An articulated support chair has a frame, a seat cantilevered from the frame, and a back hanging from the frame, with a lower end of the back hinged to an underside of the seat. A lumbar support extends from the seat and pivots to maintain supporting contact as the angles of the seat and back change under varying load conditions. In further embodiments, arm rests may be rigidly coupled below the seat to the back, and a fold-down tablet may be affixed to the frame at one side of the seat. Wedge units assemble in a modular fashion to define straight or different curved or bent rows for waiting room, conference room, or auditorium/theater installations and provide side tables, lockable cabinets, or utility and light bays between adjacent seats. A task chair, a side chair, and tandem chair embodiments are described. |
