Abstract
A piece of furniture includes a rectangular frame for supporting a plurality of sinuous springs. A plurality of clip assemblies are secured to opposed side walls of the frame. Each clip assembly comprises a metallic clip having tabs for holding a plastic liner inside a curved portion of the clip assembly. Each clip assembly also has a detent which inhibits movement of the sinuous spring and has tacks for insertion into the frame. Flexible connectors may be located in grooves of the clip assembly to collate multiple clip assemblies.
