I love our new chairs and they are extremely comfortable!  I am 5'9" and they fit me just perfectly.  Since I have back issues, I was concerned about the support.  I couldn't be more pleased!  They roll perfectly without any issues.  I purchased them in green and love the splash of color they give our office.  Great chairs for the price.  I expect that you will be happy with the purchase, like I am.

Pros: Comfortable, stable and roll very easy
Cons: I assume the fabric arms could get dirty.
