I think the Knoll Generation is so much better than the Embody and Aeron. I tried out all the top chairs at a Design Within Reach and the Generation was my favorite. What stands out about it is the way it moves with you, including how the back bends with you when you lean back. I find the rubber on the back more comfortable to lean against without a shirt than the mesh on other chairs. Got a good deal on it new with warranty for $804 shipped. Mine has dark frame, high-performance arms, ultra seat cushion and storm (matte black) seat and back.
Here's the best feature in the flexible back. It moves with you and goes right back into place.
And, as a bonus, here is my Human Touch Perfect Chair. Great to lie in whenever your back hurts. You can't sit upright in this chair comfortably. It's really meant for leaning back, and therefore can't be used with a traditional desk. It's such a big chair that if you and your girl are skinny you can both fit in it.
