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.
It can be hard to remember all the "rules" when you're setting up your workstation. So, I'm providing a link to a diagram that you can print off and tape up next to your desk:
