Abstract

See full text

An adjustable height chair has a pair of side frames and a seat frame with two seat/backrest portions secured together, with the seat frame pivotably mounted in the side frames. The chair height is changed by rotating the side frames in a direction opposite to the rotation of the seat frame, so that a seat panel which previously served as a platform to sit on becomes a backrest, and vice-versa. The chair preferably has one or more crossbars to serve the double duty of strengthening the frame of the chair, and supporting the seat panels in both sitting positions of the chair.
