The chairs arrived in good condition but at the wrong address.  Had to go pick them up down the street.  When I opened the first chair and read the instructions it stated the unit was a 220# capacity chair.  I purchased it because the add stated it was a 300# capacity.  After going through Wayfair and getting an assurance from the product provider, I went ahead and assembled the first chair.  Everything went together fine.  Lumbar support is good and overall the chair feels sturdy.  Jury is still out as the chair leans slightly forward and the tension adjustment does not work. The set up might be a good thing, so I am waiting on others opinions.  Upon further inspection, by my son-in-law, we found the paper instructions had an error.  If I had looked closer at the parts, I would have seen it.  After correcting the error the chairs turned out fine. We like them.  They do need to do a better job with their assembly instructions.
