First off I ordered this on Friday 12/18 not as a Christmas present, just for myself.  It arrived on Monday 12/21.  Great delivery time. My daughter said it was a breeze to assemble.  She did it while I was at work.  I walk in the door and it was beautiful, Big & cushy.  I am sure it will not wear out as fast as my last office chair.    It was the most expensive office chair I've ever bought but well worth it.  I wish it came in the cream color instead of black but I'll get over it. I love this chair.

Pros: Big, comfy, easy to adjust, solid base.
Cons: color choice
