Abstract: A combination stiffener and ganger bracket is designed for a stackable chair of the type having a generally horizontal seating surface and four downwardly extending legs. The bracket has a generally planar body with an attachment tab at both of its ends. Two edges of the bracket extend between the ends of the bracket. A hook member extends from one of the edges while an engagement tab extends from the other edge. A stacking tab projects from the plane of the body.

Abstract: A chair which includes a seat frame having depending leg members and a pair of upstanding, spaced apart members arranged to provide a lower backrest part for the chair and an upper backrest frame part having a pair of spaced apart depending members in registry with the upstanding members, said members being hollow with open extremities, and flexible spring means secured between each pair of members to provide an articulated, flexible spring backrest for the chair. Each flexible spring means includes an elongated, flat or blade spring member having its opposite ends secured within a holder member which is closed at one end and open at its opposite end for inserting the spring into the holder. The open ends of each holder have stop flange formations protruding outwardly thereon which, when the holders are spaced apart at their open ends with a slight gap therebetween, effect limitation of the angle of flexure of the spring by engagement of the flanges one with the other.
