Sleeping hot is an issue that affects a lot of people, and it can really disrupt your normal sleep schedule. Waking up sweaty is an uncomfortable feeling, and trying to fall asleep when you’re too hot can feel impossible. It’s actually proven that body temperature and room temperature can throw off your circadian rhythm if they’re too high.
Finding a mattress that can keep you cool will not only be more comfortable, but it can also help give you a restful night’s sleep. There is a great deal to consider when it comes to the temperature regulation of your mattress. Your body type affects mattress choice, and certain materials are more likely to keep you cool than others. This mattress comparison will give you an in-depth look at the best cooling mattresses.
The Best Mattresses for Hot Sleepers: Our Top Picks

Special Considerations for Hot Sleepers
Depending on the materials used, the mattress type, and even the sleeper’s physical attributes—certain beds are not the best choice for hot sleepers. To help give you a better understanding of these features, we’ve outlined some important details below.
Certain types of mattresses are more likely to trap heat than others. Traditional innerspring beds allow air to travel through the inside of the mattress, which helps to cool the sleeping surface. On the other end of the spectrum, all-foam mattresses—especially those with memory foam—have virtually no airflow and are known to trap body heat. Hybrid beds attempt to find the middle point between the two and are a popular option among hot sleepers. There are foam beds that can manage to be temperature neutral thanks to specially designed materials, like gel memory foam.
The outer layer of your bed is one of the most important features because you have direct contact with these materials while you sleep. Thinner covers tend to sleep cool, especially compared to thicker quilted covers. Thicker materials will interfere with air circulation. Quilted covers also tend to use thin foams for added comfort, but (depending on the material) this can make the surface more likely to trap heat. Specially designed materials like Celliant fibers and phase-changing covers are made to regulate body temperature and keep you cool throughout the night.
Many mattress types have some type of foam beneath their covers, which—depending on the type used—can lead to heat retention. Some bedding companies will use a gel-infused foam because the gel absorbs heat without radiating heat back toward the sleeper. Other types of cooler foams are open-cell memory foam, copper-infused, and graphite infused.
Today, beds come in a wide range of different firmness options, usually landing between very soft and very firm. Mattresses that are medium to very firm tend to sleep cooler than soft mattresses. The reason for this is that you sleep on top of the mattress instead of sinking in. The softer a mattress is, the more likely a sleeper is to be cradled by the bedding material, which will trap more body heat.
Directly related to the firmness of a mattress is the sleeper’s body weight. A lightweight sleeper can lay on a soft mattress without sinking too far in, and therefore won’t trap as much body heat. Heavier sleepers will sink deeper into mattresses and overheat easier. Heavier individuals will typically find that medium-firm and firm mattresses will sleep the coolest.
Couples will generally benefit from a cooler mattress because there is twice the amount of body heat. However, if one partner sleeps hot and the other sleeps cool, they may not agree on how temperature neutral they want their mattress. In some instances, climate control systems could work as these special beds and bases can control the climate on each side separately.
The Best Mattress Types for Hot Sleepers
|Type of Mattress||How it Sleeps|
|Coils||Coils are used for the support layer in innerspring and hybrid mattresses. Using a coil support core allows plenty of room for air circulation inside the bed, and airflow is crucial to temperature regulation.|
|Latex||All-natural latex foam is a great material for hot sleepers. On top of the benefits of being organic and naturally hypoallergenic, latex is naturally breathable—the foam and its perforated design allows for maximized airflow. Synthetic latex is also used in some mattresses, but it may not have the same natural breathability.|
|Gel Memory Foam||Gel is a cooling element, so infusing it into foam helps keep the material temperature neutral. The gel absorbs body heat without feeling warm to the touch, and the more gel used inside the foam, the cooler it will sleep.|
|Specialty Memory Foam||Regular memory foam traps heat, but is also very comfortable. To get the same comfort without the heat-trapping properties, manufacturers have developed specialty memory foams. Infusing materials like copper and graphite help whisk heat away from the sleeper.|
|Advanced Polyfoam||Similar to specialty memory foam, advanced polyfoam is specially designed by manufacturers to include the comfort of regular polyfoam without the heat retaining properties. Unfortunately, because of the material type, these still tend to sleep hotter than most materials.|
|Open-Cell Memory Foam||An alternate way manufacturers have tried to improve upon memory foam is with an open-cell design. This type of memory foam sleeps cooler because it allows more airflow, but still traps a noticeable amount of heat.|
|Regular Polyfoam||Polyfoam has a low-density structure and open-cell structure which helps make it cooler than memory foam. The material does not perform as well as other natural materials or specially designed materials, and high-density polyfoams (often found used for a base layer) have less airflow.|
|Regular Memory Foam||Memory foam is notorious for trapping heat. The material contours to the sleeper by responding to body heat and applied pressure. This design, combined with the conforming properties, makes it a relatively hot sleeping surface.|
Other Tips for Hot Sleepers
While your mattress plays a significant role in temperature regulation, other sleeping accessories can play a factor as well.
- Mattress Toppers: Mattress toppers are often used to give extra comfort to your bed. The extra inch or two of the pad can negatively affect airflow (depending on the material). Memory foam sleeps the hottest, so a memory foam mattress topper will retain the most heat. Wool and feather toppers are the coolest materials.
- Sheets: Bedsheets are important because different fabrics can change how you respond to the cool-to-the-touch materials featured in some mattresses. Natural fibers like cotton, linen, and silk are naturally breathable. Wool responds to the temperature of your room, which makes it suitable during all seasons. Synthetic fibers like polyester and rayon tend to sleep warmer.
- Pillows: You lose a lot of heat from your head, so the pillow you use has an impact on your sleep temperature. Memory foam pillows and synthetic materials like polyester will trap heat and can negatively impact your sleep if you already sleep hot. Natural fibers have more breathability and are some of the most popular pillow material options. Materials like buckwheat, down, and latex are the most temperature neutral pillow materials.
- Climate Control System: Some premium beds include a climate control system that can be used to regulate mattress temperature. These are particularly helpful for couples with different sleeping preferences. Climate control systems typically use air tubes to cool down each side of the bed, either through a unique mattress or via the base.
- Environment: There are always environmental changes you can do to keep yourself cooler at night. Fans can be used to improve airflow, and some sleepers might find the background noise helps them sleep. For the best night’s sleep, it is suggested you keep your room between 60-67 °F. The clothing you wear to bed can further insulate you or restrict airflow, so consider breathable materials. Having your bed on a bed frame is a great way to improve airflow, plus it’s better for the longevity of your mattress.
Temperature and Sleep
You probably know that the human body temperature is 98 degrees, but you might not know that our temperature fluctuates throughout the day. Your body temperature actually cools down overnight, eventually getting to its lowest point at 96.4 degrees. Over the course of the morning, it rises, and you start to feel more awake—conversely, when it lowers, you begin to feel tired.
The reason this is important is that your room temperature and the heat retention of your bed can have an impact on your sleep. If you sleep too hot, that affects your body’s ability to go through its natural cycle, and you won’t wake up feeling rested. The best temperature for your room to be while you’re sleeping is around 65 degrees. More than anything, it’s essential to have a bed that doesn’t allow you to sleep too hot overnight.
