The Superior mattress is where exceptional craftsmanship and luxurious comfort come together. It begins with our advanced QuadCore® coil system with TrueEdge360™ support, delivering consistent, edge-to-edge stability across the entire sleep surface. Multiple high-density support foam layers create a strong foundation, allowing the comfort layers above to perform at their best. As a true pillow top design, the Superior features an inner panel that protects and preserves the integrity of the comfort layers over time. The top comfort system blends copper gel-infused latex with a zoned micro-coil, providing unmatched pressure relief, targeted support, and a cool, responsive feel for a deeply restful night’s sleep.
