Sizing is pretty accurate (2008-09-04)
I'm 5'3 and I have been using this ball mainly as an alternative to my desk chair. When I'm at home I use my computer quite a bit and my posture has been suffering because of it. I assumed it would be slightly too big but actually I find it to be slightly too small. But I'm using this as a chair, not as an exercise ball, well at least not yet. If I were to use it for that I'm sure the sizing would be correct. So if you're small like me, this ball is perfect!
