TKE/Access BDD Flow X curved stairlift
Flow X uses a single rail and a seat that can turn while travelling. That changes how it negotiates bends and narrow spaces, so it is worth comparing the actual movement as well as the rail.

These figures are for the model or version named. They don't show whether it will fit your home, so a survey is still needed.
Swivelling during travel
Access calls the system Advanced Swivel and Levelling. Ask the dealer to demonstrate what the chair will do on the proposed staircase, including the narrowest point. The user may prefer to face a particular way, and there must be enough room for their knees and feet throughout the journey.
Narrow does not mean an automatic fit
The stated minimum is a starting point for a survey, not permission to order from a tape measurement. Door frames, handrails, radiator valves and the user’s posture may affect the available route. Ask the dealer to explain any changes needed to the stairs and whether people can still pass the parked lift comfortably.
Controls, belt and calling for help
The specification includes a folding joystick and a belt designed for one-handed fastening. Try both during a demonstration. A call device can contact stored numbers; ask what connection it needs and what works during a power failure. Do not assume it is a monitored emergency service.
Buying through a dealer
TKE/Access BDD directs buyers to local dealers. Ask which business is responsible for installation, warranty work and later servicing. We couldn't find a current model price, a warranty period that applies to every dealer, or a clear drawing showing the folded width. Compare Acorn 180, curved Siena and Handicare 4000 against the same staircase. Each has different movement, rail and capacity considerations; a single narrow-width figure is not enough to choose between them.
