The Chariot IV Wheelchair is ultra-lightweight, yet extremely strong & durable thanks to its aluminum and carbon steel frame. It is specially designed to allow for custom seat backs and accessories and includes an adjustable-depth seat. The rear wheels can be quickly and easily moved between three separate axles to adjust the seat to the ideal height for the user or to angle the seat back. Other comfort adjustments include armrest height, seat back height and the height and angle of the front caster wheels – all allowing you to tailor the Chariot IV to your specific needs.
