I don't know that this does, but the Aeron comes in three different sizes. You can adjust the tension of the fabric base (that's the twisty knob on the right-hand side), also.
I just reached down and fiddled with that. The knob on the right adjusts the tilt tension.
The store where I bought the Embody also had the Aeron in all three sizes, and I tried both the B (medium) and the C (large) frames, fiddled with the tension knobs, and still didn't like it as much.
