ROHO HARMON cushion - Manual (Page 6)

ADJUSTMENT INSTRUCTIONS FOR HARMONY CUSHION:
STEP 1: Place cushion on
chair according to the direc-
tional labels. Make sure it
is centered and the air cells
are right side up, with air
valve in front, left corner.
Turn valve
counterclock-
wise to open.
STEP 2: Slide the pump’s
rubber nozzle over the valve
and inflate the cushion until
it begins to slightly arch. STEP 3: Pinch the pump’s
rubber nozzle and turn valve
clockwise to close. Remove
pump.
STEP 4: Have the user sit
in the chair, making sure
the cushion is centered un-
derneath. The user should
be seated in their normal
sitting position. STEP 5: Slide your hand
between the cushion’s top
surface and the user’s bot-
tom. Lift their leg slightly
and feel for their lowest
bony prominence. Then
lower their leg to a sitting
position. STEP 6: Turn valve coun-
terclockwise to let air out,
while keeping your hand
under the user’s lowest bony
prominence. Release air un-
til you can barely move your
finger tips - no more than
1 inch (2.5 cm) and no less
than 1/2 inch (1.5 cm). Turn
valve
clockwise to close.
NOTE: DO NOT sit on an improperly inflated cushion. Under-inflation or over-inflation of the
cushion reduces or eliminates the cushion’s benefits and could increase risk to skin and
other soft tissue. The cushion is most effective when there is 1/2 inch (1.5 cm) to 1 inch
(2.5 cm) of air between the user’s bottom and the seating surface.
