The Comfort Classics Four-Inch Memory Foam Topper will transform your mattress from ordinary to extraordinary. Our topper features two inches of 2.5-pound density temperature-sensitive memory foam layered onto another two inches of high-density support foam. The memory foam adjusts to your body temperature to help alleviate pressure points and relax muscles for a more soothing night of sleep. Experience all the benefits and comfort of a high priced memory foam mattress at a fraction of the cost. Memory foam is resistant to dust mites and is naturally antimicrobial. Our topper also comes with a zippered removable cover that features 3M Scotchgard moisture management protector. The protector gives the cover stain release properties while providing moisture management for enhanced comfort. The cover has a non-skid backing which locks the topper in place on your mattress.
