Ergonomics The Healthy Workstation

The Healthy Workstation…

• Choose a chair that provides support for your lower back.

• Adjust your desk and your chair to assume a comfortable body posture along right angles as shown.

• Use a footrest if your feet do not rest comfortably on the floor.

• Adjust your chair so the seat does not press into the back of your knees.

The Healthy Workstation…

• Place your keyboard and mouse at elbow level. Your upper arms should fall relaxed at your sides.

• When typing, center your keyboard in front of you alongside your mouse.

• Keep your wrists straight while typing and using the mouse. Avoid bending your wrists up, down, or to the sides.

• Float your wrists above the keyboard.

The Healthy Workstation…

• Center the monitor at about an arm’s length in front of you.

• Position the top of the monitor’s screen near eye level.

• Shelter your monitor from light sources that produce glare.

• Adjust your monitor’s brightness, contrast and font size until they feel comfortable for you.

The Healthy Workstation…

• Use alternative input products like...

– Natural form-factor keyboard: does not

force the user to bend the wrists in order

to type.

– Optical mouse: offers less resistance and

does not jam, causing stress and shocks

to the wrists
