Research suggests that the ideal temperature for sleeping is around 65 degrees Fahrenheit. While there are many factors that contribute to the temperature of your sleep environment, the importance of your mattress shouldn’t be underestimated. Mattresses that don’t allow room for airflow can trap body heat and lead to an uncomfortably warm night.

If you believe that your mattress could be the culprit for your sleepless nights but you’re not prepared to invest in a new one, a cooling mattress topper may be the best solution. Cooling mattress toppers can be made of latex, wool, gel memory foam, or other materials that draw heat away from the sleeper. They are usually 2 to 4 inches thick and designed to lie on top of your mattress, providing a cooler surface for your body to interact with.

We’ll cover everything you need to know about selecting the best cooling mattress topper, including our top picks and recommendations on choosing a mattress topper based on material, body type, preferred sleep position, and more.

Many memory foam toppers absorb and trap heat, causing them to feel uncomfortably warm for sleepers. The Saatva Graphite Mattress Topper manages to sleep cooler than most competitors thanks to its construction. The top layer is composed of memory foam infused with graphite, which has natural cooling properties. This material is intended to draw heat away from your body and keep the surface relatively cool. A 2-inch base layer of high-density polyfoam reinforces the topper to prevent deep sinkage while you sleep.

The firmness level is medium soft (4), so you should expect close contouring from head to toe. Those who find their current mattress too firm should notice comfort improvements. The 3-inch profile also makes this topper a good option for people with older mattresses that have become uneven over time. A breathable organic cotton cover enhances the topper’s cooling properties by promoting airflow. The cover is equipped with thick elastic bands to secure the topper to your mattress, so it shouldn’t shift too much even if you toss and turn or frequently change sleep positions.

Saatva ships the Graphite Mattress Topper free of charge throughout the contiguous U.S. Each order includes a 180-night sleep trial, giving customers plenty of time to test out their topper and decide whether to return it or keep it. Those who opt for the latter also receive a 1-year manufacturer’s warranty.

Finding a mattress topper that’s both high-quality and affordable can be challenging, but the Gel Swirl Memory Foam Topper from Brooklyn Bedding nicely tows the line between affordability and performance. The topper is composed of plush, adaptive memory foam that responds slowly to the body and contours closely for optimal pain and pressure relief. Our testers liken the feel of this topper to lying on a cloud and two profiles are available depending on how uneven your mattress feels, yet the sticker price falls well below average compared to competing memory foam models.

A cooling gel infusion helps combat heat retention and help you stay cool. The foam also has a lower density, so air circulates more freely throughout the material. The 3-inch topper has a medium soft (4) feel that is ideal for many side and back sleepers weighing less than 130 pounds. This firmness is best suited to people who own mattresses with heavy wear and tear. The 2-inch topper is medium (5), so it contours less closely and is a better fit for slightly used mattresses with at least a couple more years left. Side and back sleepers weighing up to 230 pounds may also prefer this option.

The topper does not come with a cover and the foam should only be spot cleaned as needed, so you may want to invest in a protector to safeguard it against stains and other types of damage. Brooklyn Bedding offers free ground shipping throughout the contiguous U.S. The company allows returns within 30 days of delivery, and each topper is further backed by a 3-year warranty.

  • Two firmness options
  • GOLS-certified organic Dunlop latex offers gentle contouring for pressure points
Sleep Foundation Exclusive Offer!

Use this SleepFoundation.org link for the most current discount on Silk & Snow mattress toppers

The Silk & Snow Organic Mattress Topper is a highly comfortable topper with a Dunlop latex core, which offers gentle contouring to relieve pressure points without excessive sinkage. Latex is a naturally breathable material that does not retain as much heat as adaptive foams, making it a great choice for hot sleepers. Global Organic Textile Standard and Global Organic Latex Standard certifications ensure the topper’s core and cover materials are grown sustainably and processed with ecological and social criteria in mind.

A cover made from organic cotton is naturally breathable. This cover is fully removable and machine-washable for easy care, but the latex core should only be spot cleaned. The topper’s 2-inch profile is suitable for people seeking to correct the feel of a mattress with slight indentations.

Two firmness levels are available: medium (5) and firm (7). Back sleepers on our team enjoyed the medium feel, which alleviates pressure in the lower back without uncomfortable sagging. Side sleepers over 230 pounds may also appreciate the softer feel to reduce pressure buildup in the joints. Back sleepers over 230 pounds and stomach sleepers appreciated the firmer option that kept their bodies on an even plane.

