Stairlifts for spiral stairs
A stairlift on a spiral staircase is possible in some homes: the stairs need to be wide enough and the spiral gentle enough for a curved rail. Tight spirals usually need a different answer.

What decides it
- Width: spiral stairs are often narrow at the inside; the rail usually goes on the outside, where the treads are deepest.
- Steepness at the rail: the tighter the spiral, the steeper the rail; curved stairlifts have a maximum angle (for example 56° for the Handicare 4000).
- Headroom: the rider passes under the turn above.
- Landing space at the top for the chair to swivel.
