The rise in popularity of memory foam mattresses has increased consumer concern over mattresses’ tendency to “sleep hot” (foam is known to trap heat). To combat this, many foam mattress brands now include a layer of cooling gel to help sleepers stay cool.

If you’re shopping for a mattress that keeps you cool, you have plenty of options today. Many of the best mattresses for hot sleepers are traditional spring mattresses, which have good air circulation and don’t have a dense layer like foam mattresses. In general, cooler mattresses (foam, spring or hybrid) also have layers of breathable materials like latex and bamboo.

  • Warranty: 10-year limited
  • Test period: 100-night trial

What we like
The foams used in the Cocoon Chill mattress are certified by the CertiPUR-US program. The mattress is available in medium-soft and extra-firm comfort levels, so you don’t have to sacrifice comfort for your sleep style to stay cool at night.
What people say
Those who’ve highly rated Cocoon by Sealy on our site mention the quality product and brand loyalty. Bernice of Wisconsin wrote: “I always purchase Mattress by Sealy. I’ve had mine for over 8 years and still going strong. That’s the only type mattress I’ll ever buy. Everyone I talk to always tell them to purchase sealy. I understand you should change your mattress every 10 years but if I don’t need to I don’t. I am considering purchasing another one in another couple years.”

Our favorite innerspring hybrid mattress: Saatva Classic Luxury Firm Saatva Mattress

Saatva customers on ConsumerAffairs seem to appreciate the company’s prompt and attentive customer service — like Jan from Florida : “Delivery from order just under 3 weeks. Within a few days my husband felt there was a defect. ... I sent photos to a customer service representative and I was called right away.

"Kristen was very good, asked a few questions about our sleep history, and suggested we reorder the ‘Firm’ which we did. Again, timely delivery. We are very satisfied with the replacement product and especially the excellent service."

What people say
Happy Nest Bedding customers on our site mention the brand’s responsive service and quality products. Tom of Virginia said: “They provided a quality mattress with very good comfort (almost perfect for us) and we have been very happy with it. We contacted support early on but found once our bodies got used to the mattress we didn't need to follow back up with them. They were very responsive to my inquiry.”

Our favorite mattress for couples: Helix Dusk Luxe Helix Mattress
  • Type: Foam
  • Price (queen): $2,373.80 (as of publication)

What people say
Helix reviewers on our site seem to like the ease of delivery and setup as well as the comfort features. Here’s what Amanda of New Jersey had to say: “I ordered the mattress that the online quiz fit me to and within about a week and a half my mattress was delivered. Unboxing was straightforward, you slide it out of the box, align it with your base and cut open the plastic.

"It pops open and comes to life as soon as you cut the plastic. It took about an hour to open all the way up and I put sheets on it and went to bed after 2 hours. There were no strange odors or off gassing that I noticed. … After about a week, my back had completely stopped hurting and so did my neck.”

What causes body heat at night?

Body temperature increases and decreases on a 24-hour cycle. Typically your body temperature is lower at night, which helps to facilitate sleep. From the temperature outside and inside your home to your activity right before going to bed (hint: don’t exercise right before bed), many factors can play a role in increasing body heat at night, and an increased temperature is likely to cause disruptions in your sleeping pattern.

Softer mattresses — or any that contour to your body — are more likely to retain heat. Similarly, heavier people are more likely to sink deeper into mattresses, causing that contour effect, which can cause them to sleep hotter than lighter individuals.

Which cooling mattress should I choose?

If it’s a cool night’s sleep you’re seeking, you have options. Whether you want a gel, memory foam, spring or hybrid mattress, the technology is advanced enough that most quality brands have a cooling feature in place to keep you comfortable throughout the night, regardless of the season. Each of the mattresses listed above was selected for its advanced cooling technology, so it’s hard to go wrong. We recommend picking the one that best fits your sleeping position and support needs.

What kind of mattress should I get if I’m a side sleeper?

According to Martin Seeley, founder of MattressNextDay: “Foam mattresses are best for the side sleeper, providing adequate cushioning and support. Foam works well for those who need pressure relief because it conforms to their body shape. For people who tend to sleep hot, foam may be a good option since the material is breathable and will help keep them cool during the night.”
