The WHILL Model C2 Power Chair with High-Back Support

Product Overview

The WHILL Model C2 Power Chair with High-Back Support delivers the same award-winning performance, portability, and smart technology as the standard Model C2—while offering additional back support when you need it.

This configuration includes the standard Model C2 seat back, with the option to add a high-back support attachment that increases back height by approximately 20 inches. The high-back can be installed or removed easily using an Allen wrench, allowing you to switch between standard and high-back setups based on your comfort, activity, or travel needs.

Compact • Powerful • Flexible Support

Designed for active lifestyles, the WHILL Model C2 features patented omni-wheels for tight turns, rear suspension for a smoother ride, and a compact footprint that works just as well indoors as it does outdoors.

The chair disassembles quickly without tools and fits into most car trunks. With a driving range of up to 11.2 miles, a top speed of 5 mph, and a 300 lb weight capacity, the Model C2 provides dependable daily mobility—now with optional enhanced back support for added flexibility.

Control your chair with the intuitive joystick or through the WHILL smartphone app, which allows for remote driving and locking.
