The Sleep Philosophy 4-inch Memory Foam Topper will transform your mattress from ordinary to extraordinary. The topper features 2 inches of 2.5 lb density temperature control memory foam layered onto another 2-inch 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. Memory foam is resistant to dust mites and is naturally antimicrobial. The 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 the slightly oversized topper comes in full mattress sizes to give your bed end-to-end coverage.
