These stools are horribly constructed. I have had them assembled less than 2 weeks and they are already wobbling. At first I thought it was just the bolts needing tightened. After I dove in I realized they are literally loose at the socket, where it is installed into the base of the seat. The bolts are as tight as needed, there is no way to solve the wobble. I am now stuck with two stools no one can sit on and no way to repair them. Definitely regretting the purchase and would not recommend them
