Abstract
A family of improved seat base assemblies for furniture seats and automotive seats and the like. A cushion base means, which might comprise a plurality of sinuous spring bands, a wire mesh unit, or chord rubber webbing or the like, is mounted between the front, back, and side nails of the seat frame. Rail connecting means connect at least the back rail to the cushion base means. The rail connecting means provides vertically resilient support to the cushion base means which increases as the cushion base means moves downwardly under load. In one form of the invention rail connecting means connect a wire mesh unit to all four of the rails, around its entire periphery.
