Harmar CSL500 Helix Curved Stair Lift

The Helix Curved Stair Lift offers a narrow profile that mounts closer to the wall, with tighter bends. The ride is ultra smooth and whisper quiet! Manufactured in the United States, every Helix CSL500 is engineered and built to order. Each custom stairlift is unique to the home and stairway it is installed to. This custom design allows the Helix stairlift to have a smaller footprint, quicker install, and outstanding performance. The build and delivery methods also allow installers to work more quickly and efficiently when they arrive at your home. The lift can be installed with minimal disruptions to you. Perfect for a stairway with a 90-degree turn, 180-degree turn, or even a spiral staircase. The Helix can even be built to accomodate multi-story applications. An ergonomically-designed seat features swivel seat and “flip-up” arms to make entry and exit easier. Custom color and fabric options are available to help make the Helix Curved Stair Lift a tasteful addition to any home.

Choose from a wide selection of seat colors and pad coverings for a customized application, inside or outdoors. Whether synthetic, velour, or leather, all fabrics are designed to be durable, easy to clean and flame-resistant.
