ABSTRACT:
A stacking chair and a metal chair frame therefor. One frame member has an U-shaped, horizontal portion and a pair of vertical front legs. The horizontal portion comprises a lateral rear portion and horizontal side portions that lie generally parallel to each other, but diverge somewhat from rear to front. Each of two flanged frame juncture members has a horizontal top and a pair of vertical side flanges; the top has a pair of horizontal edges and each side has a pair of vertical edges. One horizontal edge and two vertical edges of each are welded to the frame side portions adjacent the rear lateral portion. Rear legs with integral back-support portions are welded to the other horizontal and vertical edges, so that they are spaced apart from each other farther than are the front legs. The rear legs may be two separate members or there may be a single continuous member including both legs and joined at the top. A seat (preferably non-rigid, resilient) bridges and is secured to the frame side portions and urges them toward a truly parallel relationship, and a similar back bridges and is secured to the back-support portions and, if they diverge, urges them toward a truly parallel relationship.
