FAQ's For Wheelchair Cushions
Which cushion is best for sitting long periods, pain relief, preventing pressure sores?
the ROHO family of products, the high profile (4" cells) line of
products are going to offer the most immersion (sinking in) into the
cushion. This greater immersion will increase the force (weight)
redistribution of the client thus decreasing peek pressures and
improving comfort, decreasing pain and preventing pressure ulcers.
Through this immersion, you are better able to redistribute (equalize)
the weight (force) of the client onto their thighs, greater trochanters
(hips), and the ischial tuberosities (buttocks). Through immersion into
the 4" cells, a ROHO cushion aims to reduce the extrinsic risk factors
of peak pressures, shear and friction, and microclimate in pressure
ulcer development; however, it is important to assess the client
individually for other risk factors including, but not limited to,
nutrition, circulation, and previous history of pressure ulcers which NO
cushion is able to affectively address.
Can I place an incontinence pad, towel, drawl sheet or hoyer lift sling over top a ROHO cushion and/or a ROHO mattress?
anything that you place over a ROHO cushion or mattress, actually any
cushion or mattress, can interfere with the effectiveness. A ROHO
cushion/mattress works by increasing the contact area of the individual
when they immerse (sink) into the product thus redistributing the force
so there is limited peek pressures at one specific landmark. When
anything is placed between an individual and the cushion/mattress,
surface tension is increased and thus they have a more difficult time
immersing (sinking) into the cushion/mattress effectively.
since each and every individual needs to be treated individually and a
plan of care needs to be considered based upon that individual’s
specific circumstances, we also realize that other needs like
incontinence, safety during transfers etc. need to be considered. A
licensed healthcare professional should weigh the risks of placing a
pad, towel or Hoyer lift sling, thus reducing the effectiveness of the
cushion/mattress, versus the risk of not placing these items.
an incontinence pad or drawl sheet is required while the individual is
sitting on the cushion or lying on the mattress, it is our
recommendation that the least amount of layers are used and these
pads/sheets are put overtop the cushion/mattress in a fashion where they
are very loose and NOT tight.
the removal of a Hoyer lift sling from underneath a patient, who was
transferred onto the cushion, is going to cause increased shear and
friction, which may be detrimental to an individual’s skin, a licensed
healthcare professional should weigh the risks of keeping the client on
the cushion WITH the sling in place, versus removing the sling.
Can I use my ROHO cushion without the cover?
is true that anything that you place over a ROHO cushion, actually any
cushion can interfere with the effectiveness. A ROHO cushion works by
increasing the contact area of the individual when they immerse (sink)
into the product thus redistributing the force so there is limited peek
pressures at one specific landmark. When anything is placed between an
individual and the cushion, even a ROHO cover, surface tension is
increased and thus they have a more difficult time immersing (sinking)
into the cushion effectively. However, ROHO has gone to great lengths to
provide a cover, which still allows immersion with the least amount of
surface tension created. Mr. Graebe, the inventor of the ROHO cushion,
from a scientific standpoint, would recommend a ROHO cushion actually be
used without the cover.
previously stated, our covers are made to be used so that there is
little if any interference with pressure distribution when they are
being used. When other things are used instead of our stretchable,
breathable cover, like a pillowcase, a sheet, a quilted chuck, or
another wheelchair cushion cover, there is less effectiveness of the
cushion due to increase tension. Bottom line, the person has less
immersion and envelopment of the body, thus reducing the pressure
bottom line . . . can a ROHO cushion be used without the cover?
Absolutely. Particularly if there is no risk that the cells may become
caught in something. Should the cushion be used with something other
than the cover it comes with? NO, it will significantly reduce the
benefits of the cushion.
How can I choose the right cushion?
the assistance of a clinical professional who can assess your clinical
requirements. In many countries, occupational and physiotherapists have
the expertise; however, your personal physician can advise and offer
How often should the ROHO DRY FLOATATION Cushion be checked for proper inflation?
hand check should be performed daily with the patient's ADLs
(Activities of Daily Living). The entire adjustment procedure needs only
to be done when necessary. It only takes a few seconds.
If I currently have pressure ulcers, can I sit on my ROHO DRY FLOATATION cushion?
It is appropriate for individuals with a stage 1, 2 or 3 ulcer to sit
directly on a ROHO DRY FLOATATION cushion provided they, or their
caregiver, monitor the wound frequently. In conjunction with proper care
and nutrition, it is proven that an ulcer can heal on a ROHO cushion.
