First there was a nut on the back that the arm attaches to that is mounted crooked and didn't line up. I was able to make it work but the arm is in a bind and afraid it might break eventually. It doesn't have the free movement required for the reclining. The other issue is in the design that there is not and option either the back is straight up and rigid or all the way down reclining. Would have preferred a little tension so you could sit back a little. Not as comfortable as I had expected.
