ABSTRACT:
A spring support for a piece of furniture. The support includes a plastic sheet comprising a plurality of spaced apart ribs integrally joined together. The sheet includes a downwardly bowed portion joined by a first intermediate section to a front leg and joined by a second intermediate section to a rear leg. The legs are attachable to a furniture frame. The sheet varies in thickness with the minimum thickness occurring at the first and second intermediate sections located respectively adjacent the front and rear legs. The varying thickness and cross sectional area of the sheet provides for minimum deflection at the center portion of the sheet when downward force is applied thereto while maximum deflection occurs at the first and second intermediate section.
