According to some embodiments, a folding chair comprises a first frame element, a second frame element, wherein the first frame element moves from a first position remote from the second frame element to a second position toward, adjacent to or against the second frame element, and a cradle comprising a guide member that guides the first frame element into the cradle.

A foldable chair includes a foldable frame and a reinforcing joint. The foldable frame includes a supporting frame and a seat frame pivotally connected with each other via the reinforcing joint, wherein the reinforcing joint includes a first joint member, a second joint member, and a connecting member connecting the second joint member with the first joint member. The first joint member, having an engaging cavity, is coupled at the seat frame. The second joint member is coupled at the supporting frame and is received at the engaging cavity to frictionally couple with the first joint member. The reinforcing joint serves as a supporting shaft to support between the supporting frame and the seat frame and serves as a rotatable shaft to enable the second joint member to be rotated at the first joint member for a pivotal movement between the supporting frame and the seat frame.

A chair backrest structure and a backrest chair having the chair backrest structure. The chair backrest structure includes a backrest plate and a fixed frame for supporting the backrest plate. At least an upper edge of the backrest plate is folded backward to form a fixed flange, and the fixed frame comprises an installation slot corresponding to the fixed flange. The backrest plate is a vacuum-formed plastic plate, and a surface of the fixed flange comprises one or more inverted protruding teeth formed by vacuum-forming or by molding. The fixed flange is disposed in the installation slot, and the one or more inverted protruding teeth are buckled to an edge of the installation slot to limit the fixed flange from being separated from the installation slot.

A portable chair may include a first front leg and a second front leg connected by a front sled and a first back leg and a second back leg connected by a back sled. The first front leg and the first back leg may be pivotally connected to a sliding pivot on an armrest, where the sliding pivot moves relative to the armrest to adjust the chair from an upright position to a reclined position. The seat assembly may include a fabric member that is attached secured to a seat frame by a plurality of fabric retention members. In some examples, the portable chair may include a fabric member is releasably connected to the seat frame and back frame and also extends from a forward rail of the seat frame to a top rail of the back frame.

Embodiments of the present inventive concept provide a chair and tabletop assembly including a foldable frame wherein the foldable frame includes an upper component including a tabletop panel wherein the upper component and the tabletop panel are adapted to facilitate the chair and tabletop assembly to exhibit one of a chair configuration, or a combined chair and table or desk configuration.

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.
