season blanket might be the best option. These blankets often have down fill, and some feature removable components that allow you to shed some loft during hotter months.
  • Natural fabrics and covers: Natural fibers such as cotton, linen, and silk often produce the most breathable blankets. Wool also sleeps fairly cool and has natural moisture-wicking properties, as does rayon from bamboo, which is derived in part from bamboo fibers.
  • Lightweight fills: Heavier blankets tend to feel warmer regardless of whether or not they contain breathable fill materials. Down blankets are particularly lightweight. Although the material is not very breathable, these blankets won't trap and insulate heat like those with heavier fills.

Avoid:

  • Weaves and styles that trap heat: Blankets with tight, multi-sided weaves may restrict breathability, trapping heat in the process. If you're a hot sleeper, avoid heavy blankets designed to provide insulation – especially during warmer periods of the year.
  • Thick, heat-retentive materials: Some blankets have heat-retentive cover and fill materials that make them assets during the winter months, but bothersome when temperatures rise. These include polyester and down alternative.

Try a Cooling Mattress Topper

A mattress topper is a layer of padding that rests on top of your bed's surface. Toppers are designed to make the mattress feel softer or firmer, depending on your preferences. They can also help you preserve the bed's surface and extend its overall lifespan – though toppers don't last as long as mattresses, and they need to be replaced more frequently.

Because a topper is essentially an additional comfort layer, it may affect how hot or cool you feel in bed.
Go for:

  • Natural fills and fabrics: Wool gets a bad rap. Due to its insulating properties, many assume wool sleeps excessively warm. However, this material is actually ideal for many hot sleepers because it wicks away moisture during hotter times of the year. Down/feathers and latex are other examples of cooling topper materials.
  • A temperature-regulating topper: Most toppers measure 2 to 5 inches thick. Thicker ones tend to be softer, meaning they also sleep warmer because your body sinks deeper beneath the surface. Toppers with ventilated core materials also promote better airflow than those with solid layers.
  • Breathable, cooling foams: Memory foam toppers tend to sleep the warmest, but foams infused with gel beads, copper, and other cooling materials resist heat build-up fairly well.

Avoid:

  • Thick, dense foams: A softer memory foam topper will likely feel too warm if you are a hot sleeper. The material retains body heat to a noticeable extent. Down alternative – a polyester material that mimics the softness of real down – can also be a heat trap for some.
