This stool is fantastic except for one flaw. The seat doesn’t stay attached to the base due to a design flaw. The metal grommets that the bolt goes into to hold the seat to the base comes loose because it doesn’t have anything preventing it from pulling out. 
The base of the seat should be flipped over or there needed to be a filler so that the grommet can’t be pulled out. 
I sat in the stool one time before it came loose. I tried another and the same thing. 
I’ll be contacting Wayfair customer support tomorrow (Monday) 
Other than the one design flaw, the stool is a great buy! And I would give it 5 stars.
