Self Ergonomic Checklist: A checklist of your workstation setup.
After adjusting your office fit, your feet should be flat on the floor or footrest with the upper legs parallel to the floor and adequate knee clearance.
The upper third of the monitor screen should be at eye level (varies with bifocals), and the monitor should be at about arm’s length from you.
The keyboard should be placed so that your forearms are parallel to the floor and your upper arms hang freely at your side.
The chair should be adjusted so that it conforms to this position, fits the curve of your back and lightly supports the forearms.
