environment contributes to your comfort and productivity:

•
Work Surface Height - Your work surface should be height adjustable.
To ensure that your worksurface is at the correct height, first adjust the
height of your chair so that your feet are firmly on the floor, then adjust
the work surface height until your forearms are parallel to the floor
when you have your fingers on the keyboard or other input devices.

•
Chair - Your chair should provide a comfortable sitting position
including features such as a height and tilt adjustment feature, curved
seat edge, a stable base (for example, five legs and castors, adjustable

•
Work Surface Arrangement - Make sure that all elements of your HP
PC system for example, monitor, document holder, keyboard, mice and
other input devices, and headphones and speakers- are optimally
arranged and adjusted to meet your personal requirements. For
example, if you are primarily using the keyboard, place it directly in
front of you, not to the side. If your work involves extensive use of a
mouse or other pointing device, place that device directly in front of
your left or right arm. If you are using both a mouse and keyboard, place
them both at the same work surface height and close together. If a palm
rest is used, the height should be flush with the front edge of the
keyboard. Other items, such as your telephone or notepad, should also
be considered.
