The Scott Living 11″ Hybrid firm mattress features a layer of gel-infused memory foam, which is more resilient than traditional memory foam. While traditional memory foam can leave the sleeper immobile due to its slow reaction time, gel-infused memory foam allows the sleeper to move freely. As a result, it’s suited to a variety of sleep positions, adding to its comfort and versatility. The exclusive 2Cool® technology helps regulate body temperature, creating a cool, comfortable sleep environment throughout the night. By gently and consistently moving heat away from your body, you’ll enjoy a full night of restful, undisturbed sleep. The Twin Support Q5 coil system incorporates individually wrapped coils to give a customized level of support as well as motion separation, while the Twin Support Edge is a band of outer coils that have two coils wrapped together, to help avoid the feeling that you are rolling off the edge of the bed. Extra Firm Foam provides additional support and firmness ideal for back sleepers. It also keeps the sleeper on top of the mattress and reduces the “sleeping in the mattress” sensation.
