The Bison 50 stairlift is unrivalled in its choice of options to suit a variety of individual needs and circumstances.

The Bison 50 is a deluxe stairlift with many optional extras to suit most applications for straight stairs. This stairlift provides a very even, smooth and comfortable ride quality with a built in soft start and stop facility. The integral high power re-chargeable battery back ensures the stairlift is always available for use even in the event of a mains power failure.

The slim line design of the Bison 50 ensures it will fit on even the narrowest of straight stairs, folding up to less then 12 inches (297mm) when not in use.
