Was unfortunately sent with Hermes, where people probably are completely incapable, so we had to pick it up on the spot !!! Construction takes a bit, but is good to create thanks to instructions. If you tighten all screws properly moves as well do nothing. If necessary, you can compensate for uneven ground by adjusting the feet. Levels are well adjusted and you can tell a clear difference. Overall very satisfied, a real bargain for good quality!
