Does this plush pillow-top sleep hot?

No, despite the deep 4-inch comfort section it sleeps cool, scoring 9.4. The WinterCool performance fabric and cooling-treated graphite memory foam draw heat out of the layer pressed against your body rather than leaning on the cover alone. Below, the 1000-coil pocketed core leaves open channels for air to move instead of the dead-air trapping an all-foam build creates. The plush foam is engineered with cooling chemistry so it does not bank warmth overnight.
