Abstract
A one piece integrally formed moulded plastic chair (11) is disclosed having a seat (2), backrest (3) and legs (4-7). A U-shaped rib (19) extends between the upper regions of the rear legs (6, 7) to cross-brace same. A gap (24) is proved between the cross piece (20) of the rib (19) and the underside of the seat (2). In use the seat (2) deforms to reduce the size of the gap (24) under the weight of a sitter. This deformation thereby provides a more comfortable seat.