Customers living in the contiguous U.S. and provincial Canada are eligible for free shipping. Silk & Snow offers a 100-night sleep trial, during which you can return a topper for a full refund. The Organic Mattress Topper is backed by two warranties: 3 years for the latex core and 1 year for the cotton cover.

Who it's best for:

  • Exceptional temperature control thanks to breathable, moisture-wicking components
  • Topper holds GOTS, Wool Integrity NZ, and Forest Stewardship Council certifications
Sleep Foundation Exclusive Offer!

If your current mattress sleeps too hot, then a topper that promotes airflow may be a wise investment. The Birch Organic Mattress Topper is constructed with breathable components, including a top layer of natural wool over a base of Talalay latex. The wool has moisture-wicking properties to help you stay dry at night, while the latex is ventilated to push air close to the surface. A cooling cover made of organic cotton completes the design.

The topper has a medium (5) feel, making it a good option for mattresses that feel overly firm, but the latex cushions the body without the deep hugging sensation of memory foam. Latex is also somewhat responsive, resulting in a light bounce when you get in and out of bed. We recommend this topper for mattresses with light to moderate wear and tear.

The topper should also appeal to consumers who prefer to buy and use eco-friendly goods. A certification from the Forest Stewardship Council ensures the rubber trees used to produce the latex are sustainably grown and harvested, while a Global Organic Textile Standard certification indicates the same environmentally friendly practices for the cotton. Animal-conscious individuals should also appreciate the Wool Integrity NZ certification, which recognizes humane animal treatment during every stage of the wool extraction process.

Birch offers free ground shipping to all 50 states. Each order comes with a 100-night sleep trial, giving you plenty of time to test out the Organic Mattress Topper and decide whether it’s right for you. Those who decide to keep it also receive a 10-year warranty against structural defects.

Shoppers who want to enhance their mattress’ performance with a higher-profile topper will appreciate the Active Cooling Copper Topper from ViscoSoft. With its competitive price-point, this topper is also a good pick for shoppers on a budget. The topper features two copper-infused foam layers, one made from polyfoam and the other from memory foam. Together, these layers provide a combination of support and pressure relief suitable for sleepers who weigh up to 230 pounds.

The Active Cooling Copper Topper has a 4-inch high profile, so sleepers are likely to feel the hugging sensation that memory foam is known for. The fabric cover is infused with fibers containing phase change material designed to sleep cool. The cover is fully machine washable, and elastic straps keep it securely fastened to your mattress.

Side and back sleepers might enjoy this topper the most since it may not provide enough support for people who sleep on their stomachs. Side sleepers often feel pressure points under their hips and shoulders, which this topper is engineered to relieve. All-foam mattresses and toppers can often sleep hot, but the topper uses copper-infused foam designed to mitigate this issue. These types of foams are engineered to help regulate temperature by drawing body heat away from your mattress and releasing it.

ViscoSoft ships the Active Cooling Copper Topper free to the contiguous U.S. Shoppers have 60 nights to try their topper, and it’s backed by a 5-year warranty against structural defects.

Many cooling mattress toppers regulate temperature through passive cooling, which means they are made from breathable, moisture-wicking materials that dissipate body heat and maintain a comfortable sleep surface. The innovative Smart Topper from Perfectly Snug is a bit different because it provides active cooling. The topper is designed for dual settings, so both you and your partner can program your side of the bed for a specific temperature without affecting the other person.

The topper is constructed with a power cord you plug into a wall outlet, fans located at the foot of the bed, and channels that allow air to circulate throughout the interior. Simply flip on the switch and set your desired temperature using the Perfectly Snug Controller smartphone app. You can opt for heating on chilly nights or if you naturally sleep cool. Likewise, cooling is available for hot sleepers and warm or humid climates. The cover is ventilated for extra breathability.

In addition to its cutting-edge temperature controls, the Smart Topper is also quite comfortable. The core consists of solid memory foam with a balanced medium feel, which creates a surface that’s both invitingly plush and supportive for people who weigh up to 230 pounds. Its 2-inch profile ensures a noticeable comfort adjustment without drastically changing the feel of your mattress. Twin and twin XL sizes are available for single sleepers, while couples can opt for a queen, king, split king, or California king topper.

The Smart Topper’s high price-point will be too expensive for some shoppers, but this may be a valuable investment for couples who constantly contend with sleep temperature issues. Your purchase comes with a 30-night sleep trial, during which you may return the topper in reasonably used condition for a full refund. Those who keep the topper will also receive a one-year warranty.

Sleep Foundation Exclusive Offer!

