The New and Improved #1 Selling Stairlift in the World!

Acorn Stairlifts is the world-leader in stairlifts, helping hundreds of thousands of customers to regain their freedom and independence in their own homes. Since the company was founded in 1992, they have sold over 300,000 Acorn 120 Stairlifts worldwide.

They provide safe and cost-effective solutions to anyone suffering from limited mobility from a variety of reasons: injury, illness, disability, or simply aging.  Acorn Stairlifts is the manufacturer and provides local sales, installation, service and support across the U.S.

Acorn Stairlifts, Inc., has launched their new and improved Acorn 120 Stairlift; the #1 selling stairlift in the world.

The new Acorn 120 Stairlift offers a more comfortable, padded seat with a more modern-looking design. The seating shape and position have been adjusted as well, making for a more ergonomic ride, with even greater user flexibility.

The overall size has been reduced, which, in addition to making the seat more aesthetically pleasing, provides even more space on the staircase.

Complying with all of the current safety standards, the new Acorn 120 Stairlift has a wealth of improved features, such as the new arm interlocks, which prevent accidental movement when getting on or off, and the seatbelt has been moved higher for increased comfort when locking and unlocking.

In addition, the newly positioned paddle controls have been adjusted to make the new Acorn 120 Stairlift easier to operate than ever before.
