A seat comprising side uprights (110, 110'), a seat (120) and a back (130). It also includes a primary interlocking system (111, 111') to attach the side uprights in a roughly perpendicular fashion to the seat, a second interlocking system (122) to attach the seat in a roughly perpendicular fashion to the back, a wedge system (150) positioned between the back and the side uprights, and fasteners to lock the wedge system to the back and side uprights. Once the seat, uprights and back are interlocked, the whole assembly is held together by assembling the wedge system and fixing it in position using the fasteners. |
