Abstract

Abstract A seat, such as an upholstered chair, sofa or love seat, is so constructed that it can be shipped in a flat package, knocked down, and assembled by the purchaser in a very few minutes. The seat has a back, two arms and seat which are assembled by connecting the back to the seat and then by ingenious means connecting the two arms to the back and seat. The upper ends of the arms have hook engagement with cooperating means on the edges of the back, whereupon the seat is bolted to the arms to complete the assembly. The seat construction employs conventional sinuous springs extending from front to back and the seat deck construction is such that longer springs may be used, connected in close proximity to the front and back of the seat deck and at relatively low points to improve the comfort of the seat by spring action. Tension means connected to the springs prevents the ''''bucketing'''' of the springs, the tensioning means being variable to control such action.