Use this SleepFoundation.org link for the most current discount on PlushBeds mattress toppers

Firmness preferences differ from person to person, so a topper sold in multiple firmness levels naturally accommodates more sleepers. With the PlushBeds Latex Mattress Topper, customers can choose from five different firmness options. Those who weigh less than 130 pounds and find their mattress too firm will likely prefer the soft or medium soft feels. Conversely, sleepers who weigh more than 230 pounds and sink too deeply into their mattress will probably feel more comfortable with a medium firm or extra-firm topper instead. The medium feel is a solid choice for those who weigh 130 to 230 pounds and prefer moderate contouring.

Additionally, the topper is available in 2- or 3-inch profiles. The former is best suited to people who want to slightly adjust the comfort level of their mattress, whereas the latter will significantly change how the mattress feels. All versions of the topper are constructed using natural latex, which is both durable and responsive. The latex is ventilated with small holes to promote air circulation and prevent overheating. The latex should only be spot-cleaned, but PlushBeds offers an optional, machine-washable cover made of organic cotton to protect the topper. The fabric is highly breathable and won’t inhibit airflow, so the topper should sleep reasonably cool whether you use the topper or not.

The cost of this topper depends on the selected size and profile. Although the sticker price might seem high, the latex offers excellent longevity and – if properly cared for – could perform for several years before a replacement is needed. PlushBeds also offers free ground shipping throughout the contiguous U.S. Returns are not accepted, but each topper is backed by a 5-year warranty.

Tempur-Pedic TEMPUR-Adapt Topper

Best for Back Pain

Tempur-Pedic TEMPUR-Adapt Topper

Tempur-Pedic TEMPUR-Adapt Topper
Price: $419
Firmness: Medium (5)
Who it's best for:
  • Those wishing to improve their current mattress’ motion isolation
  • Side and back sleepers
  • Shoppers willing to spend a bit more for high-quality materials
Highlights:
  • Three inches of memory foam provide ample cushioning
  • Above-average durability
  • Removable and washable cover
Sleep Foundation Exclusive Offer!

Use this SleepFoundation.org link for the most current discount on Tempur-Pedic mattress toppers

The TEMPUR-Adapt Topper from Tempur-Pedic is an excellent choice for sleepers looking to enhance their current mattress’ comfort. This memory foam topper has a medium feel that easily compresses beneath high-impact areas like hips and shoulders, helping to cushion pressure points. The topper has an above-average price-point, but Tempur-Pedic’s products are well-known for their durability and this model should have a lengthy lifespan.

Adding this topper to your current mattress can also help enhance its motion isolation. When you shift sleeping positions on a highly responsive mattress, the movement your body generates can transfer across the surface. TEMPUR memory foam traps most motion, which lets couples move on their side of the bed without disturbing their partner.

The topper is 3 inches thick to provide substantial contouring and pressure relief. Hot sleepers may find this model retains some body heat, but it shouldn’t greatly affect your mattress’ overall temperature regulation.

The topper itself should not be machine-washed or dry cleaned, but each purchase includes a removable and washable cover that protects the foam. The TEMPUR-Adapt Topper carries a 10-year warranty and ships free to addresses within the contiguous U.S.

Puffy Mattress Topper

Best for Side Sleepers

Puffy Mattress Topper

Who it's best for:
  • Active sleepers or those who change positions frequently
  • Individuals with sensitive pressure points
  • People who own mattresses up to 15 inches thick
Highlights:
  • Available in two different firmness options
  • Grip on the bottom keeps the topper from shifting

Sleep Foundation Exclusive Offer!

Use this SleepFoundation.org link for the most current discount on Puffy mattress toppers

The Puffy Mattress Topper has a soft all-foam construction that closely contours to the body to relieve pressure buildup in the shoulders, hips, and lower back. Thanks to the adaptive feel, we recommend the topper for side sleepers.

Shoppers can choose between two different firmness levels, which are soft or firm. Both versions, however, are made using layers of memory foam that evenly distribute body weight. To help prevent overheating, the 2.5-inch topper comes encased in a cooling cover made of polyester and rayon from bamboo. The cover can be removed and machine washed.

The topper features a thin anti-slip grip on the bottom to prevent the topper from shifting along the surface of your mattress. This grip works with elastic corners, which can stretch up to 15 inches, to keep the topper in place. The topper is available in all six standard mattress sizes.

Puffy provides free shipping to customers in the contiguous United States. The Puffy Mattress Topper also comes with a 101-night sleep trial and a lifetime warranty.

