Ergonomics

Chair

An adjustable chair that provides firm, comfortable support is best. Adjust the height

of the chair so your thighs are horizontal and your feet flat on the floor. The back of the

chair should support your lower back (lumbar region). Follow the manufacturer’s

instructions for adjusting the backrest to fit your body properly.

You may have to raise your chair so your forearms and hands are at the proper angle to

the keyboard. If this makes it impossible to rest your feet flat on the floor, you can use a

footrest with adjustable height and tilt to make up for any gap between the floor and

your feet. You can also lower the desktop to eliminate the need for a footrest. Or use a

desk with a keyboard tray that’s lower than the work surface.

Display

Arrange the display so the top of the screen is slightly below your eye level when

you’re sitting at the keyboard. The best distance from your eyes to the screen is up to

you, although most people seem to prefer 18 to 28 inches (45 to 70 cm). Position the

display to minimize glare and reflections on the screen from overhead lights and

windows
