I have the exact same problem with "sinking in" and I'm not especially large (I'm 6'2", 180 lbs). I haven't had any stability issues, and I like the Aeron much better than most other chairs I've used, but it has some drawbacks in addition to the front of the seat jutting into my thigh:
The plastic on the sides makes it difficult to sit cross-legged in the chair. Granted, I've never had a chair that let me do this very well.
It's impossible to kneel on the chair comfortably. This sounds silly maybe, but the last chair I used had a very soft cushion to sit on, and the back was adjustable such that there were spaces where you could dangle your feet. It was possible to kneel without causing much strain on feet or ankles.
I've found both kneeling and cross-legged positions to be very stable, comfortable, and conducive to proper breathing-- so long as you don't wind up losing circulation in your legs.
I am also not "large", but tall. Probably I have the "oversize" version of the chair, as my father is also very tall. Perhaps the normal version works better (smaller size of net -> less sinking in).
