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 Activeª Gel Memory Foam, gently conforms to your body providing pressure relief. An extra layer of memory foam, Flex Bandª 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.
