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 sinking too much. A medium-firm feel often works best. Check the materials: gel-infused foam helps with heat retention. Also, consider motion isolation if you share the bed.
What to Expect from the Marley Mattress
The Marley arrives compressed in a box. You should allow 24 to 48 hours for it to fully expand. Some initial odor is normal and fades within a few days. Owners report that the mattress sleeps cooler than traditional memory foam. The surface feels soft initially but firms up with support underneath.
