How can we help?
Key features of your Siena stairlift
From different widths of seat to different colours of upholstery, once it’s installed you will never believe that the Siena wasn’t there all along. Take a look at what else makes the Siena the most adaptable stairlift in our range.

Perfect for straight or curved stairs
The rail your stairlift needs is determined by the shape of your stairs, but no matter what their shape is - straight, curved or spiral - a Siena chair can be installed in your house.

A wider seat for added comfort
A rounded back and wider seat and are just a few of the features that make the Siena a simple yet sturdy chair. It was designed to help you feel as comfortable as possible.

Ideal for all staircases
The Siena is a great option for staircases of all sizes. It is our widest and deepest chair and has a curved seatback, allowing you to sit further back in the seat, so that your knees don’t stick out and knock against anything. Customizations are available to fit the stairlift into tight spaces.

Longer armrests
The armrests of the Siena are longer than our other models. They’re perfect for leaning on for a bit of added support and make you feel more stable as you get in and out of the chair.

Equipped with a backup battery
Your Siena will keep you moving even in the event of a power outage. When all your other appliances let you down, the battery fitted in your Stannah stairlift will keep it going.

An intuitive seat belt
Your Siena comes with an easy-to-use, retractable seat belt, fitted to the arms of the chair. That means easy access and no fiddling with clasps - you can do it up with just one hand.
