I bought a tilt stool and it wobbles and rotates. I use it at my sit down quilting machine. It's very heavy and does not move from the spot. I can go any direction and swivel around to get off easily. It has air lift too. I found it on sale at Office Depot and thought why not try it. If nothing else the grands would love to spin on it. LOL I'm glad bought it. Oh and the grands do love to spin on it.
