How to Sit at a Computer Properly
- 1). Adjust your work desk to a height between 28 to 30 inches.
- 2). Install your keyboard tray so that it tilts down away from you, raising your wrists at a slight angle to the desk. Install your mouse tray 1 to 2 inches higher than your keyboard and angled slightly away from your body.
- 3). Center the computer's monitor at your eye level. Place a document holder nearby so that you can glance easily at items you need to input without straining.
- 4). Adjust your chair so that it is not at an exact, erect 90-degree angle. Recline slightly to an angle of 100 to 110 degrees. Use armrests only when taking a break.
- 5). Sit with your arms at the keyboard and mouse with your wrists as neutral as possible, avoiding bending them up or down.
- 6). Adjust your peripheral items such as the mouse, keyboard and document holder to customize the arrangement for your particular task; change the arrangement when you change the task. Bring the item closest to you that you will be using the most for a given task. For instance, if you are going to play games, move the mouse closer to you and the document holder further back.
