The Wavebone Voyager II promises a lot. It should, given the price asked. Once assembled, a straight-forward process for anyone familiar with putting a pre-fabbed office chair together, it looks impressive. It's a good, solid chair to sit in, with plenty of support where it should be - lower back, etc., and the mesh helps it to breathe and keep cool in the hotter weather. The arms swivel back and that was appealing to me as I am a guitarist and Youtube producer. One activity requires no arms (playing) and the other full arm support (editing). My only issue is that the arm supports must be moved outwards in order for the whole arm assembly to swivel backwards completely. So there is no quick and easy movement. Also the release catches on the bottom of each arm must be released in order to fold them back. Small things but niggling after time. The chair has a moveable (but not easily re-moveable) headrest which is a plus. Height and leaning adjustments work well. My only (other) issue is that the chair is about 3-4 cm short of optimum height for my needs and I cannot work out or see any purchasable way of creating a height extension. I stand 185cm so if you're in the same stature range, be aware of this. However, I welcome any solution that the manufacturer might provide after reading this. For the chair's general construction and ergonomics I give 4/5. I deduct a star for the issues mentioned above. Would I buy again? No, not unless those same issues have been addressed.
