Crown Comfort 12-inch Memory Foam MattressCategory: Cal King Memory FoamElevate your nightly experience with this premium 12-inch queen-size memory foam mattress. Crown Comfort's memory foam provides a great sleeping surface. In normal temperatures it is somewhat firm, but when you lay down, it starts reacting to the temperature of your body and begins to mold itself to your shape. Then, weight is evenly distributed along the surface, relieving pressure points and helping you to sleep more without tossing and turning. A significant feature of this mattress is our pressure relief system that you can actually feel when you lay on the mattress. Special areas inside the mattress are accommodating to the areas of your body that create pressure points: Your shoulders and hips. The pressure relief foam really does minimize these pressure points. Pressure relief system virtually eliminates all pressure points to ensure a comfortable night sleep.Mattress layers: 2.5-inch Memory Foam 3-inch Super soft foam with pressure relief system 6.5-inch High Density PU Foam.Dimensions: 12 inches high x 60 inches wide x 80 inches longRecommended Foundation Type: Platform, Bed Slats, Adjustable, Box SpringProduct Features: No Tools AssemblyDelivery Method: Memory Foam - Small ParcelThickness: 12 InchMattress Type: Memory FoamSupport: MediumSize: QueenResistant to dust mites, naturally antimicrobialTemperature-smart memory foam responds to body heat and movement, reshaping to distribute body weight and relieve pressure points to improve circulationNever needs turningMemory Foam Tips: Arrives tightly packed in portable box for customer convenience.Remove from packaging within 72 hours to maximize expansion.You can sleep on it the same night it is unwrapped, however allow 48 hours to fully return to its original shape.Vacuum sealing sometimes traps odors.
