I flip the pillow all night looking for the cool side

Flipping is a height problem disguised as a heat problem. Memory foam softens as it warms, so a foam pillow that was the right height at bedtime is measurably lower an hour later — and the cool side feels better partly because it has not yet collapsed. The relief is real and it is not only about temperature.

What the pillow has to do

• loft in measured range — Pillow loft within the range your own measurement implies. This is first for every constraint in this cluster, because no surface is soft enough to rescue a pillow your head has already flattened.
• position tolerant support — Support that does not depend on hitting one exact spot, so rolling over does not mean re-finding a position in the dark.
