Herman Miller Embody vs Håg Tribute vs Haworth Fern

Hi
Ive been looking at a new chair, to replace my very old and very worn chair. Want to spend a bit this time around, since im getting a bit older, and want to take care of my back

Ive been looking at the Herman Miller Embody, Håg Tribute and the Haworth Fern
The price will be about the same for all 3 in my country ( Denmark ) since i can buy the Herman Miller refurbed and the Håg as a demo unit, and the Haworth is about the same price as the other 2 from new

I can find lots of reviews of the Herman Miller and Haworth Fern, but cant seem to find ANY reviews of the Håg Tribute
The Håg Tribute does look like a very nice chair, but again, not alot of info on it

Any info on the Håg would be appreciatet or just the cons/pros of all 3
