A seating support device of a wearable chair includes a femoral link extending in a direction where a femoral region extends and configured to be connected with the femoral region, a crural link extending in a direction where a crural region extends, and configured to be connected with the crural region, and including a housing that is coupled at an upper end thereof to a lower end of the femoral link to be rotatable relative thereto and a sliding part that is slidably coupled to the housing in a direction in which the housing extends, and a limiting device operated in conjunction with a relative rotation between the femoral link and the crural link to allow the sliding part to slide vertically and to prevent sliding between the sliding part and the housing in a state where an angle between the femoral link and the crural link is a seating angle.

Embodiments of chair systems incorporating trekking poles include a low-back design employing fixed-length trekking poles, and a high-back design employing adjustable-length trekking poles that allow for adjusting the recline angle of the chair. The chair system generally includes a tubular frame that releasably engages a flexible seat. The tubular frame includes a front hub and a rear hub spaced one from the other by a cross bar, plus front and rear footings which stabilize the chair system on the ground or undersurface. A V-shaped upper support extending from the front hub supports and holds open the leg portion of the flexible seat, while the trekking poles are releasably engaged with and extend upwardly from the rear hub to support, and hold open and upright the back portion of the flexible seat.

A folding seat support frame includes an upper support frame detachably connected to a seat fabric and a lower support frame connected to the upper support frame, where the upper support frame includes an upper connector, short rods rotationally connected to the upper connector at a first limited angle, and upper connecting rods rotationally connected to the short rods at a second limited angle; the lower support frame includes a lower connector and lower connecting rods rotationally connected to the lower connector at a third limited angle; the lower connector and the upper connector are coaxially and rotationally connected; when the folding seat support frame is in an unfolded state, the lower connecting rods and the short rods are oriented to a side of the lower connector; when the folding seat support frame is in a folded state, the short rods are butted against the lower connector.

A quick-release device is for securing a rod of any gas cylinder into the plate of any chair, item of furniture, or other device supported by a gas cylinder and activating the rod with a button thereon. This universal quick-release device includes a sleeve in in the seat plate, an adapter fit into the sleeve, the adapter including an upper portion and a lower portion with different inner and outer diameters. The sleeve is configured to receive the lower portion of the adapter in a press-fit engagement. The upper portion is configured to receive the rod of the gas cylinder in a removable engagement.
