A folding chair includes two standing posts, two diagonal bracing mechanisms, and a linkage mechanism, where the linkage mechanism includes two linkage posts that are crossed and hinged with each other. The diagonal bracing mechanisms each include two diagonal braces, two under-frame posts, a first connector, and a second connector. The upper ends of the two diagonal braces and an upper end of one linkage post are hinged with the first connector, and the lower ends of the two diagonal braces are respectively hinged with the first ends of the two under-frame posts. The second ends of the two under-frame posts and the lower end of the linkage post are hinged with the second connector. The two standing posts are respectively connected to two first connectors and respectively limit the positions of the two first connectors.

Foldable chair comprising a seat (10) and at least three legs (11) attached to the seat (10). A leg holder (12) which is arranged spaced apart from the seat (10) is associated with each leg (11) and each leg holder (12) has a connecting element. The legs are received at a mounting (13) by means of the connecting elements so as to be movable relative to one another. The leg holders (12) have as the connecting element a formed-on part, said formed-on parts (12a) being rotatably mounted between the legs (11) and thus a easy to produce, foldable chair is provided, which may take up high forces in the connecting means between the legs with minimal material wear.

A modular chair including a support portion to allow the support of a user on it and including a frame and a fabric. The fabric defines a surface suitable to support the user and a perimetral area defined by the edges of the surface. The frame defines, in use, a closed profile and is suitable to support the fabric in tension along at least part of the perimetral area, and comprises at least two parts separate and reciprocally loosely connected by two hinges arranged respectively at the ends of said parts to define a configuration of use in which the parts form the frame and a configuration of rest in which the parts are folded together. The hinges define two respective axes of rotation mutually aligned. The frame tensions the fabric only when the parts are in the configuration of use.

An adjustable chair may include a frame, a seat pan, a backrest, a pair of arm rests, at least two legs each comprising an inner leg configured to telescope out of an outer leg, and a leg locking system for locking the outer leg to the inner leg.

A compact collapsible camping chair includes upper tubes, leg tubes, a molded central tube connector and a seat back. The tube connector is molded from aluminum, zinc or plastic reinforced with glass fiber. Lower ends of the upper tubes fit snugly into circular upper holes in the central tube connector, and upper ends of the leg tubes fit snugly into circular lower holes in the central tube connector. Upper ends of the upper tubes fit into tube receptacles in the seat back. The two longer upper tubes are bent, whereas the two shorter upper tubes are straight. Elastic cords pass from the upper tubes, through the tube connector and into the leg tubes and tend to pull the tubes into the holes in central tube connector. The upper tubes, leg tubes, central tube connector and seat back can be placed in a bag that is less than one foot long.
