The Sleep Innovations Marley is a 12-inch gel-infused memory foam mattress. It suits side sleepers who want pressure relief without excessive sink. Its standout trait is the cooling gel layer that helps regulate temperature.
Mattress Construction
The Marley has three layers. The top is a 2.5-inch gel-infused memory foam that contours to your body. The middle layer is a transition foam that provides support. The bottom is a 7.5-inch high-density foam base that adds durability. This construction aims to balance comfort and support.
Comfort and Support for Side Sleepers
Side sleepers need pressure relief at the hips and shoulders. The memory foam conforms to these areas, reducing pressure points. The medium firmness helps maintain spinal alignment. However, heavier side sleepers might find it too soft, leading to deeper sinkage.
