ROHO HARMONY Overlay Cushion Operation Manual
Intended Use
The ROHO®HARMONY®Overlay Cushion (HARMONY Overlay) is an adjustable, air-filled,
segmented-design, multi-purpose seating support surface intended to conform to an
individual’s seated shape to provide skin/soft tissue protection on a cushioned surface
(contoured or planar), including wheelchairs with captain’s seats, geriatric chairs, office
chairs, motor vehicle seats, or airplane seats. There is a weight limit of 275 lbs. (125 kg),
and the cushion must be properly sized to the individual.
ROHO, Inc. recommends evaluation by a clinician who is experienced in seating,
positioning and mobility to determine whether the cushion is appropriate for the
individual.
ROHO medical products are intended to be part of an overall care regimen. ROHO, Inc.
recommends that a clinician make product recommendations based upon an evaluation
of the individual’s medical and therapeutic needs and overall condition.
Warnings
• Skin/soft tissue breakdown can occur due to a number of factors, which vary by
individual. Check skin frequently, at least once a day. Redness, bruising, or darker
areas (when compared to normal skin) may indicate the beginning of soft tissue
breakdown and may need to be addressed. If there is any discoloration to skin/soft
tissue, STOP USE immediately. If the discoloration does not disappear within 30
minutes after disuse, immediately consult a healthcare professional.
• The cushion and the cover MUST be compatible sizes and MUST be used as directed
in this manual. IF THEY ARE NOT: 1) The benefits provided by the cushion may be
reduced or eliminated, increasing the risk to skin or to other soft tissue, and 2) the
individual may become unstable and vulnerable to falling.
• DO NOT use your cushion on top of, or in conjunction with, any other products or
materials, except as indicated in this manual. Doing so may cause the individual to
become unstable and vulnerable to falling.
• DO NOT use this cushion as a water flotation device (e.g. a Life Preserver). It will
NOT support you in water.
• If you are unable to perform any tasks described in this manual, seek assistance.
Cautions
• DO NOT use a pump, cover or a repair kit other than those provided by ROHO, Inc. Doing
so may void your product’s warranty.
• DO NOT modify the cushion or any components. Doing so may result in damage to the
product and will void the warranty.
• Changes in altitude may require adjustment to your cushion.
• Keep the cushion away from sharp objects.

Cushion Adjustment
1. Place the cushion in the wheelchair with the air cells
facing up and the non-skid surface of the cover facing
down. The individual should not sit on the cushion.
2. Slide the rubber nozzle of the hand pump over the
inflation valve. Turn the nozzle to open the inflation
valve, and inflate until all of the air cells feel firm.
3. Remove the hand pump.
4. Do not close the inflation valve.
5. Allow air to escape from the inflation
valve. Listen (or place your hand in front
of the inflation valve) to confirm that air
is no longer coming out of the cushion.
Close the inflation valve.
6. The individual should sit in the chair in their usual
position. Confirm that the boniest prominences are
supported by the air cells.
7. Slide your hand between the air cells and the
individual. Lift the leg slightly and feel for the
lowest bony prominence, and then lower the leg to a
sitting position. You should barely be able to move
your fingertips.
8. The recommended distance between the individual
and the contoured foam base is ½”- 1”. If the
cushion has too much air or not enough air, open the
valve, adjust as needed, and then close the valve.
Important Safety Information
• Check inflation frequently, at least once a day!
• DO NOT use an under-inflated cushion or an over-inflated cushion because the product
benefits will be reduced or eliminated, resulting in an increased risk to skin and other
soft tissue. If the cushion does not appear to be holding air, or if you are not able to
inflate or deflate the cushion, see TroubleshooTing. Immediately contact your clinical
caregiver, distributor, or ROHO, Inc. if the problem persists.
• When possible, use the hook or loop fasteners to further secure the cushion to the
seating surface.

Cover Removal and Replacement
Inspect the cover for damage and replace if necessary.
Keeping a cover on your cushion will help to protect the cushion components. A cover will
also help to keep the air cells together, which may aid in slide board transfers.
Cover Removal: Unzip the cover and remove it from the cushion.
Cover Replacement: Unzip the cover. With the air cells facing up, insert the cushion into
the cover. Close the zipper. If hook fastener strips were removed prior to washing, replace
the strips.
Troubleshooting
For additional assistance, contact your clinical caregiver, distributor, or ROHO, Inc.
Not Holding Air - Inspect for inflation valve and hose damage. Confirm that the
inflation valve is completely closed. Look for holes in the cushion. If very small holes or
no holes are visible, follow the instructions in the Repair Kit provided with your product.
For inflation valve or hose damage, or for large holes or leaks in the cushion, see the
ROHO Limited Warranty supplement provided with your product, or contact Customer
Care.
Not Able To Inflate or Deflate Cushion - Confirm that the inflation valve is open.
Inspect the inflation valve and hose for damage.
Uncomfortable / Unstable - Confirm that:
- the cushion is not over-inflated (See Cushion Adjustment.)
- the air cells and the top of the cover are facing up.
- the cushion is centered beneath the individual.
- the cushion is properly sized to the individual and the wheelchair.
Allow the individual at least one hour to adjust to the cushion.
The Cushion Slides on the Wheelchair - Make sure the non-skid bottom of the
cushion cover is facing down. Use directional labels on the cushion and on the cover
to orient the cushion. Use hook and loop fasteners to further secure the cushion to the
wheelchair.
