84 Appendix B Safety, Use, and Care Information
You may have to raise your chair so that 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.
