Straight Vs. Curved Stair Lift – Which is right for you?

If you are considering purchasing a stair lift, you have likely come across different manufacturers and a variety of types and features available for stair lift systems. So many options can be a little overwhelming and even stressful, especially if you are early in your search and still trying to figure out what type of stair lift is right for you. Or you may not be sure a stair lift is an appropriate solution at all due to the uniqueness of your stairs.

The good news is, there is most likely a system that will work for you even if your stairs are long, deep, or narrow. Or if your stairs curve or spiral, there are solutions for that as well.

This article will discuss the two main options for stair lifts in your home, when one alternative is superior over the other, the installation process, and some of the features that make them unique. We’ll also share some of our straight and curved stair lifts with you.

If you still have questions, give us a call. We’d be glad to answer any questions or help you find a dealer in your local area.

Straight Stair Lifts

Straight stair lifts are the most common stair lift and are perfect for homes with traditional stairs with an average rise and run pattern. As a result of needing less customization, straight stair lifts are also less expensive than a curved stair lift.

These stair lifts use a straight rail that moves parallel to the stairs and can be mounted on either side of the stairs. Their design is best suited for a staircase with no bends, turns, spiral landings, or irregularities.

Sounds simple enough, right?

Straight stair lifts do not require any construction to your home and are mounted directly to your stairs (not the wall). The underside of the rail has brackets secured to the stairs, and the footrest and seat are mounted on the outside chassis, which slides on the rail.

The installation of a straight stair lift adds great accessibility without being invasive in your home. In most cases, an indoor straight lift can be installed by a professional in only two to three hours.

Straight stair lifts are great solutions for most people, but what do you do when you can’t use a straight stair lift?


Curved Stair Lifts

Curved stair lifts are better solutions for homes that contain stairs that change directions, curve, or have transitional landings. They are also great for homes with multiple floors. For instance, if you have a downstairs basement and an upper level.

Curved stair lifts are custom built and unique to your home. As a result of the custom configuration, curved stair lifts are usually more expensive than straight stair lifts.

Although curved stair lifts are more complex than your standard straight lift, installation is still easy and will generally take two professional installers about 3 hours to fully install. However, the installation time is dependent on the complexity of your configuration. Like straight stair lifts, supports are mounted to the stairs that safely and securely support the rails.

Now that you know the basics of straight and curved stair lifts let’s look at some of our most popular models.
