Does this hybrid sleep cool?

Yes, it is one of the coolest beds we have measured, scoring a perfect 10 out of 10. The surface read 29.8 C overnight and settled near 24.5 C, so it sheds heat rather than building it. A CoolFeel cover works the surface, a graphite-treated memory foam draws warmth from where your body touches, and a breathable micro-coil sheet sits under the top, over a 2550-coil core that lets air flow. One owner noted no hot sleeps.
