We bought it from new @ €500 4-5 years ago
Adjustable seat height (gas strut)
Adjustable armrests (up/down, backwards/forwards, side-side)
Numerous other adjustments, see http://www.apendics.de/Wagner-AluMedic-10#1
Current Condition: Reasonable for age:
Back adjuster spring requires resetting (the store we bought it from can do it)
Slight marking on cushion, commensurate with age
We are selling it due to an office revamp.
