Purchased 2.... The first one went together perfectly and it seems sturdy.  The swivel seat works well.  Comfortable, for a hard, wood seat (for short term sitting).  Style is great as well. 
The second stool was defective but I don't think it is fair to leave a bad review for that reason.  The spindles would not screw into the legs - neither one of them.  So it was clearly a manufacturer defect.   I called Wayfair and they were quick to help me with a replacement. So the 5 star review if for the first stool,  which seems great so far, and for Wayfair customer service!
