These are nice stools for the price. I would a socket to get the allen screws mostly tightened as there are a bunch. The first chair took about 45 minutes to assemble then about 25 after that. They can easily be put together with one person. 2 downsides to the chair. The 24 and 30 inch legs are not easily switchable, we hoped they would be. I replaced the screws with pop out holders and this solved the problem. We wanted this as we have a counter height table and did not want to have buy seperate chairs that would sit in the attic instead of just borrow them from the bar. The other downside is be careful tightening the screws. there is not much thread and if you try to get them to tight you will strip the whole. Would be nice if they would have used nutcerts as this would solve the issue. Overall a decent stool for the price.