Due to our unique ability to redistribute pressure, enhance blood flow,
and decrease edema, we are thereby able to enhance healing. A stage 4
ulcer usually requires surgery and presents numerous complications for
Does neoprene rubber promote heat buildup?
The ROHO DRY FLOATATION cushions are air filled. Air has a very low
specific heat making it a poor conductor of heat (less transfer of heat
than with water or gel). Less transfer of heat from patient to cushion
results in increased energy levels of the end-users.
I need a very stable cushion. Which one should I choose?
have a variety of models which offer positioning and stability.
Examples include the SELECT Family line, which includes the QUADTRO®
SELECT® and the CONTOUR SELECT™ cushion, the nexus® SPIRIT® cushion and
the new HARMONY™ cushion. A clinician trained in seating can assist you
in choosing the appropriate model for your needs.
How can I get literature on the ROHO product line?

would be glad to send you information.
How long does a ROHO DRY FLOATATION cushion last?
average, three to five years. The amount of wear and tear an individual
user subjects their cushion to will effect the life of the cushion.
Using the cover supplied with the cushion will extend the life of your
cushion. ROHO, Inc. offers a two-year limited warranty on the ROHO DRY
FLOATATION cushion product line and a three-year limited warranty on the
SELECT cushion product line. In addition, each cushion is supplied with

Do the ROHO cushions only prevent pressure ulcers, or can the patient actually have an existing pressure ulcer?
range of ROHO DRY FLOATATION cushions were designed to either prevent
or heal. Both cushions and mattresses can and should be used in
conjunction with proper care and nutrition to enhance the healing
process over a period of time. (A clinician should assess the intrinsic
and extrinsic factors of skin breakdown particular to you, to determine
what effect a ROHO cushion might have.)
do you mean by "Handle your ROHO DRY FLOATATION Cushion with care?" In
other words, what are the DO's and DO NOT's for a ROHO DRY FLOATATION
·Pull or attempt to carry the cushion by the cells, valve, or ISOFLO® Memory Control™ valve.
·Expose the cushion to petroleum based solutions (e.g., lanolin).
·Sit on cushion with sharp items in your pockets.
·Follow the operating and cleaning instructions.
If using a ROHO cushion, can I sit longer than two hours, or do I still need to have some movement anyway (pressure reliefs)?
Many users increase their sitting times dramatically (e.g., 16 hours).
ROHO suggests you follow the routine of pressure relief procedures
recommended to you by your clinician. By consistently monitoring your
skin, you may be able to determine what period of time must pass before
you begin to experience redness.
What is the weight limit of the ROHO DRY FLOATATION cushion?
the cushion size will cause a limit. Therefore, it is imperative that
each individual receive the proper size for his or her stature and
chair. Custom cushions are also available.
Do you offer custom cushions, and how do I order one?
We do offer custom cushions. The advice of a rehab specialist would be
most helpful in designing a specific custom cushion. Our Customer
Service department also has a staff available to assist you in custom
orders. Simply call, fax or e-mail ROHO with your questions.
Do I need a rigid base underneath the cushion, or is a sling seat okay to use with the ROHO cushion?
suggests all of our seating products be used with a solid seat insert,
unless the wheelchair sling is designed not to hammock or sag over time.
ROHO offers two types of solid inserts which can be inserted between
the cushion and cover for convenient transportation.
Can I tie down cells to create a no pressure area?
the past, there have been many proponents of tying down cells to create
no pressure areas under the seated surface. However, unless medically
necessary, we recommend not tying down cells, as the cushion performs
best when distributing pressure over the entire contact area.
a no contact area is incorporated into a cushion, a high pressure
perimeter surrounding the no contact area is created. This variance in
pressure between the perimeter and no contact area tends to cause shear,
deformity and trauma to the tissue, thus increasing risk of ischemia.
In addition, there is the possibility for pooling of interstitial fluids
(edema) at the no contact area reducing efficient cellular nutrient
transfer. Enhancing blood flow and nutrient transfer is essential and
the DRY FLOATATION® cushion allows for this healing process to occur. If
you tie down cells, you run the risk of delaying healing or actually
increasing the size of a wound.
