How to Choose a Mattress for Side Sleepers

Side sleepers need pressure relief at the hips and shoulders. Look for a mattress with a comfort layer that contours without excessive sink. A medium firmness often works best. Consider your weight, as heavier sleepers may need a firmer option. Also, check for motion isolation if you share the bed.

Understanding Cooling Gel Memory Foam

Cooling gel is infused into the foam to draw heat away from the body. It helps regulate temperature during sleep. The Marley uses a gel layer on top of the support foam. This design aims to keep the surface cooler than traditional memory foam. However, individual results vary based on room temperature and bedding.
