42 Getting Started Selecting a place to work Seating and posture When using your computer, maintain good posture with your body relaxed and your weight distributed evenly. Proper seating is a primary factor in reducing work strain. Some people find a backless chair more comfortable than a conventional chair. Whichever type you choose, use the following guidelines to adjust your chair for maximum computing comfort. Below eye level Footrest Approximately 90° angles Correct posture and positioning of the computer ❖ Position your chair so that the keyboard is at or slightly lower than the level of your elbow. You should be able to type comfortably with your shoulders relaxed and your forearms parallel to the floor. If you are using a conventional chair: ❖ Your knees should be slightly higher than your hips. If necessary, use a footrest to raise the level of your knees and ease the pressure on the back of your thighs. ❖ Adjust the back of your chair so that it supports the lower curve of your spine. If necessary, use a cushion to provide extra back support. Lower-back-support cushions are available at many office supply stores. ❖ Sit with your back straight so that your knees, hips, and elbows form approximately 90-degree angles when you work. Do not slump forward or lean back too far.
