These are very nice chairs, and were not terribly hard to assemble.  The only problem, which may prove to be a deal-breaker at some point, is that there is a support bar directly under where you sit.  It’s very uncomfortable when you sit in the upright position, but not as noticeable when you are reclined.  We are small, lightweight people....I can only assume it would be even more uncomfortable for a heavier person.  Seems like a design oversight.
