Both the Dream and Comfort mattress are foam, pressure-redistribution mattresses with a strong foundation layer, firm perimeter edges, and a Visco memory foam layer with cooling gel to reduce pressure and maintain optimal temperature. The Dream mattress has the added benefit of a bamboo quilt-top which more closely resembles a home-style mattress and makes turning and repositioning in bed easier. The Dream mattress is also reversible, with a softer and firmer side to suit your preference.
