The triple-layer design of the 8" Marley Mattress keeps you cool and supported all night long. The gel memory foam top layer and supportive middle layer with airflow channels provide a cooling effect, helping to maintain a comfortable climate while you sleep. From the hypoallergenic cover to the robust base, this mattress is built for lasting durability and comfort. Memory foam is proven to relieve pressure points, easing the impact on your knees, hips, and shoulders in any sleep position. It also prevents motion transfer, allowing you and your partner to sleep undisturbed all night long.
