For stomach sleepers, this prevents the pelvis from sinking deeper than the chest, which causes lower back strain. For back sleepers, the gel foam lumbar band reinforces the lower back and hip zone to maintain the natural curve of the spine. The CoolFeel fabric cover feels cool to the touch on contact, drawing surface heat away before it reaches the foam layers. Combined with the airflow channels in PillowSoft Aire Foam, the cooling system works from the cover down through the comfort layers.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Specifications\u003c\/h2\u003e\n\n\u003ctable class=\"cb-specs\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSerta Perfect Sleeper Collection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eStandard Firm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMattress Type\u003c\/td\u003e\n\u003ctd\u003eInnerspring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComfort Level\u003c\/td\u003e\n\u003ctd\u003eFirm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil System\u003c\/td\u003e\n\u003ctd\u003e825-Coil Density Individually-Wrapped System\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCover\u003c\/td\u003e\n\u003ctd\u003eCoolFeel Fabric (Cool-to-the-Touch)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComfort Layer\u003c\/td\u003e\n\u003ctd\u003ePillowSoft Aire Foam (Airflow-Promoting Design)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLumbar Support\u003c\/td\u003e\n\u003ctd\u003eGel Foam Lumbar Support Band (Lower Back and Hips)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEdge Support\u003c\/td\u003e\n\u003ctd\u003eExtra-Deep Foam Rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotion Isolation\u003c\/td\u003e\n\u003ctd\u003eYes (825-Density Individually-Wrapped Coils)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBest For\u003c\/td\u003e\n\u003ctd\u003eStomach and Back Sleepers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAssembly\u003c\/td\u003e\n\u003ctd\u003e100% USA Assembled\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSizes\u003c\/td\u003e\n\u003ctd\u003eTwin, Twin XL, Full, Queen, King, California King\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping\u003c\/td\u003e\n\u003ctd\u003eFREE Delivery (USA-wide)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cdetails\u003e\n\u003csummary\u003eDetails \u0026amp; Care Instructions\u003c\/summary\u003e\n\u003cdiv class=\"dt-inner\"\u003e\n\u003cp\u003eThe Serta Perfect Sleeper is designed for consistent, restful sleep for every type of sleeper.
