Created with highly advanced sleep materials, Therapedic's Keswick hybrid mattress makes a perfectly plush bed for your child. Its sanitized finish continually inhibits the growth of odor-causing microbes and bacteria using zinc to keep your mattress fresh. Perfect for children sharing a bed, TheraWrap Edge to Edge coils reduce motion transfer to prevent partner disturbance. Each individual coil moves independently, conforming to fit the sleeper. Added TheraCool Memory Touch Visco gel foam maximizes comfort, combining pressure relieving and heat-wicking material in a cooling foam.
