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. Or you may lower
the desktop to eliminate the need for a footrest. Another option is to use a
desk with a keyboard tray that’s lower than the regular work surface.

m Position the mouse at the same height as your keyboard. Allow adequate

space to use the mouse comfortably.

m Arrange the monitor 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).

m Position the monitor to minimize glare and reflections on the screen from

overhead lights and windows. You may want to use a tiltable monitor
stand. The stand lets you set the monitor at the best angle for viewing,
helping to reduce or eliminate glare from lighting sources you can’t move.
