Hello Raphael.37. I am 1.77. When I set the chair to maximum height my feet are flat on the floor, but this position is not comfortable for me in terms of sitting. I prefer the middle and this is optimal. You can easily adjust this until you find the most comfortable position. I am very satisfied with this chair and I often work in a home office and have no problems with my legs and back. In the meantime, I know several people who have bought this chair and won't give it up. I was able to try it out and was immediately convinced.
