Get a good chair. Frazer says it should adjust for height and lumbar support and have a five-star base to avoid tipping.
The Canadian Association of Occupational Therapists (CAOT) recommends adjusting the chair height so that your knees are level with your hips. If your feet are not resting flat on the floor, use a footrest. Alter your chair if there is a difference between the height of the keyboard and the writing surface.
Adjust the lumbar support. The CAOT also advises adjusting the lumbar support to the curve in your lower back. Not changing the lumbar support can cause stress in muscles and joints, and alter the normal S curve of the spine. If you don’t have a chair with lumbar support, you can use a pillow or a rolled up towel, provided the support is not too thick. There’s no rule of thumb for thickness, but it should feel comfortable.
Sit up straight. Don’t work hunched over or sitting on the edge of your chair.
Place arms properly. Let your upper arms hang down and put your lower arms straight out when typing or using the mouse.
Keep wrists level. When typing, don’t raise your wrists up or down. Keep them roughly parallel to the floor. The same holds true for the mouse.
Keep the mouse nearby. Make sure your mouse is close enough that you needn’t lift your arm to use it.
Put your monitor straight in front of you. Make sure your eyes are level with the top of the screen.
Take breaks from the computer at least once an hour. Frazer suggests standing up while talking on the phone. He says this will give your spine a chance to return to its normal posture.
Reconfigure your laptop setup. If you do use a laptop, use a separate mouse and keyboard to minimize problematic posture. Set your laptop on a surface that allows your eyes to be level with the top of the screen. Put the keyboard and mouse at a level that allows you to keep your arms at a 90° angle.
