A Practical Guide to your own Workstation Assessment
- The chair should be at a height that your feet can rest flat on the floor with your thighs on a gentle slope down towards your knees (there should be a 90° – 120° angle between your upper body and thighs)
- The lumbar support on the chair should fit into the lower curve of your spine
- Having the back of the chair leaning back slightly will help ease the pressure on your lower back
- There should be a gap of 50 – 75 mm between the edge of the chair and the back of your knees
- Have your chair positioned close enough so that when your hands are on the keyboard your elbows should be by your sides.
- The angle of your elbow (between your upper and lower part of your arm) should be between 90° – 120° when your hands are resting on the desk. Raise or lower accordingly
- If your desk is a fixed height
- And too low you may need to install desk raisers to achieve the correct elbow ankle
- If the desk is too high, then you can use a foot rest and raise the height of you chair to achieve the correct elbow angle
The Computer Monitor
- Raise or lower the monitor so the top of the screen is approximately horizontal with your eyes
- The monitor should be positioned about an arm’s length away from you when seated
- Ideally there should be no reflected glare from nearby windows or lighting on the screen
