We've had our since September of last year, normally play twice a month, for about 6 hours a session. Happy with them so far. They clean well with a damp cloth. The staples / stitching are in good shape still. The padding is still great. Wheels working fine.
1 chair suffered some rub wound, likely getting spun into a sharp edge; but normal wear and tear I would say.
Our chairs also go through alot, stored in the basement (Tight room), get brought up upstairs for game night, and then get stored in a nearby bedroom after the game, before being returned to the basement. Lots of opportunities for us to bump them and rub on walls, corners, etc
