11 Best Cooling Mattresses for Hot Sleepers [2024]

The verdict: The Purple RestorePremier™ Hybrid ranks as the best cooling mattress. Its cooling cover, GelFlex® Grid design, and coil system create a breathable, comfortable sleeping surface with superior temperature balancing.

Picture this: You finish brushing your teeth before bed, turn off all the lights, and head to your bedroom — only to find your dog preheating your spot. Say goodbye to that beloved nighttime chill in your sleep space because Fido just had to warm it up. If you had the best cooling mattress, this wouldn’t even cross your mind. Your mattress would still be cool. 

The best cooling mattresses are often hybrid beds made of latex, polymer, and other cooling materials. Compared to hybrid mattresses, memory foam typically traps body heat. However, there are memory foam options infused with cooling agents or designed in a way to promote airflow.

How To Choose a Cool Mattress

Choosing the best mattress can be time-consuming, but considering how much time we spend in bed, it proves to be a valuable, rewarding process. In addition to cooling features, you’ll want to consider the other aspects that make up your ideal bed — like pressure relief, support, and overall quality.

Here are a few considerations to remember throughout your search for the best cooling mattress:

• Mattress types: Traditional memory foam mattresses trap body heat. The coil systems in hybrid mattresses typically allow for better airflow. Latex mattresses and airbeds are good alternatives as well.
• Cover materials: Look for cooling qualities, like moisture wicking, breathability, or infusions with cooling elements like gel, copper, or charcoal. 
• Trials: Many mattress retailers offer trials so you can verify that the mattress meets your needs and stays cool all night.
• Quality: High-quality mattresses are made of premium materials that help ensure lasting comfort over the years. It’s commonly believed that one should replace their mattress every 10 years. That can be true depending on the quality. Commodity mattresses often don’t last that long and should be replaced sooner. Though you may pay more upfront, opting for a higher-quality mattress can help your wallet and comfort in the long run.

How To Make Your Bed Cooler

Can’t swing a new cooling mattress purchase quite yet? Don’t sweat it. Thankfully there are other ways to cool down your sleep environment, so you can get a good night’s rest.

• Keep your bedroom’s thermostat low: The best temperature for sleep is between 66°F and 68°F.
• Use a tower fan to circulate the air: If you don’t have central air conditioning, a fan will bring a cooling breeze as you sleep.
• Opt for breathable, cooling sheets: Look for blends of bamboo, cotton, and linen fabrics, like Purple SoftStretch® sheets. This goes for blankets as well.
• Sleep with a cooling pillow: Some pillows are made of the same materials as cooling mattresses the Purple Harmony™ cooling pillow is the perfect example: it uses the GelFlex Grid®, just like in Purple’s cooling mattresses, to provide cool, supportive comfort for your head.

FAQ

What Is a Cooling Mattress?

Cooling mattresses are made of materials that balance or lower body temperatures while sleeping and provide the support you’d expect from a mattress. Various cooling technologies are available today, from covers woven with cooling fibers, to layers of gel-infused foam, to unique grid designs.

What Mattress Is Best for Night Sweats?

Purple mattresses can be great for those suffering from night sweats thanks to the GelFlex® Grid. Made from proprietary temperature-neutral material, the GelFlex® Grid naturally draws excess heat away from the body without trapping it in the mattress. Since it feels cool all night long, you may find complete relief from night sweats.

Why Is My Bed So Hot?

Your bed might seem hot because it’s retaining your body heat, leaving you too hot to sleep well. Some mattress materials — like memory foam — trap heat more than others. While high-density memory foam can be supportive for some sleepers, if you run hot, look for hybrid, latex, or foam mattresses with added cooling elements. Then layer them with breathable bedding. 

Do Cooling Mattresses Really Work?

The best cooling mattresses do actually work, but some mattresses that claim to be cooling will still leave you drenched in sweat throughout the night. That’s why we compiled this list. It’s not enough for a mattress to feel cool to the touch — it should work to stay cool while your body rests on it. 

As discussed, memory foam mattresses are at a disadvantage when it comes to cooling. They’re dense and often retain heat. Latex or hybrid mattresses typically sleep the coolest. The mix of materials offers support, airflow, and balanced temperatures. Purple mattresses are proven to dissipate heat, so you can sleep peacefully and cool all night long.
