Abstract: A pantographic support control mechanism (10) for use with furniture includes one or more pantographic linkages (16). The or each linkage (16) is mounted between a forward end (104) and a rearward end (26, 106). Extension of the linkage(s) (16) causes relative movement of the forward and rearward ends (104) (26, 106) away from each other whereas contraction of the linkage(s) (16) causes relative movement of the forward and rearward ends (104) (26, 106) towards each other. One or more support means (14) are pivotally mounted with respect to and at or near respectively one or more of the pantographic linkages (16). One or more corresponding urging means (12) are arranged to act between a pantographic linkage (16) and a respective support means (14) in a manner such that extension of the or each linkage (16) causes the or each urging means (12) to respectively act on its respective support means (14) to cause it to pivot from an inoperative position to an operative position.
