Featuring an advanced ContourFit design, the Beautyrest Hybrid Island Park provides more consistent comfort and support to help you find your optimal sleep position. The surface continually adapts, allowing you to engage with the memory foams for pressure relief throughout the night. For an undisturbed rest, Beautyrest's patented Pocketed Coil technology brings conforming support and promotes motion separation between sleepers. Additional gel foams inside provide comfort, support and breathability. As an added benefit, an energy foam below the coil unit creates a durable foundation for years to come. 10 Year Limited Warranty
