Abstract: A back adjustment system for a chair having a frame that includes a top end and bottom end. The back adjustment system may further, include a chair back having a first end and a second end. The first end of the chair back may be mounted solely to the top end of the frame of the chair and also includes an adjusting means, which may be mounted at the bottom end of the frame. The adjusting means may allow for engagement between the bottom end of the frame and the second end of the chair back. The adjusting means may be adapted to telescopically engage between the bottom end of the frame and the second end of the chair back thereby solely moving the second end of the chair back from a retracted position to an extended position.
