The ComfortCare® Venus Firm Mattress by Restonic, provides a wonderfully Firm yet comfortable sleep surface. A great value, with many premium components without the premium price. Using a 1,000 series individually wrapped coil unit, you'll feel the support across the entire mattress. Layers of Soft 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.
