Step 5: Slide your hand beneath
your buttocks to locate your
lowest bony prominence,
usually the ischial tuberosities.
If necessary, your clinician or
caregiver should assist you.
IMPORTANT Adjustment Notes
• You, your clinician(s) and / or caregiver(s) should check the cush-
ion overlay daily to ensure that you have not bottomed out (ie. lost
air and sitting on the base of the cushion). If you bottom out, the
therapeutic value of the cushion overlay is lost. You should also
check to be sure the cushion overlay is not over-filled with air. The
cushion overlay will work best with approximately 1/2" - 1" of air
between you and its base.
• The AIR FLOATATION cushion overlay may be affected by changes
in altitude. You may have to repeat Steps 1 - 6 above as you
change altitudes.
Step 6: Leaving one hand in
place beneath the lowest
bony prominence, use the
other hand to open the valve.
As air is released from the
cushion overlay, you will
begin to sink into it. When
your fingertips touch its
base, close the valve.
Approximately 1/2" - 1" of air
should be between your low-
est prominence and the base
of the cushion.
