Abstract
The combination with a spring assembly of pairs of structures designed to be applied transversely to the top and bottom supporting surfaces at one or more longitudinally spaced intervals to enhance resistance to sinking of the supporting surfaces, bowing at the longitudinal sides and collapse between the surfaces at the longitudinal sides due to pressure applied perpendicular to the supporting surfaces, said structures each comprising a stiff, inextensible wire of circular or flat cross section resistant to flexing and at one end a compression-resistant spring, said structures being disposed in pairs with the one structure crossing the top and the other crossing the bottom and with the compression-resistant spring of one situated between the supporting surfaces at one side and of the other situated between the supporting surfaces at the other side and fasteners connecting the structure to the assembly.
