I bought this because I needed a seat that would help me keep my posture healthy while I paint and draw, and a friend recommended I try a saddle stool. This one seemed like a good starter to try. It arrived quickly, was easy to assemble, and is exactly as pictured. I like that I can raise and lower its height by pulling up on the lever. It swivels beautifully in full circles. The wheels move easily, but at the same time, I haven't had trouble with it rolling across the floor (it's an old house, and there's a slight slope in areas), so I'd say it's my ideal amount of rolliness. The base is narrow enough that it doesn't take up too much space, but I don't find it tippy. And yes, it does help me to maintain a better posture. The seat itself is comfortable and ergonomic. I couldn't sit on it exclusively (sometimes, you just want to lean back on something and rest), but it's perfect for my work. All in all, I like it! I'm very glad I bought it.

it's just perfect

Really good. Its comfortable. Does not take lots of space.