Sleep Foundation Exclusive Offer!

Use this SleepFoundation.org link for the most current discount on Turmerry mattress toppers

The Turmerry Organic Latex Mattress Topper is a versatile topper that comes in three firmnesses and two profile options. The different firmness levels, coupled with the contouring properties of latex, make this an excellent topper for sleepers of all different body types and sleeping positions.

The topper is composed of 100% Dunlop latex, which conforms moderately to the body but is also plenty supportive. Shoppers can pick from a 2-inch or 3-inch topper as well as a soft (3), medium (5), and medium firm (6) feel. The thicker topper will adjust the feel of your bed surface more significantly than the thinner model, making it a great option if you own an old or indented. The soft and medium options should appeal to side and back sleepers who seek pressure relief in the shoulders, hips, and spine, while the medium firm may appeal to stomach sleepers who need the added support to keep the midsection from sinking in. Stomach sleepers who weigh over 230 pounds may sink too deep to receive proper support.

The latex is encased in an organic cotton cover that is soft and breathable. Since latex is naturally breathable, sleepers should stay fairly cool on this topper. The latex also has certification from the Global Organic Latex Standard (GOLS) to ensure it meets strict standards for organic sourcing.

Turmerry offers free shipping to customers in the contiguous U.S. The topper includes a 60-night sleep trial as well as a 5-year warranty.

How to Choose a Cooling Mattress Topper


Sleeping cool has become a major buzzword in the mattress industry, and all the marketing jargon about the latest technologies and state-of-the-art materials can be overwhelming. This guide will help you to cut through the hype and help you find the best cooling mattress topper for you.

What to Consider When Purchasing a Cooling Mattress Topper

There are a lot of choices to sort through when buying a cooling mattress topper. From price to material, cooling properties to sleeping position, here are some of the most important factors you should keep in mind while you search.

  • Cooling Properties: The most straightforward way to maintain temperature neutrality is by using materials that allow for airflow, thus carrying the heat away from your body. Some mattress toppers accomplish this with the use of naturally breathable materials, like latex or open-cell foams and cotton or wool covers. Others feature a convoluted or aerated design that increases air circulation.For materials that are inherently prone to retaining heat, manufacturers must resort to other tactics. These include charcoal, graphite, gel, or copper infusions designed to transport heat away from the body. Some mattress toppers incorporate phase-change materials, which regulate temperature by absorbing, storing, and releasing heat.For people who run very hot at night, it might be worth investing in a topper that allows you to control the temperature at the touch of a button. These active cooling toppers work by heating or cooling air or water and pushing it through the mattress to actively control the surface temperature.A few mattress manufacturers make toppers that are cooler in certain areas, such as the core. This can have the added advantage of alleviating aches and pains.
  • Price: The price of a mattress topper can vary widely depending on materials and quality. Cooling polyfoam mattress toppers start at less than $100, but you can expect to pay several hundred dollars for a latex topper, and even more for sophisticated devices with cooling tubes. That said, if the added price means better longevity or reduced air conditioning bills, it might pay off in the long run.
  • Sleeping Position: Since your mattress topper goes on top of your mattress, it’s important to choose a topper with the right firmness to accommodate your body type and sleeping position. Side sleepers usually opt for a plusher surface that reduces pressure points, so they may need a thicker topper to form a cradle for the hips and shoulders. Stomach sleepers should be fine with a firmer, thinner topper, while back sleepers fall in the middle of the spectrum.
  • Quality Materials: Latex and wool toppers offer the best longevity, and you can expect them to last around 3 to 4 years on average.In contrast, a low-quality memory foam topper can develop permanent body indentations before the year is out. Higher-density polyfoam or memory foam toppers will last longer than their lower-density equivalents, but they will also usually trap more heat. Fiberfill and feather toppers are fairly high-maintenance and require regular fluffing in order not to lose loft over time. You can usually expect these to last around 2 to 3 years.
  • Firmness Level: Since a mattress topper can’t add support to a sagging mattress, the main reason people purchase mattress toppers is to adjust the firmness level of a mattress. In general, lighter sleepers and side sleepers are best suited to a plusher topper, while stomach sleepers and heavier individuals are best suited to a firmer topper.Mattress firmness plays a crucial role in heat retention, as a softer surface allows the body to sink in further and causes more heat to build up around the sleeper. The heavier the sleeper, the more they will sink into the mattress, leading to increased heat retention. If you find you run hot, you may want to consider getting a firmer mattress topper.
  • Thickness: Mattress toppers tend to measure between 2 and 4 inches thick. People who exert more pressure on the mattress, such as heavier sleepers and side sleepers, should look for a thick mattress topper that can handle this extra weight without bottoming out.
  • Pressure Relief: Memory foam is usually acknowledged as the best material for pressure relief due to its close-conforming abilities. However, if you overheat with memory foam, a latex mattress topper may do the trick. Latex can have pressure-relieving properties similar to memory foam, but it’s more breathable and forms a looser cradle around your body.

