Ensure peripheral items (eg, telephone) that are used most frequently are placed closest to the user so that they can be conveniently and comfortably reached.
To reduce the stress in your neck, a headset may be beneficial to reduce stretching and improperly holding the phone.
The monitor should be supported so that the top edge of the screen is at your eye level (lower if you wear bifocals).
The monitor should be placed so that your eyes are at least an arm’s length from the screen (approximately 18" – 28” away from eyes).
The keyboard and mouse should be placed together on a platform that is at least 28" wide, directly in front of you and directly beneath the monitor.
The keyboard and mouse platform should easily move side to side, up and down, in and out, and lock securely in place.
The height of the keyboard/mouse platform should allow your hands to rest lightly on keyboard or mouse with your forearms using the chair armrests for support.
