A platform support system comprising a support pawl and an actuation system operable in response to an input received from a user to move the support pawl between a supporting position and a non-supporting position when the support pawl is not in use supporting a platform, wherein a platform is arrangeable with the support pawl so as to be supported by the support pawl when in the supporting position, and wherein operation of the actuation system in response to a user input leaves the support pawl in a supporting position when the support pawl is in use supporting a platform. The support pawl may also be mounted to enable a platform to move past the support pawl in a first direction by displacing the support pawl from a supporting position, the support pawl mounted to inhibit movement of the platform past the support pawl in a second direction when the support pawl is arranged in a supporting position.
