ABSTRACT:
A box spring assembly which includes a generally rectangular frame, a welded wire grid disposed above and aligned with the frame, a plurality of upwardly extending limited deflection wire springs which are mounted at their lower ends on the frame and at their upper ends are secured to the welded wire grid, and corner springs which are yieldable and are supported on the corners of the frame so as to support the corners of the grid. Each of the limited deflection springs is formed at its upper end with an attaching portion that is readily secured to the grid by conventional clips and includes wire sections which provide additional spaced supports for the grid. Improved cross rails in the frame support the springs and improved corner springs support the corners of the grid.
