The Sleep Philosophy 4" Memory Foam Topper will transform your mattress from ordinary to extraordinary. Our topper features 2 inches of 2.5 lb. density temperature control memory foam layered onto another 2" 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’s sleep. Experience amazing value and softness at a fraction of the cost. Our topper also comes with a zippered removable cover that features a 3M Scotchgard™ moisture-wicking management protector. The protector gives the cover stain release properties while providing moisture management for enhanced comfort and rich coziness. The cover has a ‘non-skid’ backing which locks the topper in place on your mattress. Another feature we know you’ll appreciate is that our slightly oversized topper comes in full mattress sizes to give your bed end-to-end coverage. Our packaging technology allows the mattress topper to be efficiently compressed into one box that’s easily shipped to your door. Simply unbox, unroll, and this mattress topper does the rest, expanding to its original shape within 72 hours.
