Curved stairlifts
If the staircase bends, turns or runs around a landing, a curved stairlift normally uses a rail made to follow that particular route.

Why the price rises
The rail geometry must match the turns, inclines and landing positions. Some systems use bespoke manufactured rails; Acorn’s 180 uses modular sections. The proposed route and options affect both cost and the space left on the stairs.
See our price guide for source-linked supplier examples rather than an assumed fixed cost.
Parking and overrun
Ask where the chair and rail will be when not in use. On some stairs, continuing the rail around a corner can create a better parking point, but it adds rail and can affect the price.
Reconditioned curved lifts
A reconditioned chair or drive unit does not necessarily mean a reused curved rail. Ask every supplier exactly which parts are new and how the rail will be matched to the stairs.
