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 chair surface for folding chairs, where the main chair surface includes hemming and a seating area. The main chair surface is mounted to the chair surface support section by the hemming. The circumference of the seating area has a surrounding seam, and the seating area comprises the shapeable seat section and the backseat section. The space between the surrounding seam and the hemming is connected by a stretchy or stretchable element to create the mounting structure. This invention is a seating area that is shapeable to form a seat section and a backrest section. It contours to the hip and does not create any tightening sensation.
