Does this thick pillow-top sleep hot?

No, it sleeps cool, earning a perfect 10 out of 10 for cooling with measured peak surface temperature near 30.8 C. A breathable Tencel-blend cover wicks moisture while the micro-coil layer opens airflow beneath the plush comfort foam, so heat escapes rather than building up. Even at 16 inches with deep cushioning, the surface stays temperature-neutral, which is a real advantage for warm sleepers who still want a soft feel.
