I own both an Aeron and a Freedom chair. The Aeron was comfortable enough, but did not have a headrest, and so I bought the Freedom with fabric-over-gel upholstery. After many years of daily use, I'm ready to replace the Freedom chair--the rough fabric hurts my elbows, and the seat pan is starting to feel insufficiently padded and presses against the underside of my thighs. I tried the Embody and like the way the seat feels and the fact that the edge folds down and doesn't cut against my thighs.
