The Best Cooling Mattress Award goes to the bed that's the most effective at providing a cool sleep surface all night long.

57% of Americans report sleeping hot at least occasionally so cooling beds are in demand.

Bear knows how to keep you cool and comfortable

The Bear Elite with Celliant is a 14" hybrid mattress made of pocketed spring coils, copper-infused memory foam, dynamic transition foam, high-density support foam, wrapped up in a cover containing Celliant fibers.

Celliant is a unique feature of the Bear Elite Hybrid that even the best luxury mattresses online don't have. But what is it and how can it help you sleep? Celliant is a thermo-reactive synthetic fiber that absorbs body heat and transfers it into infrared energy, which is then reflected back to the body to aid muscle recovery. Hence why the Bear Elite Hybrid is marketed towards athletes.

Together, these specialist cooling innovations aid temperature regulation to help keep you at an optimal sleep temperature through the night. During our lab and home tests, this mattress has kept our fussy mattress reviewers cool and comfortable.

Cooling aside, the Bear Elite is an exceptionally cushioning, contouring and supportive bed. In our pressure relief tests, it earned a 4.5 out of five score which translates to excellent pressure relief and lumbar support. This means when you lay on the bed, your body weight is evenly distributed so pressure or pain doesn't build up in your joints and back.

As one of the top-rated mattresses of the year, Bear only competes with the creme-de-la-creme of beds — we're talking the 5-star Saatva Classic (rated our best bed of the year) and the outstanding value DreamCloud Classic.

Specifically considering temperature control, the Bear Elite only beat the Saatva Classic by a small margin. Our test data revealed that while the Bear Elite quickly absorbs and dissipates body heat, the Saatva regulates temperature more consistently. Therefore, we recommend the Bear to chronic hot sleepers suffering night sweats and the Saatva to average hot sleepers who get the occasional hot flash.
