Straight vs Curved Stairlifts
Choosing between a straight and curved stairlift is not simply a matter of preference. The layout of your staircase determines which type of stairlift will fit your home.
A single, uninterrupted flight will actually suit the Acorn 130 Straight Stairlift. Stairs with bends, turns, or intermediate landings may require the Acorn 180 Curved Stairlift. A free, no-obligation home survey can confirm which configuration is right for your staircase.

What is a straight Stairlift?
A straight stairlift, such as the Acorn 130, is designed for a single, uninterrupted flight of stairs. If your staircase runs from the bottom floor to the top floor without any intermediate landings, bends, or turns, this is the solution for you.
- Key Benefits: Straight stairlifts use a straight rail and are generally quicker and simpler to install. The Acorn 130 fits directly to the staircase rather than the wall, so no major structural changes are required.
- Specifications: The Acorn 130 features a weight capacity of up to 127 kg. It is a streamlined, efficient solution for those with a straightforward 2-story home layout or a simple basement-to-main-floor transition.
What is a curved Stairlift?
A curved stairlift, such as the Acorn 180, is designed for staircases with bends, turns, curves, or intermediate landings.
Key Benefits: The Acorn 180 uses Acorn's modular FastTrack® rail system, which is configured to follow the shape of your staircase. The rail is fitted directly to the stairs and can accommodate bends, turns, and landings.Specifications: The Acorn 180 is custom-built to your home’s unique dimensions
How do I know if my Staircase is straight or curved?
Determining your staircase type is usually simple. Take a look at this checklist:
- Does your staircase have any bends, turns, or intermediate landings?
- Is it a standard, single, uninterrupted flight of stairs?
If you answered “Yes” to the first question, you likely have a curved staircase. If you answered “Yes” to the second, you have a straight staircase. Intermediate landings can be a common source of confusion. If the stairlift needs to travel around a landing or change direction, a curved rail will usually be required. To be 100% sure, we recommend a free home survey, where our expert will measure your staircase to confirm the exact configuration.
Cost Comparison: Straight vs. Curved
Transparency is key when budgeting for home modifications.
- Straight Stairlifts: Straight rails are simpler to configure, so a straight stairlift will generally cost less than a curved model.
- Curved Stairlifts: Curved stairlifts generally cost more because the rail must be configured to follow the bends, turns, and landings of the individual staircase.

Installation Time: Straight vs. Curved
- Straight: A straight stairlift is generally the simpler installation because the rail follows a single uninterrupted flight. Installation itself can usually be completed within a few hours.
- Curved: A curved staircase requires a more detailed survey so the FastTrack® rail can be configured around bends and landings. Acorn's modular rail system avoids the lengthy factory-built rail process used by traditional curved systems, allowing curved stairlifts to be installed quickly once the correct configuration has been confirmed.
FAQs
- Can a curved stairlift be fitted to any staircase?
Acorn's modular curved rail system can accommodate many staircase layouts, including bends, turns, and intermediate landings. A home survey will confirm whether the Acorn 180 is suitable for your staircase.
- How long does a curved stairlift take to install?
While the actual on-site installation is efficient and tidy, the overall process takes longer than a straight lift because the rail must be custom-manufactured to your home’s exact dimensions after the survey.
- Is a straight stairlift cheaper than a curved one?
Generally, yes. Straight Stairlifts use a simpler rail configuration, while curved stairlifts require a staircase-specific FastTrack® rail layout.
- What is the Acorn 180?
The Acorn 180 is Acorn's curved stairlift, using a modular FastTrack® rail system designed to navigate bends, turns, and landings comfortably and reliably.
