Particularly preferred collapsible chairs have a minimum configuration in which the back and front rods in a quad arrangement are extended to support the arm rests, the backrest, and the seat, and wherein the back and front rods are angled such that the backrest width to seat height has a ratio of between 1.4 to 1.8. Such chairs are not only esthetically pleasing, but also relatively comfortable for users of average and above-average height.
