The present invention enhances the safety of a stairlift by providing a proximity sensor ( 40, 42 ) to detect the proximity of users and other objects to a stairlift carriage ( 20 ) and to render remote call controls ( 22, 24 ) inoperative. A chair occupancy sensor may also be provided to prevent inadvertent operation of the main user control ( 38 ) when a user is mounting, or dismounting from, the stairlift.
