It was only a little challenging to put together and there weren't too many pieces. It is very comfortable and adjustable. I use it to work from home and this was worth it. My back is feeling so much better with this chair. I recommend this product very highly.
This is a nice solid chair for the price. Very comfortable but I have noticed some pressure on the underside of my thighs when I use it for extended periods. I do wish it had a deeper seat for that reason.
