Ideally, the monitor will be just below your your eye level and the keyboard at elbow level. If you can't raise or lower your monitor, you can adjust the seat height to accommodate. This applies when you're doing things like reading a book or something on paper, writing by hand, drawing, etc. Lower or raise your chair height until your elbows and arms can rest comfortably on the desk. If you have to stay put for a while, such as during a meeting, its especially important to be sitting properly. Change your chair height until your feet are flat on the floor so you don't have to sit awkwardly.
