ABSTRACT:
A furniture assembly, such as a metal box spring assembly, including slats defining support members for a plurality of coil springs. An aperture is formed in the metal support slat with an upset portion disposed about the periphery of the aperture and out of the plane of the support member and the tail of the coiled spring is inserted into the aperture and thereafter the upset portion is flattened toward the plane of the support member to force the periphery of the aperture into gripping engagement with the tail of the coil spring to retain the coil spring to the support member. The upset portion has a groove therein for receiving a radially extending support portion of the coil spring for receiving and positioning the radially extending support portion of the coil spring thereby positioning the entire spring.
