If you are looking for an adjustable height stool, this isn't it.
This works as expected but it DOES NOT match the description or pictures. There is only one side, meaning you can't flip it to adjust the height.  If you want to change the height you need to unscrew it and reassemble it at the lower height. Pretty annoying considering this is a 40 dollar stool. I'd return this for a refund if I hadn't thrown away the packaging.
