Purchased three of these chairs. Two assembled fine (once you figure out how to attach the swivel mechanism); however, when assembling the third stool one of the welds on the leg that allow you to attach to the bottom support ring popped off (cheap Chinese welding). There is no way to fix unless you have a spot welder. I called Wayfair customer service, explained what happened and they quickly shipped a replacement chair - great customer service.  The assembled chairs look great, but I am a bit concerned about how they will hold up over time given the problem with the one chair.
