Would a simple cloth over the chair work? Also if you don't mind, but how much do you weigh?
As for being PROVEN to be better, I don't know and really don't care because I know it can't be worst. I like how i am able to adjust it really low, lean back while my ass is stationary, and that you can move the back rest forward so you don't have to sit all the way back just to get back support.
I don't mind at all. I am 5'9" and 185lbs.
Oh, and in the interest oh honesty, I work for Herman Miller and mainsite in Zeeland MI.
Enjoy your chairs folks, comfort is important and finding it can be tough!
