The Founders is built for those who value maximum support by utilizing an extra-firm steel coil. Our highest density of firm poly-foams are layered tightly over the spring and topped with a structured quilt. This combination is excellent for back sleepers as it creates a stable feeling on top of the mattress without sinking into the layers. Additional support braces on all sides are installed for minimal compression when sitting on the edge of the bed to perform your daily routines.
