What 21st Century Scientific does

21st Century Scientific, Inc. is a privately held, founder-controlled US manufacturer of BOUNDER power wheelchairs, headquartered and produced in Coeur d'Alene, Idaho. Founded in 1979 by Ronald E. Prior, Ph.D., the company progressively developed its product line from a bare-bones power wheelchair motor kit to a complete BOUNDER wheelchair platform launched in 1988. The company sells four custom-fabricated rear-wheel-drive models — BOUNDER 300 (up to 300 lb), BOUNDER 450 (up to 450 lb), Big Bounder 600 (up to 600 lb), and Big Bounder 1000 (up to 1000 lb) — each built on a steel TIG welded frame with rugged gearless motors and configurable LiNX or R-net programmable electronics.

Each chair is custom-built to individual user specifications in close coordination with authorized dealers, therapists, and end users. The technical platform centers on a rear-wheel-drive architecture with proprietary systems including Independent Drive Wheel Suspension (IDWS), the PSE2 scissor-lift Power Seat Elevator, Dual Independent Power Elevating Legrests (DIPLR), Power Tilt/Recline/Anterior Tilt, and Sliding Back Power Recline. Modular upgrade packages extend the base platform into high-speed (up to 8.5 mph) and off-road configurations, and an accessory ecosystem (LED lighting, electric horn, electric leg bag emptier, RAM device mounts, rear-view mirror, gun mount) is engineered for compatibility with most third-party 24V wheelchairs. The company also produces BOUNDER Plus Gurneys / Prone Carts.

Revenue is generated primarily through hardware sales of custom power wheelchairs via an authorized US dealer network and direct phone/email/contact-form quote requests. Pricing is not publicly disclosed; customers request free quotes and configure options via downloadable PDF order forms. The company has no disclosed funding, operates within a 11-50 employee range, and serves active, heavy-duty, and extreme-bariatric users across the United States as its sole operating geography.
