Keeping yourself comfortable This section provides information for setting up your work environment and tips for working comfortably throughout the day. Computer user comfort recommendations Good Working Posture ❖ Adjust your chair height: your feet should be flat on the floor and the bottom of your thighs should be evenly supported by the seat. If your feet cannot reach the floor, use a foot rest. Avoid pressure points behind the knee or under the thigh. ❖ The space under your desk should be free of clutter so that your legs and feet are not restricted, and you can get close enough to your notebook and other items that you use frequently. ❖ Adjust the chair back rest: it should match the curve of your back and provide comfortable back support. ❖ Adjust the chair arm rests: they should be about the same height as the keyboard and comfortably support your arms, allowing your shoulders to relax. ❖ When using the keyboard, it should be centered in front of you. ❖ The keyboard and pointing device should be close to your elbow level. The keyboard should be flat so that your wrists are straight when typing. However, if the notebook is on a work surface that is above your elbow height you may need to slope the notebook to keep your wrists straight. ❖ Work with relaxed shoulders. ❖ When typing, keep your wrists straight and try not to rest your wrists on the notebook. Support your arms on your forearm area. The forearms can be supported by the chair arm supports or the desk surface. ❖ The notebook display should be tilted so that the image on the screen is clear.
