Does this extra-plush pillow top sleep hot?

No, it runs cool for such a soft, deep-cradling bed, scoring 9.9 out of 10 for cooling. The top 3 inches of gel-infused foam draw heat off the skin while the 1000-coil pocketed core below keeps air circulating instead of trapping it like a solid foam slab would. Gel over an airy spring core is the layout that sleeps coolest, which is notable since deep plush beds usually hold more heat.
