Most cooling claims stop at the cover. The Signature IQ runs cooling the whole way down: a cool-to-the-touch cover, copper-infused memory foam, graphite latex and Kikoo strips stacked over a gel shell of independent cubes that keeps air moving under you all night.

Those cubes move on their own, which is what kills motion transfer when the other person rolls over. A five-zone pocketed coil unit and a foam-encased edge handle alignment and edge support, and Qube backs the mattress with a 20-year warranty. It is handcrafted in the Pacific Northwest and offered here in King and Queen, so a primary bedroom and a guest room can match without mixing brands. Built for hot sleepers who share a bed and want real contouring without a trench forming down the middle of it.
