Abstract
A flexible chair frame includes symmetrical sides having at least a first crossbar affixed between the rear portions of the sides at seat level. The seat bottom portion of each side is angled upwardly near its end and includes a stacking insert with a tab extending therefrom and a second crossbar coupled between respective stacking inserts. A third crossbar is coupled between the rear portions and may include an arm portion. The chairs may be stacked such that the first crossbar of one chair rests on the stacking inserts of the chair below, regardless of whether arm portions are included on the third crossbar.

A chair frame, comprising:
- a pair of support legs one at each side, each support leg comprising a contiguous arrangement beginning with a resilient back leg portion oriented substantially vertically, then to a bottom leg portion extending horizontally along a floor surface, then to a front leg portion extending upwardly from the bottom leg portion, and then to a seat bottom portion extending rearwardly then turning upwardly at an acute angle to an end thereof;
- a first crossbar coupled between the ends of the seat bottom portions;
- a pair of stacking inserts coupled proximate to the ends of the seat bottom portions, each stacking insert having a tab extending forwardly therefrom;
- a second crossbar coupled between the back leg portions at a location which is below but proximate to the stacking inserts;
- and
- a third crossbar coupled between the ends of the back leg portions.
A high density stack of chairs, comprising a plurality of first chairs stacked in random order with a plurality of second chairs in nested overlapping relation, wherein each first chair and each second chair are substantially identical except that each first chair is an armchair and each second chair is a non-arm chair, and wherein the distance between adjacent chairs in the stack is substantially the same.
A chair, comprising:
- a frame having symmetrically disposed side frame members, each side frame member having a back leg portion oriented substantially vertical and contiguous with a bottom leg portion oriented substantially horizontal and contiguous with a front leg portion oriented substantially vertical and contiguous with a seat bottom portion oriented substantially horizontal,
- a seat having a front and a rear and coupled to the seat bottom portions of the frame such that the seat bottoms portions extend beyond the rear of the seat,
- a back having an upper back portion coupled to the back leg portions of the frame and a lower back portion coupled to the seat bottom portions of the frame which extend beyond the rear of the seat, and
- a pair of stacking tabs extending forwardly from the frame just above the rear of the seat.
