Does this latex foam mattress sleep hot?

No, it sleeps cool, scoring 9.3/10 on cooling with a measured peak near 28.7 C. The organic latex comfort layer breathes through its open pinhole structure far better than memory foam, and the organic cotton cover wicks heat rather than trapping it. As an all-foam bed the core moves less air than a coil mattress, but the latex surface carries the cooling convincingly through the night.
