The ProBasics K4 Lite wheelchair with a 20-inch seat width is a high-strength, lightweight manual mobility chair engineered specifically to deliver spacious seating comfort, customizable ergonomic positioning, and dependable daily performance for larger adult users. Built around a reinforced, lightweight metal alloy frame, this Medicare-coded K0004 wheelchair safely supports user weights up to 300 lbs while keeping the overall frame weight manageable for caregiver handling, vehicle loading, and self-propulsion. Ideal for private home care, rehabilitation therapy clinics, and assisted living facilities, it pairs dignified pelvic comfort with clinical versatility for both short-term post-operative recovery and long-term daily living.
Positioning adaptability is central to this 20-inch seat width configuration, which is coded under E2201 for non-standard wide frames. It features a factory 16-inch depth that can quickly expand from 16 to 18 inches using an included seat rail and upholstery extension, adapting seamlessly to changing thigh support requirements without purchasing replacement slings. Height-adjustable flip-back padded armrests (10″ to 14″) slide effortlessly under dining tables and desks while opening an unobstructed lateral pathway for sliding-board transfers. Outfitted with tool-free elevating leg rests with padded calf panels to alleviate lower-limb swelling and joint stiffness, 3-position quick-release rear axles for push-button wheel removal and hemi-height foot walking, solid flat-free polyurethane tires, composite front casters, wrap-around height-adjustable back upholstery, factory-installed adjustable rear anti-tippers, and positive push-to-lock wheel brakes, the ProBasics K4 Lite delivers smooth, puncture-free mobility across indoor rooms and outdoor paths.

Who Is This For & Everyday Applications
-
Larger Adults & Broad-Framed Users: The 20-inch seat width provides ample hip room and prevents lateral skin rubbing without moving into heavy bariatric categories.
-
Circulation & Post-Surgical Support: Tool-free elevating leg rests raise the lower extremities to relieve knee strain, alleviate lower-limb edema, and support leg casts.
-
Independent Foot Propellers: Quick-release 3-position axle brackets allow the frame to drop to hemi height so users can walk the wheelchair forward using their feet.
-
Workstation & Dining Accessibility: Armrests adjust between 10″ and 14″ to slide under desks and kitchen counters, and flip back completely for bedside sliding-board transfers.
-
Effortless Car Trunk Loading: Quick-release rear axles pop off instantly with the press of a button, drastically reducing frame lifting weight for trunk stowage.
-
Incline & Ramp Safety: Factory-installed adjustable anti-tippers prevent backward tipping when negotiating wheelchair ramps, door thresholds, and uneven ground.
Usage, Adjustment & Routine Care Guidance
To unfold, press downward firmly on both outer seat rail tubes until the folding cross-brace locks fully open and the nylon seat sling is completely taut. Align the elevating leg rests over the front receiver pins and rotate inward until the locking pins click firmly into place, adjusting the leg rest angle and calf pads to match user comfort. To change armrest height, press the adjustment buttons on the side support tubes and slide the padded rests to any desired height between 10 and 14 inches. For vehicle transport, press the center push-button on each rear wheel axle to detach the drive wheels from the frame. Always engage both push-to-lock wheel brakes securely before standing up, sitting down, or transferring. Clean the frame and nylon upholstery with a damp cloth and mild soap or hospital-grade disinfectant wipes, drying completely with a clean towel.
