A foot operated two tread cassette step unit for mounting on a vehicle comprises two treads 8, 9 pivotally mounted to the cassette carrier frame (2, fig 2) with link arms 5, 6 positioned so that when deployed they form a two tread stair and when closed they lie substantially on top of each other for closure into the cassette case. The treads are pushed out of carrier by a gas strut (10, fig 1). The treads are moved from the closed position to the deployed position by the action of a foot pedal 11 with an over-centre spring 12 that also incorporates a position to lock the step against a catch arm 18 in the deployed position.
