Abstract
A chair includes a base having a control assembly operably supporting a seat assembly and also a back assembly for movement about a seat tilt axis and a back tilt axis, respectively. The back assembly includes a flexible sheet supported at upper/outer corners by a back support structure and hanging downwardly. The flexible sheet includes a lower portion coupled to the back support structure by a tensioner for holding the lower portion rearwardly. A vertically-adjustable lumbar mechanism is adjustably supported on the back support structure and operably engages the flexible sheet for biasing an intermediate portion of the flexible sheet forwardly to both form the intermediate portion into a forwardly convex shape for postural lumbar support and also to tension the flexible sheet.
