A manually operable height adjustable platform has a platform mounted to a base via an extensible scissor mechanism. At least one drive strut 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 controls movement of the platform and the base away from one another under the biasing force, where the actuation system has a manual actuator operatively connected to a pinion on one of the platform and scissor mechanism/base configured to engage a rack on the other of the platform and scissor mechanism/base. A manual actuator mounted above the platform operates the actuation system by an operator in normal use, and an override mechanism mounted below the platform acts on the drive strut for lowering of the platform without actuation of the manual actuator.
