Abstract: A workstation system (1) comprising with a plurality of desktops e.g. (3a), each desktop (3a) comprising a primary work area (33) and at least one recessed portion e.g. (34b) providing an auxiliary work area e.g. (36b). The recessed portions (34b) of adjacent desktops (3a-3d) can be arranged to provide an interactive work area (6a-6d) for multiple people.

Abstract: A back portion for a chair includes a peripheral frame defining an opening therein. A lumbar support portion is disposed in the opening. The lumbar support portion comprises a substantially rigid panel. Two hinge devices are hingedly mounted on opposite sides of the peripheral frame. The lumbar support portion is mounted on the peripheral frame by the two hinge devices. Each hinge device has a biasing device associated with it to bias the hinge devices forwardly relative to the peripheral frame. A cushion may be mounted atop the lumbar support portion. The cushion has a first substantially planar sheet of resiliently flexible material and a second substantially planar sheet of resiliently flexible material. The first and second sheets are separated by a plurality of spaced webs of resiliently flexible material.

Abstract: A back portion (16) for a chair (10) includes a peripheral frame (34) defining an opening therein. A lumbar support portion (36) is disposed in the opening. The lumbar support portion (36) comprises a substantially rigid panel (207). Two hinge devices (214) are hingedly mounted on opposite sides of the peripheral frame (34). The lumbar support portion (207) is mounted on the peripheral frame by the two hinge devices (214). Each hinge device has a biasing device (226) associated with it to bias the hinge devices (214) forwardly relative to the peripheral frame (34). A cushion (540) may be mounted atop the lumbar support portion (207). The cushion has a first substantially planar sheet (542) of resiliently flexible material and a second substantially planar sheet (544) of resiliently flexible material. The first and second sheets are separated by a plurality of spaced webs (546) of resiliently flexible material.

Abstract: A castored base (18) for an office chair includes a plurality of radially extending legs (300), each leg having a socket or sleeve (308) fixed thereto adjacent an outer end thereof. A castor (302/402) is connected to each socket or sleeve (308), each castor having two wheel portions (312/412) and an axle assembly (316/404). The axle assembly includes an axle (314/414) to which the two wheel portions are rotatably mounted in spaced disposition and including a pin (318/418), wherein the pin (318/418) of each castor is received in a respective socket or sleeve (308) which extends at least in part between the two wheel portions (312/412). Only a small clearance is required between the underside of the legs (300) and the tops of the castors (302/402). Further, low profile legs (300) may be used in the base (18), while still providing the required strength and stability.
