This chair is sooo comfortable... too bad I don't know what it is!

I purchased this chair a few years ago because I love the look and most importantly, it is comfortable. I am a big guy and it fits me like a glove. However, I can't find any manufacturers mark on it. The material is tufted green vinyl. The frame is made out of brushed stainless steel. I forgot to measure it when I took the pictures but I would have to say its roughly 30 inches high by 24 inches wide by maybe 36 - 40 inches long. A friend said she thought it was a chair by Eames, but I have looked at the chairs they made for Herman Miller and tend to disagree. Anyone have any ideas? Thanks!
