UK's Biggest Motability RetailerLast Updated: 16/10/2026
If climbing the stairs has started to feel tiring or unsteady, a stairlift can make moving between floors safe and comfortable again. The first decision most people face is choosing between a straight and a curved stairlift, and the answer comes down mainly to the shape of your staircase. This guide explains how each type works and how a free home survey helps you get the right fit for your home.

A straight stairlift suits a staircase that runs in a single, unbroken line from bottom to top. A curved stairlift suits stairs that turn a corner or pass a half-landing partway up. If you can stand at the bottom and see the top step in one line, a straight model is usually the right starting point, but if the stairs change direction at any point, you will almost always need a curved rail.
The shape of the staircase is only part of the picture, though. Nearby doors and radiators can affect the fit, as can the needs of the person using the lift, which is why a home survey is the most reliable way to confirm the best option.
A straight stairlift runs on a rail cut to the length of one continuous flight. Because the rail doesn't need to bend, it can usually be supplied quickly and fitted in a few hours. Most models have a seat and footrest that fold up when not in use, leaving room for others to use the stairs.
Straight models are typically the more affordable choice, so if your staircase allows for one, it's often the most practical route. All of our stairlift options, including straight models, are covered on our stairlifts page.
A straight stairlift is usually suitable when there is one direct flight with no turns and enough width for the lift and other household members to pass. Your surveyor will also check the headroom, along with the space at the top and bottom for getting on and off safely.
If a door or busy hallway sits close to the bottom step, a hinged rail can fold the lower section out of the way when the lift isn't in use. This keeps the hallway clear without ruling out a straight model.
A curved stairlift follows a staircase that changes direction, such as stairs with a 90 or 180 degree turn, an intermediate landing, fan-shaped winder steps, or several connected flights. Since no two curved staircases are the same, the rail is made to measure for your home, allowing the lift to travel around bends and across landings in one smooth journey.
Our stairlift specialists can talk you through the curved options available and how they handle more complex layouts during your home survey.
You'll generally need a curved model when the route passes at least one corner or landing. A curved rail can also be designed to park the chair in a particular position at the top or bottom, which helps if space for getting on and off is tight or the user needs a safer transfer point.
Because the rail is bespoke, curved stairlifts take longer to manufacture and cost more than straight models. For homes with a turning staircase, though, they remove the need to stand up and change chairs partway up, which matters a great deal for anyone with limited strength or balance.
| Feature | Straight stairlift | Curved stairlift |
|---|---|---|
| Staircase type | One straight flight | Bends, corners, landings, or winders |
| Rail | Standard rail cut to length | Made to measure for your stairs |
| Lead time | Usually quick to supply | Longer, as the rail is manufactured for you |
| Installation | Often a few hours | Usually completed within a day |
| Cost | Generally lower | Generally higher due to the bespoke rail |
Some homes have two straight flights separated by a landing, and fitting two straight lifts can look like a cheaper alternative. It's possible in some cases, but it means getting off one chair and crossing the landing on foot before sitting down on the second. For someone whose balance or confidence is already reduced, that extra transfer adds risk at the very point a stairlift is meant to remove it.
Mobility needs can also change over time. A single curved lift provides one continuous journey and tends to be the more sensible long-term option, so it's worth weighing safety and comfort alongside the upfront price.
Once you know which type your staircase calls for, a few practical details help shape the final recommendation.
The stairlift needs enough room to travel safely, and other people in the home still need to use the stairs. A folding seat and footrest help, but the surveyor will check clearance along the whole route.
There needs to be a safe transfer area at each end of the staircase. A swivel seat, which turns the chair to face the landing at the top, makes getting off much easier and is worth asking about.
Radiators, windowsills, banisters, and doorways can all affect where the rail runs. Most of these can be worked around, but they need to be measured properly, and our stairlift measurement guide explains what to look at before your survey.
Think about how the user's mobility might change over the next few years. Choosing a lift with the right seating and parking position now can save having to adapt it later.
Photos and your own tape measurements can only tell a stairlift specialist so much about your home. During a free home survey, an Eden Mobility specialist looks at the shape and dimensions of your staircase along with any obstacles on the route. They'll also talk with the person who will use the lift about how they get on and off, and which features would make day-to-day use easier.
You'll then receive a clear recommendation and a no-obligation quote based on your home. If you decide to go ahead, our guide to stairlift installation and how to prepare your home walks you through what happens on fitting day, and you can read more about the benefits of installing a stairlift if you're still weighing things up.
A straight stairlift only travels along one uninterrupted flight, so if your stairs turn at any point, a curved model will normally be needed.
In most cases they are, because the rail is made specifically for your staircase. The final price depends on the layout of your stairs and the features you choose.
Many straight stairlifts are fitted in a few hours. Curved installations take longer but are commonly finished within a day, and your timescale will be confirmed before fitting.
Stairlift rails are normally fixed to the stair treads rather than the wall, so structural work is rarely needed. Your surveyor will explain how the rail will be secured.
Many stairlifts suit narrower staircases because they fold away neatly. The available width and safe clearance both need checking during the survey.
A home survey is designed to answer exactly this question. A specialist will assess your stairs and recommend the most suitable option, with no pressure to commit.
Choosing between a straight and curved stairlift starts with your staircase, but the best choice is the one that works safely and comfortably for the person using it every day. Explore our full range of Eden Mobility stairlifts or book a free home survey to get started.
