I was able to put it together easily and it works well. The only problem was I could not for at least a week put the headrest on. I called support and they were going to send me another headrest. However I first screwed in the screws for the headrest most of the way removed them and then by laying the chair top on a bed was able to put the headrest on. Very good.
Chair is very comfortable and provides the support I was looking for. Since I tried a display model in the store I was not taking a big risk. Ordered online through my Staples store and had it shipped directly to the local store. I paid for assembly but when I arrived to pick up the chair it was NOT assembled. I got a refund for assembly took the chair home and did it myself. Instructions and packing made assembly very simple and easy to follow. I also watch a step-by-step assembly by another customer on YouTube. Chair is great but the in store experience not so much. This is an easy DIY project.
A comfortable chair with lumbar support you can feel and adjust. I have only used it for a week so far but I am noticing a definite adjustment in my posture and less low back pain. It has a wider seat and adjustable arms to allow for roomier comfort when sitting. Very easy to assemble!
