My first chair came with a broken seat base, after contacting Wayfair, they sent a new one out right away and I had it in my hour within a week.   The chair was very easy to assemble, and it very comfortable.   The adjustments are very nice,  sits a bit higher than my old chair (which was broken and wouldn't raise, so it's nice to not feel like I'm sitting on the floor now).    I would highly recommend this as an office chair or home use.
