There is disclosed a manually operable height adjustable platform (2) in which a platform (8) is mounted to a base (4) via an extensible scissor mechanism (12). At least one drive strut (30, 32, 34) is mounted in a force path between the platform and the base and configured to bias the platform and the base away from one another via extension of the scissor mechanism. An actuation system (36) controls movement of the platform and the base away from one another under the biasing force applied by the drive strut, where the actuation system has a manual actuator operatively connected to a pinion on one of the platform and scissor mechanism/base configured to a engage a rack on the other of the platform and scissor mechanism/base. There is also disclosed a manual actuator mounted above the platform for operating the actuation system by an operator in normal use, and an override mechanism mounted below the platform to act on the drive strut for lowering of the platform without actuation of the manual actuator. The override mechanism may be used in an emergency.
