My first chair had an issue from shipping, but the support quickly corrects the issue. 

Overall, really like the chair. Quite comfortable. One helpful note if you get this chair (at least, one of the fabric versions), as you are putting the top half (back cushion piece) onto the bottom half, there’s a little Velcro flap that opens so you can see what you’re doing to slide it in correctly, there are specific spots that need to align for it to slide all the way down and lock into place. 

The arms are smooth, and it looks really nice.
