Abstract An improved spring is provided which may be used in cushions, mattresses, or box springs which includes a limiting internal member. This limiting member assist in limiting the longitudinal deflection of the springs. Also provided are snapped-fitting connections between the spring and a grid for use within a box spring. Also provided is a "floating" portion of a peripheral border wire, particularly suitable for use in a pair of box springs beneath a king-size mattress unit. Also provided is a corner guard which provided support for upholstered fabric on a box spring. Finally, an improved borderwireless mattress using a peripheral band is provided, which allows the mattress to bend more easily, without disadvantageous setting of its border wires.
A box spring for supporting a mattress, comprising: a base; a wire grid including a perimeter border wire having at least one corner; at least one coil spring for supporting said border wire above said base; upholstery material at least partially covering said mattress at the location of said border wire corner; and a corner guard member attached to said border wire at said corner, said corner guard positioned underneath said upholstery material for support and defining a smooth curved surface for contact with said upholstery material.
