This chair has casters and the height can be adjusted in 4 steps. ・Seat width: 39cm at the narrowest / 43cm at the widest ・Seat length: 30cm The angled seat naturally encourages good posture, allowing me to maintain a good posture even for long periods. It seems to be a sturdy construction, and I think it's a chair that can be used for a long time by both adults and children. There are no noticeable stains or scratches, and it is in relatively clean condition. Price reduction not possible.
