Ki Mobility Liberty Adult Tilt-in-Space Wheelchair

An exceptionally lightweight adult tilt-in-space manual wheelchair utilizing advanced high-pressure metal molding. Unlike traditional heavy rigid tilt frames, the Liberty is engineered to provide the physiological benefits of dynamic positioning while offering true portability and independent foot or hand propulsion. A core design feature ensures that the front seat-to-floor height remains perfectly constant regardless of the tilt angle, providing uninterrupted grounding and pelvic stability for active foot-propellers. Its highly adaptive modular layout permits rapid reconfiguration of frame metrics without requiring auxiliary parts, making it highly preferred for stroke rehabilitation environments.

  Specifications:

  • Weight Capacity: 250 lbs (113 kg) standard framework capacity; Heavy-Duty (HD) structural package option expands to 350 lbs (159 kg).

  • Transport Weight:

    • Folding Base: 25.8 lbs (11.7 kg) baseline stripped transport weight (calculated using a 16”x16” frame with quick-release wheels, footrests, and armrests removed).

    • Rigid Base: 24.5 lbs (11.1 kg) transport weight for facilities or environments not requiring a folding crossbrace.

  • Tilt System: Smooth mechanical 0° to 20° gas-spring active tilt range; customizable setting packages can alter the total tilt track range from -7° to 27°.

  • Seat Width Range: 14" to 22" (36 cm to 56 cm).

  • Seat Depth Range: 14" to 20" (36 cm to 51 cm).

  • Seat-to-Floor Height: 13" to 20" (33 cm to 51 cm).

  • Side Frame Component Weight: Highly optimized high-pressure molded side frame pieces weighing just 2.8 lbs (1.27 kg) each.

  • Backrest Hardware: Features an angle-adjustable backpost variable from -5° to 25° in 5° increments, paired with an optional lever-actuated fold-down mechanism that collapses the back canopy flat against the seat framework for vehicle transit.

  • Wheel Architecture: Fully compatible with exclusive magnesium Maxx Mag wheels (available in 20”, 22”, and 24” configurations) which compress the total operational chair width by 1 full inch compared to composite alternatives while boosting frame stiffness.

  • Crash-Test Rating: Fully transit approved and certified to meet ANSI/RESNA WC-19 safety standards for forward-facing vehicular passenger transport.
