First, after 4 months of use, the seat and back rest comfortable (use: Gaming either ± 10hrs / day 7/7).
However, one of the leather armrests is damaged after several friction against the desk ... My advice: protect the front armrest with coarse black tape, AC pass unnoticed and this will prevent wear on duration.
Geek second point: my cat loves squatter chair when nobody is on it and planted his claws like ... my advice: do not take cats.
Last but not insignificant: at this price, do not expect a chair pro gamer or tenant of the offices of the Elysee Palace, you will have a good product at a low price that will delight your little gamer back. If like me you are more than 1m75, you do not care for the headrest, this is based neck and it's not so bad after games 10hrs!
Conclusion: 4 stars for a product at this price? Yes, and that's why I bought one second.
