Does this mattress sleep hot?

No, it runs noticeably cool, scoring 8.7 for cooling. The SoftLux breathable cotton cover over an airy poly comfort layer does the work, and the slim profile does not bank much body heat to begin with. Peak surface temperature holds in the 30.1 to 32.9 degrees C range, among the cooler foam results, with no gel gimmick. By morning the surface settles into the upper 20s, shedding the night's warmth.
