beautiful executive chair - allegedly for people with bad back with long hours at the computer.
 - but it is not comfortable for me, I am only 5’6” 
and the seat is short for me, and when one seats the pillow in the back stands out to support the lombar area. At this point you will start sliding 
forward because the seat moves in a low forward direction. You will have to constantly move back not to fall from the seat.  The special pillow with this complicated mechanism will reach your back if you recline backwards in the chair. The “pillow “ position is unpleasantly hard against your kidneys. 


Maybe this chair would be comfortable for short and rather heavy people.
Not for me and I must return these two chairs I bought.
