Restonic Comfort Care Firm Hybrid Mattress with Pocketed Coils and Cooling Foam Layers

A firm sleep surface doesn't have to mean sacrificing comfort, and this 13-inch hybrid from Restonic makes that case convincingly. Multiple foam layers work alongside a 700-coil innerspring system to deliver targeted lumbar support, active heat dissipation, and a reinforced perimeter that holds its shape from edge to edge — qualities that matter most to back sleepers and anyone who runs warm at night.

• W 76 x L 80 x H 13 inches (King size)
• 700 individually wrapped pocketed coils with 360° SuperEdge reinforced perimeter for full-surface support and edge-to-edge stability
• Exclusive Marvelous Middle® construction reinforces the center-third of the mattress with 25% more lumbar support and reduced motion transfer between partners
• Phase change material technology actively absorbs and releases body heat to regulate sleep temperature throughout the night
