Abstract
A mattress foundation with a perimeter structure has a frame, springs mounted upon the frame, and a grid supported by the springs, and perimeter structure at a perimeter of the frame which extends from the frame to the grid, forming an exterior wall which extends from the frame to a border wire of the grid. When the perimeter structure is made of structural and reflexive material such as closed-cell foam, it co-acts with the grid and springs and provides additional support to the perimeter region of the grid and foundation. The exterior wall of the perimeter structure forms a solid surface over which padding or upholstery is placed.
