All items to be assembled should be as the directions in the box for the chair. For that alone I would give it 5 stars. Now for how the chair feels. Only have it for about five days so for now its quite comfortable but lets give it another couple of weeks and see how it feels. Would recommend this product and hopefully all the products from this company come with easy to assemble directions.
The back of this chair causes back pain. It is a pretty harsh curve and though it was advertised as tiling the entire chair tilts but the back of the chair won't go back.
II had a little trouble mounting the casters to the base but a customer-service person was helpful and gave me the info I needed to get them seated properly. The rest of the assembly was quick and easy and the finished product sturdy and comfortable I'd recommend it to anyone with a home office.
