Serta Perfect Sleeper’s exclusive Continuous Support Innerspring is designed using rows of continuous coil springs that run head to toe. The head-to-toe construction works to reduce motion transfer from one partner to another. The three zoned innerspring provides superior support and works to maintain proper spinal alignment throughout the night. Serta’s Advanced Comfort Quilt is a patented quilt layer designed to deliver superior comfort at the sleep surface while reducing the tossing and turning that can disrupt your sleep. This helps to reduce pressure points that cause tossing and turning so you can get a more comfortable and restful night’s sleep. Total Edge Foam Encasement creates a total edge-to edge sleeping surface so you have more room to stretch. Serta’s space-age Visco-elastic Memory Foam gently conforms to your body and contours to your sleeping position. Serta Perfect Sleeper has a 10 year non prorated warranty, and is a Consumer’s Digest Best Buy.
