IMPORTANT INFORMATION

The best way to avoid problems related to pressure sores
is to understand their causes and your role in a skin man-
agement program.

Your therapist and physician should be consulted if you
have any questions regarding weight relief, self-examina-
tion of skin, or individual limitations and needs.

All cushions should be selected carefully. Working with
your therapist, physician and equipment supplier is the
best way to assure that a cushion choice matches your
individual needs.

As the needs of the client become more complex, the
cushion evaluation becomes more important.
