775a... Thanks for input. Researched for a while, found Rove and other brands but could only find mixed reviews. Apart from the price, Herman Miller's definitely has something others don't. It also comes down to one's morphology... (I'm 6"2 - 195 lbs).
Before I was ever interested in a "listening chair", I sate in a authentic Herman Miller's at a friend's and as soon as I sate in, I felt very/extremely comfortable! Unfortunately, he would not sale it
