This innovative design enables the seat to rotate smoothly during travel, creating a highly adaptable solution for tight or challenging stair layouts. It’s a standout feature that helps deliver greater flexibility and ease of use in the home.

Single Rail Design

The Flow X is designed to work well even on narrow or steep staircases, using a single streamlined rail that can be installed on either side of the stairs. Its compact design keeps the lift close to the steps, helping preserve open stair access and allowing other members of the household to move comfortably through the space.

Light Assist

At Windy City Stair Lifts, we know that feeling safe and comfortable starts before the ride even begins. That’s why the Flow X features innovative Light Assist technology, designed to brighten your path and make every trip up or down the stairs feel more secure—especially during the evening or in dimly lit areas.

Built with both style and practicality in mind, Light Assist uses motion-activated lighting to softly illuminate the seat, footrest, and surrounding staircase as you approach. Subtle lighting within the armrests adds extra visibility during travel, while easy-to-read seatbelt indicators clearly show when you’re ready to ride. With customizable brightness and a sleek, integrated look, Light Assist adds an extra layer of confidence and convenience to your everyday routine.
