Only get these stools if you're putting them on a solid hard surface. They're too tippy on plush carpet. The base isn't heavy enough to counterbalance the heavy top portion. I'm  afraid of the stool falling backwards if I lean back to hard. My other stools I had didn't have a problem but they weren't as top heavy as these are. 

I tested the stool on a hard surface and it's still rocked some, but nothing worrisome like it is on carpet. 

As a side note,  the seat sinks down quite a bit when you sit on it. Not a very strong hydraulic.
