The higher density creates finer body contouring, with each coil independently responding to weight and movement across three distinct support zones. For side sleepers, the shoulder zone yields to allow the upper body to settle into the plush surface while the lumbar zone provides firmer resistance through the gel foam band, keeping the spine aligned from neck to hip. Contouring memory foams between the CoolFeel cover and coil system absorb remaining pressure, eliminating the shoulder numbness and hip stiffness that cause frequent waking during the night.\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\u003eUltimate Plush\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMattress Type\u003c\/td\u003e\n\u003ctd\u003eInnerspring with Contouring Memory Foams\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComfort Level\u003c\/td\u003e\n\u003ctd\u003ePlush\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCoil System\u003c\/td\u003e\n\u003ctd\u003e850-Coil Density Individually-Wrapped System, 3-Zone Support\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\u003ePressure Relief\u003c\/td\u003e\n\u003ctd\u003eContouring Memory Foams\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 (850-Density Individually-Wrapped Coils)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBest For\u003c\/td\u003e\n\u003ctd\u003eSide 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 Ultimate is the top-tier model in the Perfect Sleeper lineup, designed for consistent, restful sleep with the most advanced comfort layers in the collection.

The Enhanced uses Cool Twist Gel Memory Foam for cooling instead of CoolFeel and keeps the 825-coil count. Both include the gel foam lumbar band and extra-deep foam rail.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill the plush surface cause my body to sag into the mattress?\u003c\/strong\u003e\u003cbr\u003eNo. The plush comfort layers sit above the rigid 850-coil system and gel foam lumbar band. The surface conforms to the body without compromising the structural support underneath. The extra-deep foam rail also prevents edge compression when sleeping near the sides.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the Ultimate Plush too soft for occasional back sleeping?\u003c\/strong\u003e\u003cbr\u003eThe 3-zone coil system provides firmer resistance through the lumbar region regardless of the plush surface feel. Back sleepers who primarily sleep on their side but occasionally roll onto their back will find adequate support through the zoned coil system.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the CoolFeel cover work with memory foam layers?\u003c\/strong\u003e\u003cbr\u003eYes. Memory foams absorb body heat as they contour. The CoolFeel cover intercepts that heat at the surface before it saturates the foam, while PillowSoft Aire Foam promotes airflow from within. The dual approach prevents the heat buildup that traditional memory foam mattresses are known for.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere can I buy the Serta Perfect Sleeper Ultimate Plush with free shipping?\u003c\/strong\u003e\u003cbr\u003eCasa Bella Decor is an authorized Serta Perfect Sleeper retailer based in Melissa, Texas, offering 20% OFF and free shipping across all 50 US states.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdiv class=\"cta-box\"\u003e\n\u003ch3\u003e20% OFF \u0026amp; Free Shipping — Don't Miss This\u003c\/h3\u003e\n\u003cp\u003eShop the \u003cstrong\u003eSerta Perfect Sleeper Ultimate Plush\u003c\/strong\u003e — the most advanced \u003cstrong\u003eplush cooling mattress\u003c\/strong\u003e in the collection with 850-coil 3-zone support.
