Abstract
Abstract The present invention discloses a chair having a seat (2) and a backrest (3) which is hinged to the seat (2) by a resilient hinge (7). The hinge (7) is substantially moulded together with the shell (1) formed by the seat (2) and backrest (3). The degree of flexure of the backrest (3) exceeds any flexure of prior art. One piece plastic shells and stops are preferably provided to limit the degree of flexure of the hinge (7). Moulding the hinge (7) with the shell (1) substantially reduces costs.
