I have a chair very similar and its quite comfy, but it broke. On mine, the chair sits on the stand through a single narrow post, and that post has a bushing around it to keep the chair from wobbling. Apparently the bushing didn't last too long and now the chair wobbles all over the place. If you buy the chair, take a look at the connection down there. If it looks very flimsy... I would move on to a different chair.
