The invention relates to a portable chair (1) having two front chair legs (2, 3), two rear chair legs (4, 5), two front chair arms (6, 7), two rear chair arms (8, 9), and two connection elements which are connected via a connection rod. The front chair legs and the rear chair legs each have a free end (2a, 3a, 4a, 5a) which is oriented towards an underlying surface (10), and the front chair arms and rear chair arms each have a free end (8c, 9c) which is oriented towards a seat surface (11) that is defined or can be defined by free ends (6a, 7a) of the front chair arms and free ends of the rear chair arms (8, 9).

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 portable adjustable chair is disclosed comprising a seating area for receiving a person having a front portion and a back portion. A front support connected to the front portion of the seating area for supporting the front portion of the seating area is also provided and a back support connected to the back portion of the seating area for supporting the back portion of the seating area. The chair also has a fulcrum member allowing movement of the back support and removing support for the back portion of the seating area provided by the back support while allowing the front support to support the front portion of the seating area and a support member connected to the seating area to support the back portion of the seating area when the back support is not supporting the back portion of the seating area.

A support device for supporting at least one person located on it includes a stiff frame, which comprises a plurality of structural elements and a plurality of supporting elements. Securing means are provided for securing the stiff frame to roof bars of a motor vehicle. A plurality of rotatable arms is provided, each of which is hinged in a specific supporting element and is rotatable from a rest position into an operating position, and vice versa. Locking means are provided for locking the rotatable arms in an operating position. A cloth, on which said at least one person can be supported has connecting means by which it is connectable to the rotatable arms. The direction of longitudinal extension of each supporting element is not parallel to the longitudinal axis of the stiff frame and each rotatable arm is made of two portions inclined with respect 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.
