we ordered two sets (8 each) of these chairs in grey for our conference rooms.  The first set was difficult to attach the back to the base and the screws were often loose in the box.  The second round we ordered, those issues were fixed, but the chairs have this awful orange tag on the back of the seat - very ugly. They are a warning and likely ordered by an attorney as they advise against tipping back or 250+ pounds.  Like anyone is going to read the tag on a chair.  Anyway, they are very hard to get off because they are sewn into the seam.  But, the chairs are comfortable and look good and Wayfair customer service on the one that had a small rip was top notch.
