The new Sealy 51162530 Medina Cushion Firm Twin was developed to provide comfort that lasts year after year. Get the lasting comfort your body desires and the support it needs. We start with a soft breathable knit fabric to provide a great sleep environment. Encased Stability Coils™ give you individualized support to ensure you wake up feeling rested and refreshed while eliminating motion transfer that can lead to disturbed sleep. OrthoZone II® Gel Infused foam provides another layer of comfort and stability you have come to trust from Sealy in addition to a full layer of memory foam for added pressure relief. New features such as the SolidEdge HD™ technology gives you more sleep surface and prevent the mattress from shifting side to side.
