Abstract
A back portion for a chair has a back frame, the back frame having a lower portion adapted to extend across at least a major part of a lower region of a seated adult occupant's back, an upper portion vertically spaced from the lower portion and adapted to extend across at least a major part of an upper region of the occupant's back, and a relatively narrow interconnecting region between the upper portion and lower portion. The relatively narrow interconnecting region is resiliently flexible to provide a flexing movement in a rearward direction of the upper portion relative to the lower portion. A cover operatively connected to the back frame provides a supporting surface for the back of the seated occupant.
