Abstract

A rotatable chair back includes a lower section attachable to a chair seat, a flexible Y-shaped upper section for supporting a chair back frame, and two rigid supports extending substantially vertically into and between the upper section and the lower section. In use, the substantially vertical supports each serve as an axis of rotation about which the upper section may rotate relative to the lower section.
