Does this Chirofoam foam mattress sleep hot?

It runs slightly warm, its softest point, scoring 6.7 out of 10 for cooling with a measured 32.3 C peak surface temperature. With no spring layer to vent air through the middle, the breathable cotton-topped cover and the gel-infused top foam carry the whole cooling load. Treat it as temperature-neutral rather than a dedicated cooling bed. Hot sleepers may want a breathable protector or cooling sheets; it settles back toward the mid-20s C range overnight.
