Straight vs. Curved Stairlifts: What's the Difference — and Which One Do You Need?

You've decided a stairlift is the right solution — now someone's asking whether you need a "straight" or "curved" model, and you're not sure what that even means. It's a common point of confusion, and the answer is simpler than it sounds: it comes down to the shape of your staircase, not your preference. Here's what you need to know to figure out which type applies to your home.

What Is a Straight Stairlift?

A straight stairlift runs along a single, uninterrupted flight of stairs — no turns, no bends, no landings partway up. If your stairs go straight from the bottom to the top without changing direction, this is what you need.

Straight stairlifts are the most common type, and they're what most Massachusetts homes require. The rail is a standard length, cut to fit your staircase, and installation typically takes two to four hours. They're also available in new and certified refurbished models, which gives families more flexibility on cost.

We carry several straight stairlift models including the Bruno Elite, the Bruno Elan and refurbished Brooks and Acorn models. See our full lineup on the products page.

What Is a Curved Stairlift?

A curved stairlift is designed for staircases that change direction — a bend, an intermediate landing, an L-shape, a U-shape, or a spiral staircase. If your stairs don't go straight from bottom to top, a standard straight rail won't fit.

With a curved stairlift, the rail is custom-made to match the exact shape of your staircase. No two curved rails are alike. Each one is made to order based on precise measurements of your specific stairs. We primarily install the Bruno Elite Curve for indoor staircases and the Bruno Elite Outdoor Curve for exterior staircases.

Because the rail has to be manufactured, curved stairlifts take longer from assessment to installation than straight models. They're also not available refurbished. But for the right staircase, they're the correct solution — and they're built to last.

How to Tell Which One You Have

You can usually figure this out by walking your staircase:

• Does it go straight from bottom to top with no turns or landings? → You likely need a straight stairlift
• Does it curve gradually or make a turn at some point? → You likely need a curved stairlift
• Is it an L-shape or U-shape with a flat landing between two flights? → Read the next section before assuming you need a curved lift

If you're still not sure, that's exactly what our free in-home assessment is for.

The Option Most People Don't Know About: Two Straight Lifts

Here's something worth knowing if your staircase is L-shaped or U-shaped with a flat landing between two separate flights of stairs: you may not need a curved stairlift at all.

In many of these homes, we can install two straight stairlifts — one for each flight — and the user transfers on the landing between them. This approach can mean faster installation, lower overall cost, and the ability to use refurbished equipment on one or both lifts.

It's not the right solution for everyone. It requires the ability to stand up and sit down again on another chair. For someone with significant mobility limitations, a single curved lift that carries them the entire way may be more practical.

This is exactly the kind of conversation we have during a free in-home assessment. We look at the staircase, talk through the person's mobility needs, and give an honest recommendation — not just the most expensive option.

Which Option Is Right for You?

Here's a quick summary:

• Straight staircase with no turns → straight stairlift
• Curved or spiral staircase → curved stairlift
• L-shape or U-shape with a flat landing → curved stairlift or two straight lifts, depending on mobility

If you have a straight staircase and are weighing your options between purchasing and renting our guide on renting vs. buying is a good next read.
