Standard stairlifts
Rated for users up to 19 stone (120kg). Suitable for the vast majority of Salford customers and available new or reconditioned.
Heavy-duty models
Rated for users up to 25 stone (160kg). Reinforced seat frame, stronger motor and wider footplate.
Bariatric models
Rated for users up to 35 stone (220kg). Wider seat, stronger rail mounts, extended footplate. New only.
Why it matters
Using a stairlift above its rated weight voids the warranty and increases motor wear. Always be honest at survey — the price difference is small.
