Besides the broken damper receiving the package (quickly replaced by the seller), a broken wheel after 10 days of use on smooth concrete !! (NB: I weigh less than 100Kg !!) Reported but still not replaced! Low padding at the base (thick padding only on the sides of the seat, where it does not pose her butt !!), we feel the screws through the padding of the armrests. Furthermore the seat is not stable, there is play in! In conclusion, if you have the money, buy something else!
