Does the cool-touch cover stop this mattress sleeping hot?

It keeps the first contact genuinely cool and helps overall, scoring 8.4 for cooling at a measured 32.7 C peak. The Cool-To-The-Touch removable cover and breathable comfort foam manage the surface, and the medium feel means you sink in some but not so far that foam wraps heat all around you. As an all-foam bed the solid core breathes less than coils, so a warm sleeper should expect some warmth later in the night.
