I was trying to match my existing stools and the picture and measurements seemed spot on. Once we put one of them together, that was not the case. But the stools appeared to be study and beautiful. Directions to assemble were clear and it was easy to put the stool together. I can forsee a problem in that the seat protion that sits on the swivel collar  has a large gap between the two. If you sit with your feet on the floor, the seat presses down on the the collar on one side and the oposite side rises. We are conerned that the metal swivel plate is going to pull out of the wood or bend because of this pressure. The seat gap is now smaller on one side after being sat on. (Only been sat on for one evening) Now that it is assembled it is too late to return and we have already unpacked all parts for the second stool. So I guess we are keeping them and fingers crossed they hold up.  All in all, the base is very strudy. I hope this review helps.
