ABSTRACT:
Folding chairs have interlocking braces 27 and 28 that prevent relative movement between chairs in a stack. The braces have offset rear stops 30 and forward lugs 31. The braces are mounted to the sides of the legs such that they prevent sideways sliding movement of another chair stacked thereon and prevent lengthwise movement of chairs of like construction stacked thereon by the brace lugs of one chair striking the brace stops of the other.
