A curved stairlift is not a stairlift with a bend in it. It is a rail manufactured for one staircase, and once it is in production almost nothing about it can be changed. That makes the decisions you take before ordering more consequential than on any other piece of equipment we fit.
What counts as curved
Any turn. A quarter turn, a half turn, a spiral, an intermediate landing, or a single winder step at the top. If the flight does not run in one unbroken straight line, the rail has to be made to follow it.
People push back on this, usually about the single winder. It is understandable and it does not change the answer. The rail follows the stairs, and if the stairs turn once, the rail turns once, and it has to be built that way.
Multi-landing staircases
A staircase with two landings and three runs is common in older two-storey houses and it is entirely doable. The rail runs continuously over every landing, so the user boards once at the bottom and gets off once at the top with no transfers in between.
That continuity is the whole argument for a curved rail over two or three straight lifts. Each transfer between lifts is a stand, a turn and a sit, performed on a landing, by somebody whose balance is already the reason you are reading this.
When two straight lifts genuinely are better
Where there is a generous landing, where the person walks reasonably well, and where budget is the binding constraint, two straight lifts can be the right call. They cost less, they go in faster, and each one is a stock rail.
We will tell you when that applies. We will also tell you when it does not, which is more often, because the landing is usually smaller than people remember and the transfer is harder than they imagine.
How the rail gets made
Harmar measures the Helix with a calibrated camera kit, which produces a digital model of the staircase rather than a set of tape measurements. Bruno builds the Elite Curve rail by hand in Wisconsin from surveyed dimensions. Both approaches produce a rail cut once, for one house.
Three to five weeks is the manufacturing window, and it is real. The install afterward is a single day. Anybody telling you a curved lift can be in next week is describing a straight one, and that is the most useful sentence in this article.
Decisions that must be made before production
- Which side. Driven by the person’s transfer, the handrail and the doorways at each end. It cannot be swapped afterward.
- Parking positions. Where the lift sits at the top and bottom. This decides whether it blocks a doorway for a decade.
- Capacity. The Bruno Elite Curve carries 400 lb, the Harmar Helix 350 lb. If the person is near either figure, that decides the model.
- Indoor or outdoor. An outdoor curved rail is a different build, not an indoor one with a cover.
- Powered swivel. On a tight top landing this is worth more than it costs.
What it costs and why
Substantially more than a straight lift, and almost all of the difference is the rail. The carriage, seat and controls are broadly comparable; the one-off manufactured rail is not. Our stairlift page explains the full set of factors without pretending a single number exists.
If you move
A curved rail was built for one staircase and rarely transfers usefully to another. Worth knowing before you buy if a move is a realistic prospect in the next few years. It also means a used curved lift is almost never the bargain it appears to be, for exactly the same reason.
Georgia, specifically
Stairlifts are state regulated here, through the Office of Insurance and Safety Fire Commissioner, which means licensed installation and inspection rather than a preference. We hold that licensing in our own name. It is a fair question to put to anybody quoting you.
Before you commit to anything
Send us a photograph from the bottom looking up and one from each landing. That is usually enough for us to tell you whether you are looking at a curved rail, two straight lifts, or something else entirely. Our curved stairlift and the straight stairlift pages cover both options, and all consultations, estimates and scopes of work are free of charge with no pressure or obligation.
And if what you actually need while you decide is a rollator, a transport chair or bathroom safety, those ship free from our online shop without any of this.
What the survey has to capture
On a curved job the survey is the product. Every riser height, every tread depth, the exact geometry at each turn, the position of the newel post, the width at the narrowest point, where the power is, and what is at the top and bottom that the lift must not block.
A tape measure and a sketch is not enough on a turn, which is why the measuring method matters. A quarter inch of error at the first turn compounds over the rail, and the rail is cut once.
What arrives on install day
Rail sections matched to the survey, in order, with the joints prepared. They go together in sequence, the joints are set and checked, and the carriage is commissioned across every turn rather than along a single run. It is a longer day than a straight install and it is still one day.
What it is not is a job that can be brought forward. The rail was in production for the previous three to five weeks.
Living with a curved lift
Day to day it is no different from a straight one. It parks at a charging point, it runs on batteries so it works through a power cut, and the seat folds against the rail so the stairs stay usable on foot. The turns are slower than the straight sections, deliberately, and that is normal rather than a fault.
