A folding chair with multiple modes may include a first frame and a second frame rotatably connected by a joint assembly, a first support arranged in the first frame and a second support arranged in the second frame and six legs. The six legs may include a first pair of legs rotatably attached to the second frame, a second pair of legs rotatably attached to the first frame (e.g., via another joint assembly), and a third pair of legs rotatably attached to the second frame. The folding chair may further include a pair of armrests rotatably attached to the joint assembly. The multiple modes of the folding chair may include a first mode wherein the folding chair is configured as a dining chair, a second mode wherein the folding chair is configured as a lounging chair and a third mode wherein the folding chair is configured for compact storage.

A furniture assembly is provided that allows to independently adjust height of furniture legs and thus adjust the angle at which the user-interfacing surface of the furniture, such as seat or tabletop, are positioned. This feature allows to set up the furniture for office-type use even in the outdoors and to compensate for sloped or otherwise uneven terrain. The furniture assembly can take form a chair, a sofa, or a table, with all of these furniture items being easily and conveniently foldable and unfoldable to allow for easy transport. Multiple safety features promote the furniture in staying in folded or unfolded configuration, as desired by the user, and prevent accidental change of configuration.

A foldable origami-shaped furniture assembly includes floor panels including a first floor panel and a second floor panel. The first and second floor panels are pivotally moveable between a folded position and a deployed position. A table includes a first member and a second member. The first and second members are pivotally moveable between a folded position and a deployed position. A plurality of chairs, each chair is adapted to be in a folded state and in an expanded state. A cable that passes through the table and the chairs such that the cable is passively pulled when the first and second floor panels become coplanar and the first and second members become coplanar. Each chair is expanded with a front leg of the leg sliding along a channel for expanding the chair. A plurality of legs support the table in the deployed position.

An assemblage (10) is disclosed for assembling into a treatment chair for seating a subject undergoing a personal treatment, and subsequently disassembling for reassembly. The assemblage comprises a seat and backrest assembly (20), and a stand (assembly 50) for rotatably supporting the seat and backrest assembly. The seat and backrest assembly comprises a seat (21) and a (backrest 22), the seat comprising an upper side (23) on which the subject sits in use, and an underside (24) comprising a stand assembly mounting means (25) for releasably mounting the stand assembly. The backrest engages with the seat so as to be independently reclinable with respect to the seat, and is detachable from the seat and/or foldable onto the upper side of the seat so as to lie substantially flat therewith. The stand assembly comprises seat engagement means (51) for releasably engaging with the underside of the seat, hydraulic height adjustment (means 53) for hydraulically raising and lowering the height of the seat and backrest assembly in use, and legs (56) which are foldable between an extended position in which the legs extend laterally from the stand assembly to support the treatment chair in use, and a folded position in which they lie against or adjacent the hydraulic height adjustment means.

A folding crutch chair includes a pivot base unit and at least three support leg units. The pivot base unit has at least three mounting slots angularly spaced apart from one another about an axial line, and at least three pairs of joint portions respectively formed in the mounting slots. Each support leg unit includes a pivot seat, an outer tubular piece, and an inner tubular piece extending telescopically relative to the outer tubular piece. The pivot seat has a pair of pivot portions respectively and pivotably connected with the joint portions such that each support leg unit is rotatable relative to the pivot base unit. The support leg units are shiftable between a folded state and an unfolded state. The length of the support leg units is reduced when folded so as to facilitate packaging, storage and carrying.
