The keyboard and mouse support surface (also known as
keyboard tray/platform) plays an important role as it allows you to position yourself in a
proper body posture which will reduce the risk of developing computer related injury.
There are several advantages of having a adjustable keyboard tray; it:
- allows you to adjust it to the proper height so that you can
have knee clearance.
- allows you to adjust it so that you are not too far nor too
close when looking at the monitor. The preferred viewing distance for the computer monitor
ranges between 18 and 24 inches.
- allows you to position yourself in a neutral position while
keying. The preferred body posture is elbows and hands parallel to the floor and wrists
straight or slightly in a downward position.
- allows you to avoid unnecessary arm extension when keying or
mousing.
- allows you to free up more work space on your desk for other
tasks, and
- allows you to easily store away the keyboard when it is not
being used.
