The Madison Hybrid mattress has been encapsulated, where the outer foam border helps to improve the mattress durability, which reduces the likelihood of sagging and prevents a feeling of “roll-off” and instead provides consistent edge-to-edge support along the entire mattress surface.The Madison Hybrid has been layered with luxury memory foam and combined with a refined pocket spring system which ensures you get head to toe support.The individually responsive pocket springs combined with foam fillings ensures an overall comfort and support for the body.Offering pressure relief by spreading your weight across the whole of the mattress, this also prevents roll-together, so when your partner turns you won’t be disturbed, ensuring you both get a good night’s rest.
