Abstract
The collapsible armless chair comprises a pivotally connected seat frame and a back frame which also define the leg supports. An arcuate-shaped projecting portion at the bottom of the back frame provides stability for the chair. The projecting portion is also angled upwardly relative to the ground plane. The user may lean back in the chair until the front leg support leaves the ground and rotate the chair right or left without rising from the chair.
