This is absolutely GREAT!! I owned an aeron chair, and tried on mirra several times, also compared it to other chairs like setu, leap etc. but this is the best one.
The adjustment is crucial, for the first month I own it, I didn't feel any extraordinary about this, and become frustrated because of the money I paid, then I have a friend coming from HM to help me adjust it right. O man, it jumped from "normal" into "wonderful". The whole back curve is adjustable, and it fit my back perfectly. After I sit on my old dinning chair for like a whole afternoon I returned to my embody, I can feel the sore and stressed muscle on my back being hugged by the chair and it just feels everything return right.
I used to be a terrible forward-leaning working person, that's why my lumbar got some issue even before I reached my 30. That's why I am quite picky about my working chair. Aeron did a good job, but Embody is better. Embody helped me to recline much much more than I used to, just because my back feel great leaning on it. I turned to recline caz I love the feeling of my back being fully touched and fully hugged. It's not too stiff but not too soft (somewhat I don't like Aeron is its back is harder than embody, I don't like the feeling of "pushing" when I sit), just right at that point.
I didn't have back pain after whole day working on Embody, which is the best thing about it.
Absolutely a full score. Once you adjust it right, it is the best ever.
