My last chair didn't provide the support I get with this one.  This is my third office chair since I started working from home and it is, by far, my favorite.  The lumbar support is great and the arm rests are adjustable.  I'm 6'1" and I am able to bring the seat up high enough so that my knees are at the correct angle and the arm rests come up to the perfect height with my desk.  This is definitely a chair I would purchase again.
