Memory foam mattresses continue to be a popular choice for people shopping for a new mattress due to the benefits of sleeping on one. Not only can memory foam help reduce aches and pains with support and pressure relief, but it also helps sleepers toss and turn less. Overall, the benefits of a memory foam mattress can help contribute to a better night of sleep.
Even though memory foam mattresses can improve your quality of sleep, one downside that many sleepers struggle with is overheating in the middle of the night. Memory foam responds to your body heat to cradle your body more effectively, but it also retains that heat. If you are a hot sleeper, a memory foam mattress might not feel like your coolest option.
With the popularity of memory foam means that there are more options, which includes memory foam with cooling properties. We’ve put together an in-depth mattress review to help you find the best mattress for hot sleepers so that you can enjoy the benefits of memory foam without worrying about overheating.

Our favorite memory foam mattress for hot sleepers is the Amerisleep AS3. We like the AS3 because it has a true medium firmness, so it offers an even balance of comfort and support and is comfortable for the majority of sleepers. While memory foam mattresses are known for sleeping hot, Amerisleep mitigates this concern by using plant-based, porous foams in their beds instead of denser traditional foams. Plus, they use a soft, breathable cover to promote air circulation throughout the mattress.
The top layer of the AS3 is 3 inches of Bio-Pur®, Amerisleep’s plant-based memory foam. Bio-Pur® has an advanced open-cell structure, leaving more room for air to flow in and out of the mattress; as a result, Bio-Pur® is five times more breathable than traditional memory foam. Plus, because this foam is plant-based, it shouldn’t off-gas like other memory foam beds— helping you sleep clean, cool, and comfortably.
Below the layer of Bio-Pur® is this bed’s zoned support layer featuring HIVE® technology. While HIVE® is in place primarily to support healthy sleeping positions, its design improves the bed’s airflow. HIVE® is made with hundreds of hexagonal cutouts, and the spaces between these cutouts make it easier for hot air to escape out of the mattress.
Amerisleep offers a 100-night sleep trial with each of their beds, so you can buy it and determine if it’s the solution to your hot nights. If you decide the mattress is right for you, it’s backed by Amerisleep’s 20-year warranty.
Next on our list is the Zoma Sports Mattress, a memory foam mattress designed for athletes. We like the Zoma mattress because it’s equipped with cooling gels and a breathable support technology to regulate your temperature. The Zoma Sports Mattress is built to for medium firmness, but many reviews of it say it feels softer rather than firmer. We recommend the Zoma to back and side sleepers, but it’s too soft to support stomach sleeping.
The Zoma Sports Mattress is covered with a stretchy, breathable polyester to keep hot air moving out of the mattress, rather than trapped within.
The first layer of Zoma is 2 inches of gel memory foam. When you lay on this bed, the memory foam contours to your body while the gels within dissipate body heat out of the mattress and provide a cooling sensation. Zoma includes its Triangulex™ support technology within this layer, too. Triangulex™ is designed with triangle-shaped cutouts to provide dynamic support under your midsection, shoulders, and hips. The gaps between these cutouts serve as cooling channels in the bed to keep hot air flowing out of the mattress.
These two features within the top layer work in tandem to keep you feeling cool and prevent hot air from being trapped within the mattress. Zoma is an online-only mattress brand, so you can order online and try the bed at home. Zoma offers a risk-free 100-night sleep trial, allowing you plenty of time to determine if the Zoma mattress is right for you. Zoma also backs each of their mattresses with a 10-year warranty.
3. The Muse Mattress
The Muse mattress is an all-foam mattress and available in three comfort levels: soft, medium, and firm. It’s also comprised of three foam layers, each one playing an important role in comfort, support, and keeping cool while sleeping. The 8-inch base layer is a dense memory foam that supports your body while the 2-inch responsive comfort foam is your “comfort level layer.” The 2-inch gel-infused memory foam layer keeps you sleeping cool all night long.
Nearly all memory foam mattress brands focus on a design with pressure relief and lower back support, but few have a whole layer dedicated to regulating body temperatures. Not only does the Muse mattress have excellent motion isolation to reduce movement while you sleep, but the mattress also has good edge support to help avoid that “sinking” feeling that comes with some memory foam mattresses.
In addition to the cooling gel layer, which benefits hot sleepers, the Diamond Breeze washable cover has a breathable design to increase air circulation instead of trapping heat.
