How can we help?

What do you get from your Siena Stairlift?

The Siena is a product of 150 years of experience and a tremendous amount of careful engineering. Its fresh design is clean, compact and simple and its vinyl upholstery is easy to clean and practical for everyday living. The Siena’s longer arms are designed to make you feel as safe as possible and its robust weight capacity (350 lbs. on straight stairs and up to 352 lbs. on stairs that turn)  makes it accessible for many. What defines the Siena is its simplicity and reassuring practicality.


The Siena stairlift comes with vinyl upholstery, available in 6 different colors.

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 narrow staircases

The Siena is a great option for narrower staircases. It 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.

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.
