Abstract

A spring module for a furniture cushion includes a conical spring and a double-layer flexible sleeve. The double layer flexible sleeve has a frustoconical first outer layer having a first closed top end, a first open bottom end, and a first outwardly extending flange at the first open bottom end. A frustoconical second inner layer inside the frustoconical first outer layer has a second closed top end, an open second bottom end, and a second outwardly extending flange at the open second bottom end of the frustoconical second inner layer. The conical spring is between the first outer layer and the second inner layer. The spring module may be attached to a base having locking structures for locking adjacent spring modules together.
