Heavily adjustable, monotube chair.

1. Assessment

Not really a model I would call nimble; quite asside from the bulk of this demonstrator (thrust on me in place of a 14″‐or‐so RGK FX!!?). This hypothetical star‐rating is particularly generous, based largely on the potential for a more supportive seat and the much improved footplate, compared with the folding Ottobock’s.

The ZRA I tried was fitted with a carbon‐fibre, rigid seatback. The specific placement and so on did not suit me. I would like to properly explore rigid seating (for installation on an appropriate chair!).