The memory foam mattress is protected by a 10-year warranty that covers defects that don’t originate from regular “wear and tear.” Defects under warranty include excessive sagging, deterioration of the mattress, cracking or splitting of the foam, or fabric tears due to manufacturing defects. Improper maintenance of your mattress will void the warranty. Muse also offers a 120-day sleep trial, which means that from the day of delivery, you have 120 nights to test out the mattress and see if it keeps you cool and comfortable.
4. Zinus Cooling Memory Foam Mattress
Most memory foam mattresses only offer a few thickness options, but the Zinus memory foam mattress is available in four thickness options: 8, 10, 12, or 14-inches. The 8-inch mattress is medium-firm, and the firmness level increases with each thickness level. Regardless of the thickness of the mattress, each one contains a layer of swirl foam, a comfort layer, and high-density foam.
In addition to the cooling gel foam, which is designed to keep the mattress cool and comfortable during warm weather, the foam also contains green tea for neutralizing odor. The Zinus mattress is a CertiPUR-US® foam mattress with a breathable “cool” fabric washable cover that helps regulate body temperature and prevents waking up in the night due to overheating. Although the Zinus memory foam mattress has a comfortable and supportive design, the Cooling Memory Foam Mattress is designed with hot sleepers in mind.
Zinus offers a Worry-Free limited 10-year warranty, which covers manufacturer’s defects. Using the wrong platform or not properly maintaining the memory foam mattress can void the warranty. The company also offers a 100-night sleep trial, which begins on the date of delivery. If you don’t like the mattress, you can return for a full refund as long as you have proof of purchase, and there is no damage to the mattress, such as odors or spills.
5. Bear Mattress
Bear makes a few other types of mattresses, including a hybrid mattress, but the original Bear is a cooling mattress for hot sleepers that focuses on temperature regulation and comfort. The 10” mattress contains not only memory foam, but also responsive polyfoam, adaptive polyfoam, and high-density support foam. The mattress cover is poly and celliant fabric cover, which has cooling technology and prevents heat retention from building up on the cover.
The memory foam is infused with graphite cooling gel to reduce the chance of waking up in the middle of the night due to overheating. The mixed foam also provides adequate support and pressure relief to all types of sleepers while the motion transfer reduces tossing and turning. The medium-firm mattress comfortably cradles most sleepers without making them feel trapped in one position.
The Bear memory foam mattress comes with a 10-year warranty, which covers manufacturer’s defects such as indentations that are more than one-inch, cracking, or splitting of the mattress. Things that may void the warranty includes improper care, exceeding the weight recommendation, and not using the right type of mattress base.
Bear also offers a 100-night sleep trial, which lets you test out the mattress risk-free. Bear recommends that users try the mattress for at least one month before returning for a refund.
6. Modway Aveline
The Aveline memory foam mattress by Modway is a medium to medium-firm mattress available in three thickness options: 6, 8, or 10-inches. The three-layer mattress is designed for comfortable support and to help hot sleepers stay cooler all through the night.
The top layer of the Aveline includes a breathable fabric cover that helps promote airflow and prevents trapping heat in the other layers of the foam mattress. The second layer contains cooling gel memory foam, which prevents the mattress from retaining heat while you sleep and reduces the chance of you waking up due to overheating.
The third layer is a high-density responsive foam that not only offers pressure relief but has excellent motion transfer. Motion transfer helps to reduce restlessness and waking because your partner is tossing and turning.
Not only is the Aveline budget-friendly memory foam mattress with cooling features, but it also has sufficient support layer through the mattress to prevent rolling or sagging.
Modway offers a limited 10-year warranty on the Aveline, which covers manufacturer’s defects like excessive sagging, cracking, or splitting. Normal use does not typically affect the validity of the warranty, but Modway strongly recommends following all care and maintenance instructions carefully to avoid warranty issues.
You can test out the Aveline for 100 nights from the date of delivery. While the 100-night sleep trial is slightly shorter than competitors, it generally gives you enough time to decide if it’s the best cooling memory foam mattress for hot sleepers.
If you think about your sleep position, you’ve probably slept in the same position since childhood. While many people try out different positions before drifting off to sleep, you’re likely to have a “tried and true” sleeping position that is most comfortable and effective of helping you fall asleep.
Many factors play a role in restless sleep. While your mattress is essential to good sleep, your sleep position is equally important. Here’s a closer look at the most common sleeping positions, some of the benefits of each, and how they come into play as a hot sleeper and memory foam mattresses.
If you’re a side sleeper, you are part of the majority. More than half of all sleepers prefer sleeping on their sides. The two main side sleeping positions include “The Log” of “The Fetal Position.” Even though both are side sleeping positions, they are quite different in how you position your body.
