ABSTRACT:
An edge support system for a mattress foundation. The edge support system includes a pair of torsion elements, each including a central torsion segment, with the torsion segments being secured to one another, and with the torsion elements being formed as mirror images of one another, with legs being attached to the top and bottom border members of the mattress foundation. A secondary expansion spring is connected between the attached torsion segments and an intermediate rod located midway between the border members of the foundation. The gauge of the wire forming the torsion elements and the strength of the expansion spring determine the amount of support by the edge support system. A plurality of the system can be spaced about the periphery of the foundation to provide greater firmness in areas needing enhanced stiffness.
