This chair is very comfortable for me and my husband.  There are many adjustments that can be made to make it perfect to fit your desk.  I am 5'2" and my husband is 6'4" and I can adjust so that my feet are on the floor.  I gave it 4 stars because when he leans back his head is above the headrest and also we have this on tile floor and I feel that the rollers don't roll as smooth as they should.  Other than that it's great.
