An article of furniture ( 10 ) includes a base having a front ( 14 ) and a rear ( 16 ) and a top ( 18 ) surface. A backrest assembly ( 20 ) has a front edge ( 22 ) and a rear edge ( 24 ) and is slideably arranged relative to the base ( 12 ) in a plane parallel to the top surface of the base to adjust a depth (D) of the base as measured between the front edge of the backrest assembly and the front of the base. Further it includes a locking mechanism having a displacement member ( 48 ) movably received in the housing ( 42 ), the displacement member being displaceable between a locking orientation and an unlocking orientation, when the displacement member is in its locking orientation the locking member ( 50 ) is urged partially out of the aperture ( 50 ) in the housing to protrude a predetermined extent through the housing to effect locking and, when the displacement member is in its unlocking orientation, the locking member is free to be at least partially withdrawn in the housing to effect unlocking. |
