In order to be comfortable at your computer workstation the following
steps should be used to ensure the workstation fits your needs. If
you feel fatigued or start to experience muscle pain use this checklist
to re-evaluate your workstation. Do not be afraid to adjust your workstation.
Remember that the best cure for musculoskeletal injuries is prevention.
Adjusting Your Chair
- Raise or lower the chair until the edge of the seat pan
is just below your kneecap when you are standing
- Sit with your feet resting flat on the floor and your legs at a 90-110
degree angle
- Allow enough space for a closed fist between the edge of the seat
pan and the back of your legs
- Adjust the backrest to support your lower back. You may need to move
the backrest up or down as well as towards you, or away from you.
the ADJUSTABLE Work Surface
- Sit with your arms hanging straight at your side.
- Adjust the desk or keyboard tray to be level with your elbows
- Raise your forearms to create a 90-degree angle at the elbow.
the Non-adjustable Work Surface

elbow.
