Don't buy this chair. I bought this chair in October 2022 and in March 2024 the hydraulics stopped working on it. This is not an easy fix if I can even fix it. This chair didn't even last two years.
The enclosed instructions recommend ordering a set of soft wheels (around $25 rather a lot for a $90 dollar (on sale) chair) if you want to use it on wood floors. Of course other chairs probably have the same problem with wood floors but don't tell you about it.
