Nice looking chair and very easy to assemble. Excellent instructions & warranty. Excellent (fast & free) shipping. I would have rated it a 5 but it is a little firm for me...a little uncomfortable after sitting a while. But that's a personal preference/issue.
Easy to assemble in just a few steps. Provides good back support comfortable chair. Chair height is adjustable bit arm rests are NOT independently adjustable which is ok for me as they are at the perfect height for me. Casters roll smoothly and quietly on my hardwood floor. Exceptional value at $89.
