very good firm seat
Very good seat, good build quality with correctly sized materials; but....
*The armrests are uncomfortable and anti-ergonomic, and they can't even be folded away, so I've taken everything apart for good, which leaves the protruding metal frame bare, so I'll have to adapt some DIY foam protectors to avoid damaging my wall.
*The black paint on the base is very bad because it wears very quickly and leaves immediate scratches.
*The gas strut protrudes a lot (70mm) above the minimum level of the leg, which is really very flat (which is an engineering weakness), so as I wanted to replace the castors with better quality ones (roller type) I had to find a sufficient height above the standards of the other chairs.
