Does this mattress sleep hot?

No, it reads neutral-to-cool, scoring 8.5, with surface temperature peaking around 31 C. There is no specialty cooling cover, but the thin 1.25-inch comfort layer keeps you close to the 720-coil core, and air moves freely through that pocketed-coil system instead of being trapped in a thick foam slab. For a firm hybrid built to a budget, staying this temperate overnight is a solid, structural result rather than a marketing claim.
