ProActive Medical Chariot IV K4 Wheelchair with Elevating Leg Rests
The Chariot IV K4 Series is ProActive Medical's specialized entry into the High-Strength Lightweight Wheelchair classification. Built on an optimized aluminum and carbon steel hybrid frame, this platform sheds significant weight against traditional K1–K3 models, making the chair far easier for independent users to propel, lift, and load for transport.
This configuration pairs that lightweight frame with Removable, Adjustable-Height, Flip-Back Desk Arms for custom torso alignment and clean lateral roll-ins at desks and tables. Its defining feature is the set of articulating Elevating Leg Rests (ELR), which raise, extend, and support the lower legs — ideal for users managing edema, post-surgical recovery, casting, or limited knee flexion. A built-in telescoping seat rail extension adjusts seat depth from 16" to 18" on the fly, while breathable nylon upholstery, rear anti-tippers, and flat-free urethane tires on composite mag wheels round out a customizable, high-end independent mobility solution for your catalog.
