A bedding or seating product comprising a centrally located spring core, edge support means located around the perimeter of the spring core, filling material located above and below the spring core and an upholstered covering. The edge support may be either a string of springs, a pair of spiral edge supports or plastic edge reinforcements. The edge support means extends above and below the upper and lower surfaces of the spring core thus creating a higher peripheral edge than the central portion of the spring core. Layers of filling material are inserted over the central portion of the spring core in order to create a uniform upper and lower surface.
