I'm a retired pipefitter with 40 years experience putting things together. The problem with this chair is the way they built it. If you didn't have any trouble putting this together, you got lucky. I had some trouble, it took a lot longer than it should have, because of hole misalignment. They should have just used through-bolts instead of the threaded inserts that can be a real pain to work with. I'm mildly disappointed in this purchase because of the quality. It looks okay and it's fairly comfortable, so I won't be returning it, but it's not as nice as I had hoped it would be. The manufacturer would be well advised to stop building them like this. Just use through-bolts and people will be a lot happier with how it goes together. Pay as little as possible for this chair and don't expect too much. Otherwise you may end up returning it. Hope this helps someone.
