Does a foam mattress like this sleep hot?

It sleeps cooler than most foam beds, scoring 8.7 for cooling, with peak surface temperature held in the 30 to 33 C range. An inch of gel-infused foam at the top draws heat off the surface your body meets. Being all-foam, it will not breathe like a coil hybrid that moves air underneath, but among foam mattresses it runs notably temperate rather than warm, especially given its slim 7-inch profile.
