Abstract
A flexible chair includes a seat frame having a bidirectional fabric stretched over the seat frame to define seat back and seat bottom portions. The seat frame is supported on an upper axis and a lower axis by a flexible frame. In one embodiment, the flexible frame is a substantially continuous symmetrical loop defining arm portions. The arm portions are supported by a pair of u-shaped support forks. The connection geometry between the forks and the frame may be adjusted to provide varying degrees of flex from the chair frame. In another embodiment, the flexible frame is a pair of symmetrical loops including ground supporting portions.
