Liberty FT wheelchair by Ki Mobility, with Jay Union back, and Roho QS1010C air cushion. Seat height to frame seat is 15". Add extra for cushion. This wheelchair was designed to allow an occupant to "walk" it using foot propulsion. The handhold on the wheel enables self-propulsion as well. The chair folds to enable transport. The back is rigid and does not fold, but has a quick-release mechanism to allow easy removal and replacement. The chair wheels are quick-release as well, so it can become fairly compact.
