Does this mattress sleep hot?

No, it stays cool for a foam-topped hybrid, scoring 9.6 out of 10 for cooling. The surface settles near 29.9 C, close to the cool end of its range, helped by an InfiniCool cooling sleep surface and 2 inches of gel-infused foam drawing heat off the top while air channels through the 1000-coil core instead of stalling in solid foam. It warms only modestly under you overnight, starting low and ending low.
