A classic two sided mattress, the Erin Cushion Firm, from Restonic's ComfortCare Collection, is a solid long wearing mattress. Supported with Foam Encased Individually Pocketed Coils, designed with more coils in the center third for more support. Firm layers of pad and foam help reduce body indention helping the mattress feeling new longer. With it's Outlast® Cover, you'll sleep cool and dry as this special material absorbs, stores and releases excess heat your body gives off. This would be a good mattress for a stomach sleeper or a back sleeper who prefers a firmer feel.
