A chair operable between an extended configuration and a collapsed configuration includes one or more legs, a handle and a locking mechanism. The one or more legs support a seat and the handle extends away from the seat opposite the one or more legs. The locking mechanism includes a lock plug disposed in an elongate trough. Movement of the handle between the extended and collapsed configurations involves depressing the lock plug and flipping the trough to an opposite side of the lock plug.

A foldable plastic-steel chair comprises a seat board assembly, a backrest, and a metal supporting frame. The seat board assembly and the backrest are connected to the metal supporting frame, and the seat board assembly comprises a seat board. The seat board comprises a surface plate and a surrounding edge connected to a periphery of the surface plate and extending downward, and the seat board is a vacuum-formed plastic board. The seat board assembly further comprises a metal frame abutting a periphery of seat board, and a bottom end of the metal frame is bent outward to form a hook. A lower end portion of the surrounding edge of the seat board is disposed in the hook, and a portion of the metal frame abuts an inner side of the surrounding edge. The hook is fixedly clamped to a lower edge of the surrounding edge.

A folding chair comprising a seat and a backrest carried by a folding structure, wherein the folding structure comprises a first structure defining a pair of front legs and a second structure defining a pair of rear legs, articulated to each other about a transverse axis by means of a pair of joints and movable relative to one another between an open position and a closed position, wherein the first structure comprises two first side elements and the second structure comprises two second side elements and wherein each of said joints comprises a first half-joint fixed to a respective first side element and a second half-joint fixed to a respective second side element, wherein the first and the second half-joints are rotatable relative to one another about said transverse axis, wherein the first structure comprises a pair of rods mounted within respective first side elements and movable between a raised position and a lowered position.

A seat board of a foldable chair includes a panel and a bottom frame. A top portion of the bottom frame is bent to form an annular inner blocking edge and an annular outer pressing edge, and an annular installation groove is formed between the annular inner blocking edge and the annular outer pressing edge. The panel form an annular folded-downward edge, and the annular folded-downward edge is inserted into the annular installation groove. The annular inner blocking edge cooperates with the annular outer pressing edge to clamp and secure the annular folded-downward edge. Two elongated sliding slots are symmetrically located on outer side edges of a right side and a left side of the bottom frame, and the two T-shaped rivets are slidably connected to the seat board and chair legs.
