KM-8520X Heavy Duty Bariatric Wheelchair — Lightweight, 20" Seat
Product Overview
The Karman KM-8520X is the lightest bariatric wheelchair available, built for users who require a higher weight capacity without accepting the bulk and weight of a typical heavy-duty chair. Engineered by Karman Healthcare with an aircraft-grade aluminum frame and a 352-pound capacity, it includes quick-release axles, attendant brakes, anti-tippers, and a seat belt as standard — making it a complete solution for bariatric users and their caregivers. Available in 20-inch and 22-inch seat widths.
Key Features
Product Highlights
Most bariatric wheelchairs achieve their higher capacity through heavy steel reinforcement — the KM-8520X reaches 352 pounds using aircraft-grade aluminum, bringing the total chair weight down to 35 pounds and making it a chair that caregivers can actually lift without a mechanical aid. Quick-release axles let caregivers break the chair down for vehicle loading in seconds. The inclusion of attendant brakes, anti-tippers, and a seat belt as standard items means the chair arrives ready for safe use without requiring additional purchases.

Primary Use Cases
5 real-world scenarios for this product
🏠 Bariatric Home Mobility
Built to support users with higher weight needs without compromising daily function or caregiver safety. With a maximum open width of 31" and a 500 lbs weight capacity, the KM-8520X navigates standard accessible doorframes and wide home hallways with confidence. The 8" casters glide smoothly across all home flooring without resistance or instability.
🏥 Medical Appointments & Hospital Use
Hospitals, outpatient clinics, and bariatric surgery programs routinely need chairs that safely accommodate larger patients. At just 35 lbs — far lighter than most heavy-duty wheelchairs — this chair can be loaded into accessible vehicles and managed by most care staff without specialized lifting equipment. Supports up to 500 lbs with a crash-tested aluminum frame.
🌳 Community Access & Outdoor Use
Quick-release 24" quick-release rear wheels roll on paved outdoor surfaces and accessible community paths without maintenance. Flip-back armrests allow easier access from wider transfer zones. The reinforced aluminum frame provides structural confidence on ramps, curb cuts, and variable outdoor terrain for users up to 500 lbs.
✈️ Transport & Vehicle Loading
Folds flat for loading into accessible vehicles, adapted vans, and standard car trunks (with appropriate vehicle width). At 35 lbs, this is one of the lightest bariatric wheelchairs available — a significant practical advantage for caregivers and family members managing daily transport logistics for larger users.
🔒 Caregiver Safety & Transfer Support
Flip-back armrests and quick-release axles create a clean, accessible transfer zone on both sides of the chair — reducing the awkward positioning that leads to caregiver musculoskeletal injuries during bariatric patient handling. Available in 20", 22" seat widths to ensure proper fit at 500 lbs capacity without lateral pressure or discomfort.