Which Type of Mattress Topper is Best at Cooling?

Most toppers on the market today are made of memory foam, polyfoam, or latex, each of which offers its own advantages. You may also see mattress toppers stuffed with wool, which wicks moisture away from the body to keep you cool when it’s hot and warm when it’s cold.

  • Memory foam: Memory foam is a popular material for mattress toppers because it offers superior pressure relief and motion isolation. Unfortunately, memory foams, particularly high-density memory foams, have traditionally been known for trapping heat. Modern-day cooling memory foam mattress toppers get around this by infusing the memory foam with charcoal, copper, graphite, or other substances that draw heat away from the sleeper.
  • Polyfoam: Open-cell and convoluted polyfoam mattress toppers are designed to improve airflow, allowing body heat to escape from the sleeper instead of building up on the surface of the mattress. Polyfoam has the added advantage of being the cheapest topper material. The downside is that polyfoam toppers will eventually develop permanent body indentations.
  • Latex: Natural latex is a breathable, open-cell material that is prized for its durability and sustainability. Latex tends to keep sleepers “on” and not “in” the mattress, preventing heat build-up around the body. While natural latex toppers can be expensive, they maintain decent temperature neutrality and are much less likely to develop body indentations compared with synthetic latex or other foams. Many latex toppers are “ventilated” with pincore holes that allow for better air circulation.
  • Gel: Many manufacturers use gel infusions, gel beads, or a top layer of gel in an effort to stem heat retention in memory foam or fiberfill toppers. As we will discuss in the next section, the jury is out on whether or not this is actually an effective cooling technique.

Frequently Asked Questions About Cooling Mattress Toppers

  • Do gel mattress toppers keep you cool?

    While they may help a memory foam topper sleep somewhat cooler at first, cooling gel mattress toppers don’t always manage to keep a neutral temperature all night long. The gel may also lose potency over the years.There are two principal ways by which gel is used to help memory foam sleep cooler. Thermal gels are cool to the touch, whereas phase-change gels regulate heat by absorbing and redistributing it to maintain a constant temperature.

    While these techniques can stave off heat retention for a while, many sleepers find that the mattress eventually warms up anyway. However, a cool gel memory foam mattress topper may help keep the temperature low long enough to help you drift off to sleep.

    In a nutshell, if you sleep hot but have your heart set on memory foam, then a gel memory foam topper might be the way to go. But for people who sleep very hot, it’s usually better to avoid memory foam altogether.

  • Do cooling mattress toppers really work?

    Cooling mattress toppers have varying degrees of success depending on the type. Materials like latex, wool, and open-cell or aerated foams can help disperse heat, but they won’t actively cool the mattress.

    Phase-change material goes an extra step by using a chemical reaction to keep the surface cool to the touch. For people who are very sensitive to temperature changes, the best solution might be a mattress topper that actively works to control the temperature via water or air channels.

  • What’s the difference between a mattress pad and a mattress topper?

    Mattress pads are relatively thin and are primarily meant to protect against spills and stains, whereas mattress toppers are usually several inches thick and are designed to change the feel of a mattress.Mattress pads often contain some kind of padding like wool, cotton, fiberfill, or down. While this can add some plushness to a mattress, this is not their main purpose.

    Mattress toppers usually come in the same materials you would expect from a mattress comfort layer, such as memory foam, polyfoam, latex, wool, or down. A mattress topper can’t fix an old, sagging mattress, but it can change the feel of a mattress that’s too firm or too plush. This is a cost-effective way to obtain a different firmness level without investing in a whole new mattress.

  • Can I buy sheets to keep me cool?

    The sheets you use definitely play a role in maintaining temperature neutrality. Linen, cotton, and bamboo are all naturally breathable and will help fight heat retention. In terms of weave, stay away from flannel sheets and choose sheets with a breathable percale weave. Some synthetic fabrics also use technology such as phase-change material to keep you cool.

    It’s important to remember that the temperature of your sleeping environment is a product of many factors including your mattress and/or topper, sheets, ambient temperature, your pillow, and your own personal body heat.
