The ComfortCare® Rockingham Firm Mattress, by Restonic, provides a firm and supportive sleep surface. A great value, with many premium components without the premium price. Using the 800 series individually wrapped coil unit, you'll feel the support across the entire mattress. Layers of support Foam, including Gel Memory Foam and AirFlow Fiber, provide pressure relief and a cooler sleep surface. This is a very good mattress for a back or stomach sleeper.
