I was  replacing my old office chair and really dreading the assembly of this new one. Old chair was horrible to assemble and I had to have help doing it. When this chair arrived I delved right in and found it to be so very easy to put together. It took me about 20 minutes and I am very proud of the result. I got the mesh chair so it would be cooler than my old fake leather. Very comfortable and love the feature that allows the arms to fold up giving the chair ample room to slide under desk and save space. You will love this chair.
