Abstract
A stairlift includes a rail cross-section and mounting rollers which, in combination, allow a stairlift assembly to be achieved which occupies little space and has a reduced visual impact. The rollers engage rolling surfaces arranged about the outer periphery of a tubular rail. The surfaces are preferably defined by structural components of the rail and are preferably non-parallel and non-perpendicular to the stair surfaces upon which the stairlift is mounted.
