A portable chair includes a frame and a sling for accommodating a seated user. The frame includes an upper back pair of bars, a lower back pair of bars, a hub configured to couple the upper back pair of bars to the lower back pair of bars, a middle pair of bars configured to be coupled to a corresponding one of the lower back pair of bars, a front pair of bars configured to be coupled to a corresponding one of the middle pair of bars, and a front joint configured to couple the front pair of bars to each other.

The invention discloses a double folding chair with rotation angles. The double folding chair comprises four backrest pipes and two armrest pipes, wherein the a wrest pipes and the backrest pipes form a folding chair frame, rotation-angle transverse-bracing pipes are arranged between the two backrest pipes in the middle so that a flare angle can be formed between two chair backs, and intermediate connecting pieces which can rotate coaxially are arranged on a front support of the folding chair frame so as to be matched with the rotation-angle transverse-bracing pipes. Since the flare angle can be formed between two chair bodies, chair users can communicate conveniently, and the double folding chair has the advantages of being reasonable in structure, good in user experience etc.

A folding sofa that includes symmetrical armrest bars on both sides, front support bars and rear support bars, as well as a fabric seat. The armrest bar consists of a curved U-shaped bar with a symmetrical armrest section and U-shaped portion. The armrest section is formed in a wave shape that starts low in the front and rises high in the rear, with the front lower portion also being attached to an armrest auxiliary bar to provide support for resting the forearms. The rear support bars, after hinging to the armrest bars, have extended sections protruding forward to support the front edge of the fabric seat cushion.

A seat includes a frame defining an interior space bounded by an outer periphery. A fabric portion extends radially inward from the frame. A plurality of bands is engaged with the fabric portion and a plurality of support members is coupled to one or more bands of the plurality of bands. Each support member includes a connection member and a contact member secured to the connection member. The contact members cooperate to form a support surface spanning at least a portion of the interior space.

The assembly chair includes a pair of frames, a plurality of coupling rods, a plurality of pairs of depressed portions, at least one support member, and a sheet. The sheet is removably installed between the support member and the coupling rod. At least at one end portion of the sheet, the sheet includes a plurality of inserted portions along a width direction of the sheet. A flat plate is passed through at least one of the inserted portions. The support member with a flat intermediate portion is passed through another one of the inserted portions. The sheet is wound around outer peripheries of the inserted portion through which the plate is passed and the inserted portion through which the support member is passed to adjust a length of the sheet. In such state, the support member has both end portions fitted to the depressed portions on the frames.
