WHILL Model C2 High Back Power Chair

The WHILL Model C2 High Back Power Chair provides enhanced upper-back support while maintaining the portability, performance, and smart technology of the standard Model C2. Perfect for users who want a flexible, adaptable power wheelchair, the High Back option gives extra comfort without compromising maneuverability or travel convenience.

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 8–10 inches. The high-back can be installed or removed easily using an Allen wrench, letting you 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-wheel technology for tight turns and superior indoor maneuverability

• Rear suspension for a smoother ride outdoors

• Compact, travel-friendly design that fits into most car trunks

The chair disassembles quickly into lightweight components without tools. With a top speed of 5 mph, a driving range of up to 11.2 miles, and a 300-lb weight capacity, the Model C2 provides reliable 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. A high joystick is another optional addon
