Do stairlifts work on curved stairs?
Yes. A stairlift will go around a bend. It is not the same product as the one for a straight flight.
A straight rail is cut to length. It only works if the stairs run in one line from bottom to top. Any turn, intermediate landing, fan of pie-shaped treads, or spiral means you need a curved rail. That rail is built to match the angles of your stairs. Stannah says it can fit those layouts as long as the curve can be measured. Our FAQ uses the same rule.
Need A Stairlift does not sell or install stairlifts. For $50 we ask companies that cover your ZIP to price the same stairs. On a curve, the useful comparison is several custom quotes, not one sales visit.
Straight vs curved is the rail
The chair looks similar. The rail does not.
Stannah's rail guide puts it this way: a straight rail is mass-produced and cut to length. A curved rail is custom-made so the chair stays level through the bends. They also split curved rails into two families. A custom rail is built for your stairs and usually hugs the turns tighter. A modular rail is assembled from prefabricated pieces and can arrive sooner. The ride is often less smooth on a tight spiral.
Bruno's 2026 cost page treats curved and spiral stairs as the more complex job. Length, number of turns, and how sharp the angles are all feed the price. They describe a high-end curved rail as handmade so it follows every angle and leaves more open space on the steps.
Savaria's Handicare 4000 is a twin-rail curved lift they custom fabricate. They say they can produce one in as little as two weeks, and they use a photo-measuring system so you can see the rail on your stairs before you buy. Their Freecurve is a single-tube custom rail for turns and pie-shaped stairs.
That is what those makers publish. It is not a scorecard.
What about a landing in the middle?
People sometimes ask if two cheaper straight lifts, one on each flight, would do.
Bruno's cost page says a continuous curved lift from top to bottom is the usual approach for stairs that hit a landing and then turn. Two straight lifts can cost less. You then have to get off one chair, cross the landing, and get on the other. That is a real option if transferring is easy for the rider. It is a different job than one rail that goes all the way.
If a quote is two straight units and another quote is one curved rail, you are not comparing the same thing.
The wait is usually the factory, not the afternoon of labor
A straight rail can often go in the same afternoon it arrives. Our FAQ says a few hours is common. Bruno puts straight indoor installs at 2 to 4 hours including delivery.
A curved rail has to be manufactured first. Bruno says a custom 400 lb curved order is typically several weeks from order to install, and install day itself commonly runs 4 to 8 hours. Savaria's "as little as 2 weeks" is fabrication time. It is not a promise that every dealer in every ZIP is that fast.
The company you pick will usually measure in person before a firm price. Photo-based quotes from us are estimates. That visit happens because you invited it. See how it works.
The rail still bolts to the treads, not the wall. Same as a straight lift. More on that in how to install a stairlift.
What to check on the quotes
- Same job: one continuous curved rail, or two straights with a transfer
- Wait time for the custom rail
- Options that matter on a curve, such as parking around a newel, a hinged rail at a doorway, or a powered swivel
- Who services it, and how far they are
- Price, and what it leaves out
A curve costs more than a straight run. Published ranges live in how much a stairlift costs. Do not treat a national brand's first number as the market. Some national brands quote $7,000 or more for a straight lift that a local installer prices for much less. The gap on a custom curve can be larger.
