I haven't been able to assemble the chair. The casters fall out of the assembly and there is a part that says the cap must be removed and I can't get the cap off. I have asked for Wayfair help and got a response 3 days ago that someone from the warehouse would contact me soon. Since then, nothing. If Wayfair can help me assemble this chair and it is good I might change the rating. But compared to a similar chair I easily assembled 3 years ago, the assembly instructions and process on this one is bad.
