The Hybrid Technology of the 10" Pillowtop Innerspring Mattress offers the best of both worlds, combining the support of a traditional coil spring mattress with the contouring comfort of cooling GelLux™ Foam. Pocketed coils provide consistent distribution of support and reduce motion transfer for undisturbed sleep. Edge support foam maximizes sleep surface and prevents edge sagging while sitting at the end of your bed. The cooling GelLux™ Foam is made using a state-of-the-art process that combines cooling liquid gel with engineered latex. This layer of GelLux™ Foam adds greater overall cushioning and helps maintain an ideal temperature, giving you a cool and more restful night's sleep. This 10" Pillowtop Innerspring Mattress conveniently ships compressed and rolled in a single, compact box for easy transportation and goes from box to bed in minutes. Simply unpack your mattress from the box, unroll by carefully cutting the heavy duty securing straps, remove the protective plastic bag, and watch your mattress begin to expand before your eyes. 10 Year Warranty.
