Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://coolsleeppicks.com/how-we-research#our-score Side sleepers need enough give at the hips and shoulders to stay aligned, but soft foam often traps heat right where you press in. A cooling topper aims to add that pressure relief without leaving you warm and sweaty. This guide balances both needs, covering toppers that cushion side sleepers while managing heat, plus what to look for in thickness and feel. ## Picks ### 1.
