Cooling Technology
The Marley features a top layer of gel-infused memory foam. Gel beads absorb and dissipate body heat. Owners report sleeping cooler than on traditional memory foam. However, it is not as cool as innerspring or hybrid mattresses. If you sleep very hot, consider a mattress with active cooling features.
Support and Firmness
This mattress rates around medium on the firmness scale. It contours closely to the body, providing pressure relief. Side sleepers typically find it comfortable. Back and stomach sleepers may need more support. The support foam base adds durability but does not offer strong edge support.
