ABSTRACT:
A spring module for a mattress box spring is formed of a stiffening element made of a sinuously-shaped spring wire and an attachment clip for attaching the spring module to a frame of a box spring, the length of wire being resiliently bent into a circular form and held in the circular form by opposite end portions of the length of wire being engaged with the attachement spring clip. In accordance with the preferred embodiment, the attachment clip is formed of a plate having a pair of notches at opposite lateral sides thereof that receive a respective end portion of each of opposite ends of the circularly bent length of wire with the plate passing through terminal undulations of the sinuous shape located at these opposite end portions. Furthermore, for enabling the plate to grasp respective wires of a wire frame of a mattress box spring, each of opposite longitudinal ends of the plate is provided with a central offset tongue. A box spring incorporating the spring module utilizes at least one spring module in conjunction with a multiplicity of coil springs of a lesser stiffness, the coil springs and the modules extending between upper and lower frames of the box spring.
