Why Some Mattresses Trap Heat
During sleep, your core temperature gradually drops as part of the body’s circadian rhythm, signaling that it’s time to rest. But if heat becomes trapped near the skin, this cooling process is disrupted, often leading to sweating, restlessness, and frequent awakenings. The most common cause of heat retention in older or lower-quality mattresses is dense memory foam that closely contours to your body without a route for heat to escape. But there’s good news: modern cooling mattresses have breathable builds and use advanced heat-dissipating technologies to actively draw heat away from sleepers, providing all-night relief.

How Do Bear Mattresses Keep Sleepers Cool?
Cooling comfort is built into the Bear sleep experience. Across our mattress collection, you’ll find features like Celliant® covers that support your body’s natural temperature regulation, breathable foams with CertiPUR-US® certification, and advanced memory foam infusions (copper and gel) that actively draw out heat.

CoolForce™ Technology
For hot sleepers who want the best-of-the-best in cooling mattress technology, we also offer our CoolForce™ upgrade with select models. Phase change material (PCM) is added to the uppermost foam layer for dynamic relief throughout the night. Third-party testing shows that CoolForce™ can keep you up to 4 degrees cooler for 12 hours. NOTE: Our best cooling mattress, the Elite Ultra Hybrid, already includes this feature—no upgrade needed!
