Adjust the heights Adjust the heights of your chair and keyboard
When the heights are adjusted properly: your knees should be slightly higher than your hips with your feet flat on the floor. your forearms should be horizontal when using the keyboard or mouse.Hint! In order to do this, a foot rest may be needed.
Adjust your chair’s backrest Your back needs the chair’s firm support! The backrest helps support your lower back (lumbar region). Do not sit on the edge of your chair. Your lower back should rest lightly against the backrest.
Adjust your monitor Your monitor should be directly in front of you. It should be about arm’s length away from you (18” to 20”). When seated, the top of your monitor should be at (or slightly below) eye level.
Don’t get a pain in the neck! Using a document holder will reduce both eye and neck strain.
Rest your arms Keep your upper arms nearly vertical when typing. Prevent fatigue by resting your wrists and forearms. Allow at least 3” between the edge of the desk and your keyboard to serve as a wrist rest. Use of a padded wrist rest may be appropriate.
