For a feeling of unmatched responsive cradling that follows your body's every move, our all-new iComfort SmartSupport Hybrid beds combine our exclusive EverFeel® Triple Effects Gel Memory Foam with our new SmartSupport Memory Coil System, the world's first system that offers support with the unique feel and response of memory foam. These advanced technologies are combined with the familiar look and feel of a cushion firm mattress. Your body gets the individualized support it needs from our most advanced Duet® Elite Individually Wrapped Coil Support System. It features strategically placed coils to balance comfort and support across the mattress, while BestEdge® Foam Encasement ensures an edge-to-edge sleeping surface. The HB500Q model offers a cushion firm" feel, which combines a slightly firmer sleep surface with subtle, pressure relieving comfort.
