in a way, i'm envious of your problem. i wear a suit everyday to the office and wear my designer clothes like... when i go out for dinner once a week and on the weekends.. if i go out. i have a couple pairs of jeans so even if the quality was really so bad, it would take years before it showed up for me.
the eames is a pretty good chair... have sat on it many times and it is quite comfortable. i have not sat in the new "taller" version, but the original is best for someone 5'9'' or shorter. i am 5' 10'' and the original is just a little short
Writing this while sitting in a grand repost. Nothing special about it from a comfort/ergonomics standpoint--stressless is far better and I venture that even the piobaire chair is more comfortable. This is a design object. I will say the fabric is very nice though.
