A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.

A camping stool includes a plurality of seat members and legs pivotally coupled to a pair of hub assemblies. Each hub assembly includes a plurality of tracks. A shaft extends between the pair of hub assemblies. The plurality of tracks extends along a length of each hub assembly and is aligned with the shaft. The plurality of seat members and legs are inserted into the plurality of tracks along a base portion. The plurality of seat members and the plurality of legs are pivotally coupled within the plurality of tracks through a rack and pinon gear system. The track defining a plane of rotation of the plurality of seat members and the plurality of legs.

A foldable chair frame and a foldable chair are provided. The foldable chair frame includes a base, having three or more opening grooves; and three or more joint structures, each including a first rotating member and a second rotating member that are coaxially pin-jointed in the opening groove. A stopper that limits a relative rotation angle between the second rotating member and the first rotating member is disposed on the first rotating member. A first abutting part that limits a relative rotation angle between the first rotating member and the base is disposed on the first rotating member; and/or a second abutting part that limits relative rotation angle between the second rotating member and the base is disposed on the second rotating member.
