Does this firm model sleep hot?

It runs cooler than a plush foam bed, scoring 7.1 on cooling. The firmness helps: because you sleep on top of the foam rather than sinking in, less of your body gets wrapped in trapped heat. The Cool-To-The-Touch removable cover manages the surface, settling into roughly 25 to 30 C overnight. Be aware the dense all-foam core breathes less than a coil bed, so a very hot sleeper will notice it holds some warmth.
