A Diagram of What Your Workstation Should Look Like

A summary of good ergonomic computer setup ...

"Whether you're trying to fight off repetitive stress injuries, headaches, back- and neck-aches, or you just want to feel more comfortable at your workstation, there are a few things you can do. Set up your chair and desk so the following criteria are met:

- place your monitor 18" - 22" from your body (about an arm's length)
- you should be looking slightly down (top 1/3rd of the monitor at or below eye level)
- reduce glare with a flat-screen monitor (or draw the shades to prevent sunlight from hitting the screen)
- adjust your chair height so your feet are flat on the floor, and your knees are bent slightly more than 90 degrees in front of you.
- buy a chair that supports your back from pelvis to shoulder blades
- let your arms fall naturally (sometimes a chair without an arm rest is better), elbows bent slightly more than 90 degrees."   continued ...   (Via Ergoblog)
