If you’re struggling to get quality sleep because you wake up aching and stiff, then the foam isn’t adapting to your body shape the way it’s supposed to anymore.

More Aches and Pains

High-density foam absorbs the motion when you change position, so one partner doesn’t wake the other. If the foam mattress you currently use isn’t offering reduced motion transfer, this could be a sign that it’s wearing thin
