Does this mattress sleep hot?

No, cooling is its strongest trait, scoring a perfect 10 out of 10. Heat escapes through three paths: gel-infused comfort foam pulls warmth from the surface, the pocketed-coil core lets air circulate instead of trapping it, and a tempered-steel micro-coil layer adds airflow no all-foam bed can match. The Tencel-blend cover wicks moisture on top. Settled surface temperature stays in the cooler-than-average 23 to 27 C range.
