Three steel strands wound into one coil to absorb energy, reduce motion and provide exceptional resilience for support, durability and undisturbed sleep.  BlackICE™ Hybrid Technology:  Beautyrest's most advanced cooling technologies maintain temperature so that you can sleep cooler and more soundly. Enjoy an immediate cooling sensation from the cool-to-the-touch cover, then stay cool and comfortable throughout the night as the RightTemp™ Memory Foam pulls heat away from your body.  ContourFit™ design exclusive to Beautyrest allows you to find your optimal sleep position. The superior stretch and recovery surface adapts with you throughout the night, allowing you to engage more closely with the pressure relieving memory foams for a deeper, easier sleep.  Beautyrest Black® Hybrid features more, higher quality memory foams than any of our other hybrid mattresses, helping to reduce pressure points in your hips and shoulders.