The log position is similar to what it sounds like because you keep your body straight, and your arms are either at your side, in front of you, or tucked underneath your pillow. To some, this position may look uncomfortable, but it’s an excellent position for keeping your spine aligned and promotes comfortable sleep. When you sleep on your right side, there’s less pressure on your heart while you sleep, which means your blood pressure is more likely to stay normal.
When you think of the fetal position, you might imagine someone curled up in a ball on their side. This is a natural and comfortable position for over 40 percent of side sleepers, but curling up your body too tightly can result in breathing issues and back strain. If you’re a hot sleeper, this position doesn’t allow your body to get enough airflow, so you’re likely to wake up sweaty.
If you sleep warmer than most and like sleeping in the fetal position, try to train yourself to loosen up. While you may never stretch out enough into a log position, “uncurling” your position can allow for better airflow.
Memory foam mattresses are an excellent choice for side sleepers because the foam provides support in areas that need it, like the hips. They also have pressure relief in areas like the shoulders or knees. A medium to medium-firm memory foam mattress helps to reduce the feeling of “sinking” into the foam. As a side sleeper, you may find memory foam mattresses with solid side support more comfortable.
As a hot sleeper who sleeps on your side, cooling memory foam can help you stay on one side. You are less likely to wake up due to trapped heat under your body.
If you’re a back sleeper, you probably either sleep with your legs straight and your arms to your side or a bit more in the “free fall” position with relaxed arms and legs. If you suffer from tension headaches or congestion, sleeping on your back can help reduce these issues. Sleeping on your back can help keep your spine in alignment, and a medium to medium-firm memory foam mattress helps with back issues.
Aside from the numerous benefits related to sleeping on your back, it may become your favorite position as a hot sleeper. Even though your back may get warm when you sleep on your back, the rest of your body can have better airflow. A memory foam mattress with cooling properties will keep your backside cool and supported.
Stomach sleepers often sleep in a fetal position or the “free falling” version of sleeping on your stomach. There aren’t many health benefits to sleeping on your stomach, even if it’s a comfortable way to sleep. As someone who sleeps hot, you’re likely to trap heat under your body, and the strain of sleeping on your stomach can lead to a restless night.
One good thing about stomach sleeping is that it helps reduce snoring. However, the back and neck pain, heat retention, and other issues may not be worth sleeping in this position. A memory foam mattress with cooling gel can reduce the build-up of heat. If you can’t fall asleep without sleeping on your stomach, make sure to choose a memory foam mattress that is soft enough to support your ribs and stomach but firm enough to align your spine.
Check out some of these frequently asked questions that many people ask when looking for the best cooling memory foam mattress for hot sleepers.
Can Sleeping Too Hot Make You Sick?
If you are a hot sleeper, it can affect your circadian clock, or body clock. Disruptive sleep can weaken your immune system and cause other health problems. Fortunately, there are ways to reduce overheating while you sleep, including sleeping on a cooling memory foam mattress.
What is Cooling Memory Foam?
Cooling memory foam typically contains a layer of cooling gel, or the gel beads are integrated into the foam. Today, you are likely to find more cooling memory foam mattresses that use other “cooling” materials like graphite, copper, and other natural ingredients.
Cooling memory foam has the same benefits of traditional memory foam, like a relief for pressure points and back support, but reduces heat retention.
How Does Cooling Memory Foam Work?
Cooling memory foam is designed to draw heat away from the body and reduce heat retention in the mattress. Although cooling foam does a better job at keeping sleepers cool and comfortable than traditional memory foam, it still warms up a bit.
Hot sleepers may benefit from gel cooled open-cell memory foam that has a separate cooling layer rather than foam that is mixed with cooling materials.
Is Cooling Memory Foam Safe?
There’s a lot of mixed information when it comes to the safety of memory foam or foam containing cooling properties. While many chemicals go into making memory foam mattresses, there’s not enough evidence to prove whether or not cooling memory foam is safe for you.
Some individuals with sensitive respiratory systems have a hard time with the “off-gassing” period of a foam mattress. Whether you purchase a mattress with organic materials or a traditional memory foam mattress, you will experience a bit of odor that typically disappears after a few days.
What’s the Best Firmness Level for a Cooling Memory Foam Mattress?
Memory foam mattresses typically come in a variety of firmness levels and thicknesses. The less “give” that a foam mattress has, the less likely you are to trap heat under your body. Ideally, if you are a hot sleeper, you may benefit from a firmer memory foam cooling mattress than one that’s plush or softer.
Keep in mind that there are other factors to consider, such as body weight and sleeping position, when determining your best mattress. If you require a mattress with higher weight capacity, a firmer mattress is a better option when it comes to the longevity of your mattress.
