The Serta Dream Haven Whispering Pines Collection of Mattresses provides a quality mattress, using premium materials, at a great value. Individually wrapped coils provide support for correct body alignment allowing you to sleep longer. Comforting layers of foam, including Gel Active™ Gel Memory Foam, gently conforms to your body providing pressure relief. An extra layer of memory foam, Flex Band™ Memory Foam, is added to the center third of your mattress to provide even more support where your body needs it most. This would be a good bed for a back or side sleeper.
