We bought this computer chair online which I was very reluctant to do since I couldn't try it out but it came sooner than what they had told us.  The only problem was that there were no instructions in the box in English how to put it together but that was no problem I found it online. I love the chair its good support for the back and its high enough off the ground since me and my husband are both  6 feet tall. And since the seat is high we  both have knee problems its easier to get off the chair.
