ProActive Medical Chariot IV K4 Wheelchair with Elevating Leg Rests
Model: Chariot IV K4 High-Strength Lightweight Positioning Series
Availability: In Stock — Ready to Ship
Lighter to Push, Built for Real Leg Support
The ProActive Chariot IV K4 is a high-strength lightweight wheelchair built around an aluminum and carbon steel hybrid frame. By shedding weight compared to standard manual wheelchairs, it's genuinely easier to self-propel and easier for a caregiver to lift into a car for travel.
This configuration includes tool-free articulating elevating leg rests with padded calf supports — well suited for users managing edema, post-surgical recovery, casting, or limited knee flexion. Height-adjustable, flip-back desk arms let you roll flush to a table or desk, and a telescoping seat frame expands depth from 16" to 18" as needs change, without replacing the chair.
Key Features
- High-Strength Lightweight Frame: Aluminum and carbon steel hybrid construction reduces propulsion fatigue and caregiver lifting strain.
- Articulating Elevating Leg Rests: Tool-free front riggings raise and extend smoothly with padded calf supports for cast placement or vascular relief.
- Height-Adjustable Flip-Back Arms: Desk-length armrests adjust vertically and flip back for zero-barrier side transfers.
- Telescoping Seat Depth: Expands from 16" to 18" on the fly as needs evolve.
- Flat-Free Tires: 24" composite mag wheels with solid urethane tires and 8" solid front casters for maintenance-free tracking.
- Standard Anti-Tippers: Adjustable rear stability wheels for confidence on inclines and thresholds.
- Breathable Flame-Retardant Nylon: Distributes pressure evenly and wipes clean for reliable hygiene.
Specialist Insight: Most high-strength lightweight wheelchairs cut positioning features to save weight, but the Chariot IV keeps full adjustability without adding bulk. The real day-to-day advantage is how the telescoping frame and articulating leg rests work together — a specialist can expand the seat depth from 16 to 18 inches so the leg cushioning still tracks naturally with the user's anatomy as the legs elevate, rather than the two adjustments working against each other.

Frequently Asked Questions
Q: How does this lightweight frame compare to a standard wheelchair?
A: Standard manual wheelchairs are typically all carbon steel, making self-propulsion and trunk loading physically taxing. The Chariot IV's aluminum and steel hybrid frame sheds significant weight while retaining the structural rigidity needed for daily, multi-year use.
Q: What's the benefit of the telescoping seat depth?
A: Standard frames have fixed dimensions, so extra thigh support usually means a new chair. Built-in frame extensions here let a specialist expand seat depth from 16 to 18 inches, distributing weight over a larger surface to help prevent pressure points.
Q: How do the flip-back desk arms help with tables and transfers?
A: Fixed armrests can block the chair from rolling under a table. These shortened desk pads slide flush to work surfaces and adjust vertically for arm alignment, then unlock and swing fully back for lateral transfers.
