Restonic Firm Hybrid Mattress with Pocketed Coils Cooling Foam and Lumbar Support

A firm sleep surface doesn't have to mean a punishing one — this 13-inch hybrid from Restonic layers multiple foam technologies over an individually pocketed coil system to deliver deep lumbar support alongside genuine temperature regulation. The reinforced center third and 360-degree edge support system make the entire sleep surface usable, not just the middle, which is a meaningful advantage for couples or sleepers who shift positions through the night.
