A classic two sided mattress, the Erin Plush, 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. Super Soft Gel quilted sleep surface helps you sleep cooler. 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 back sleeper.
