A folding swivel chair support frame, which includes a seat frame and a chair leg frame; and the seat frame includes a U-shaped first support rod, a second support rod, and a cushion rod that are hinged to each other, and a foldable connection is formed by a turntable and a shaft rod that is locked on the first support rod. The seat frame is inserted into the guide tube of the chair leg frame by means of the shaft rod to form a docking position with the chair leg frame, and the turntable on the seat frame abuts against the support plate of the chair leg frame to from a rotatable load-bearing support.

A folding chair includes a lower assembly including a lower block and three or more legs pivotally connected to the lower block; an upper assembly including an upper block and three or more arms pivotally connected to the upper block; a middle assembly connecting the upper assembly and the lower assembly; and a flexible seat including the same number of end portions as the number of the arms, wherein each end portion is arranged at an end of each arm away from the upper block, wherein the upper block is provided with a stop portion to limit the rotation angle of the arms, and wherein the arms are retractable, the flexible seat is arranged to be in a relaxed state when the arms are in a retracted state, and in a tight state when the arms are in an extended state.

Woven inflatable devices and methods for making woven inflatable devices are provided. The woven inflatable devices include a laminated sheet with inflatable regions that when inflated cause the laminated sheet to transform from a planar shape to a three-dimensional shape such as a chair, container, or kiteboard harness.

A fan-equipped apparatus comprising an elongated fan plenum for a cooling chair is disclosed. In some embodiments, an elongated fan plenum can be configured to direct airflow through a chair back and concentrate on a user's back. In some embodiments, a chair with a fan-equipped cooling apparatus and a porous chair back is provided. In some embodiments, a fan-equipped apparatus can be attached to a chair selected by the user. Thermal imaging demonstrates cooling of a user by operation of the apparatus.

The present chair includes a scissoring straight leg and oblique support mechanism such that the chair may be folded between open and closed forms. The straight legs include lower feet and upper hubs. The oblique supports extend between the lower feet and upper hubs. The lower feet include structures that provide character to the folding chair.

A folding chair includes front and rear supports that fold and/or retract into central beams to reduce the space occupied by the chair in a folded configuration. A backrest is coupled to the central beams with a hub that allows an angle of the backrest relative to the central beams to be selected and for the backrest to be folded flat relative to the central beams. One or more actuators and pin actuators may control the relative movements of the backrest, front support, rear support, and central beams.