How Do You Cool Down a Memory Foam Mattress?
Memory foam mattress with cooling properties can help improve your sleep if your a hot sleeper, but it might not be enough to keep you cool. Consider breathable sheets that wick away moisture and doing other things to keep your room cooler, like turning down your heat.
Keep in mind that simply purchasing a memory foam mattress with cooling gels may not be enough to prevent night sweats.
Does Memory Foam Make You Hot?
If you’re always waking up in a pool of sweat, your mattress may be to blame. There are other factors as to why you’re a warm sleeper like hormonal changes, sleeping with a partner, or wearing warm pajamas. Body temperature fluctuation is normal during sleep, but it can also disrupt your quality of sleep.
Memory foam often has a bad reputation for retaining too much body heat, but if you buy a memory foam mattress with cooling properties, like gel, copper, or graphite, you’re less likely to feel overheated at night.
Do Cooling Mattresses Work?
With so many cooling mattresses on the market, you might be wondering how effective they are at keeping you cool while you sleep. The best way to see if a cooling mattress is the best choice for you is to find a manufacturer that includes a sleep trial.
Many mattress companies offer a risk-free sleep trial that lasts a few months, which is typically enough time to determine if the mattress is right for you. Before you purchase a mattress, make sure you understand the details of the sleep trial.
How Can I Stop Myself From Overheating at Night?
It’s normal for your temperature to fluctuate while you sleep, but if you’re a sleeper who already “runs hot,” you’re familiar with waking up sweaty every night. A cooling memory foam mattress can greatly reduce your likelihood of night sweats, but there are other things you can try to keep from overheating.
Avoiding exercise before bed, wearing lightweight breathable pajamas, and keeping your room cool can all help. If you try all these things and also sleep on a cool memory foam bed but still overheat, consider making an appointment with your doctor to make sure you have no health issues causing you to overheat.
What is the Best Bedding for Night Sweats?
Even if you sleep on a cool mattress, it’s a good idea to invest in a bedding that will help you stay cool and dry while you sleep. Satin and microfiber sheets are comfortable and stylish but don’t do a great job of wicking away moisture. Natural fabrics like cotton are popular choices among hot sleepers.
Can Memory Foam Cause Night Sweats?
If you sleep on a traditional memory foam mattress, there’s a good chance that it causes you to sweat in the middle of the night. Some people sweat in their sleep for several reasons, so your memory foam mattress may contribute to the issue but not the sole reason for night sweats.
Can You Clean Cooling Memory Foam Mattresses?
Like most mattresses, your options for cleaning your mattress are limited. Many cooling memory foam mattresses come with a breathable fabric cover. While some covers are removable and washable, other fabric covers are permanently attached and require spot cleaning. If you want a cover you can remove, make sure that your foam mattress offers the option.
What Type of Things Void A Mattress Warranty?
As you shop around for a cooling memory foam mattress, you may notice that most have a 10-year warranty. Most warranties cover manufacturer’s defects like splitting, cracking or sagging over one-inch. Before you decide on a mattress, make sure you understand the warranty.
All warranties differ, but some things that may void a warranty before it expires include spills, stains, and damage resulting from improper installation or care. The best way to ensure the warranty is valid is to follow the care instructions.
How Long Do Cooling Foam Mattresses Last?
High-quality foam mattresses typically last around ten years or longer. Thicker foam is likely to last a bit longer, and budget-friendly or softer mattresses will probably wear out faster. Other factors that affect the lifespan of your foam mattress includes weight capacity, mattress foundation, and how you care for your mattress.
As a hot sleeper, regularly waking up in the middle of the night drenched in sweat can be frustrating, tiring, and even detrimental to your health. There are plenty of things you can do to experience cooler sleep, such as adjusting the room temperature or buying a cooling mattress topper. Many sleepers find relief with a cooling memory foam mattress.
Finding the best cooling mattress might not happen right away. Since buying a mattress is a big investment and an important decision, don’t hesitate to take your time. You want to make a confident decision on whether or not the mattress is comfortable and has all the benefits you want.
Taking advantage of sleep trials is an excellent way to see how a mattress feels. During this period, you can also see if cools you while you sleep and provides adequate support and pressure relief. No one wants to spend time testing one mattress after another.
However, doing your research and knowing what you want will save you money in the long run and eliminate sleepless nights.
Although all cooling mattresses have a similar purpose and design, look for the best mattress that feels comfortable in your favorite sleeping position. The mattress should also meet your other sleep needs, not just keeping you cool.
