The Sleep Philosophy FLEXAPEDIC 4" Memory Foam Topper will transform your mattress from ordinary to extraordinary. Our topper features 2 inches of 2.5 lb. density temperature sensitive 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 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 topper in place on your mattress. Another feature we know you'll appreciate is that our topper comes in full mattress sizes to give your bed 'end to end' coverage.