What about cushion toxicity?
people ask or talk about LATEX TOXICITY what they are really asking or
talking about is a severe allergic reaction to proteins found in Natural
Rubber. Natural Rubber comes from the sap, a white milky fluid (latex),
of the Hevea brasilienis or rubber tree. The proteins are Mother
Nature’s way of keeping the sap from coagulating as it moves through the
tree carrying moisture and nutrients from roots to leaves and back. All
products made from Natural Rubber contain some amount of these
proteins. The amount depends on how the latex was processed and how well
the products made from it were leached and washed. Not only are rubber
like products, gloves, condoms, catheters and tubing made from Natural
Rubber, but, also adhesives and sponge foams.
everybody will have some kind of a reaction to these proteins.
Depending on the number of times exposed and the duration of the
exposure the reaction can be anything from a mild dermatological rash to
anaphylactic shock. Certain groups of people appear to be more
susceptible to developing anaphylaxis. Healthcare workers for example,
may develop severe dermatological reactions because of the daily
repeated exposure and Myelodysplasia (spina bifida) patients seem to be
particularly at risk, especially under anesthesia.
Incorporated products are manufactured from man-made materials. The
cushions themselves are made of Neoprene, a synthetic rubber material
that contains no protein, the covers are made of Nylon, Lycra,
Polyurethane, and Polyvinyl chloride, and pumps are made of
discussing specific allergy problems with healthcare workers we should
be careful not to forget that a very small percentage of the population
will have a reaction to contact with our cushions. People develop
hypersensitivity to all sorts of things. Some people develop hives and
severe itching when they come into contact with wool clothing. Others
develop reactions to detergents and soaps or citrus fruits. Because the
cushion is made from a chemical polymer and contains other chemicals
used to produce a cure and render it resistive to UV light and the
effects of ozone etc. means that a few rare individuals will have a
dermatological allergy reaction to our product. This can be a serious
problem but it should not be confused with the protein toxicity
associated with Natural Rubber.
Can I returen my ROHO Cushion?
Yes. You can return the cushion within 30 days if it is in NEW
condition. Due to hygenic reasons, a Roho Cushion cannot be returned
if it is used. To ensure that you ordered the correct size, we
recommend that you first try the cushion without taking the cover out of
the sealed package. If it is the wrong the size, please let our
customer service team know immediately and we will do an exchange.
Note: Exchanges incur actual freight charges, which is the shipping
charge to ship the cushion back to us and then the shipping cost to
resend the correct size. Depending on where you live the actual
shipping charges are usually around a total of $30.00.
My cushion has developed a leak and it is still under warranty. How do I get it serviced?
If you have a ROHO cushion that is
in need of service, call the Warranty Service Department at
Information needed when calling in:
- Cushion's serial Number
- Date of Purchase
- Description of the Defect
Once you call in, a Warranty Service Representative will walk you through the process of getting your product serviced.
Whats the difference between between High, Low, and Mid Profile Cushions?
ROHO manufactures 3 heights
of cushions; a High Profile, which has 4” tall air cells, a Mid Profile
cushion with 3” tall air cells, and a Low Profile that has 2.5” tall
purpose of a ROHO cushion is to decrease the amount of pressure on the
sitting area through a patented technology of interconnected neoprene
air cells that increase and decrease in air volume to match an
individual’s contours. This dry flotation technology facilitates blood
flow to the sitting area and assists in the healing of ischemic ulcers
I generally recommend High Profile
Cushions for first time users or for individuals with current pressure
sores (or a history of pressure sores) due to its ability to maintain
proper pressure relief even if slightly underinflated. This gives the
client or caregiver more room for error without compromising the
client’s skin integrity by “bottoming out” in the cushion. The drawback
to the High Profile Cushion is that its 4” tall air cells could make you
feel like you are sitting up too high, therefore giving you a sense of
Profile Cushion with its 2.5” tall air cells offers a lower center of
gravity than the High Profile Cushion, which provides an increased sense
of stability. The Low Profile Cushion is appropriate for active users
that would be frequently transferring on and off of the cushion. The
lower cell heights also allow easier transferring and propulsion if
being used on a manual wheelchair. The drawback is decreased room for
error in regards to maintaining proper inflation. Simply put, you must
have the ability monitor how much air is in their cushion to prevent
Profile cushion is halfway between a High and Low Profile. The Mid
offers you an option for both moderate protection and stability.
Whats the difference between a Quadtro Select Cushion and a Single Compartment?
The basic difference between a
Quadtro Select and a standard ROHO is an extra valve located on the
front of the Quadtro cushion that splits the cushion into four equal
compartments. The valve can either be opened to allow airflow
throughout the entire cushion or it can be closed to control airflow to
the four specific quadrants. This allows the client to customize the
amount of air in each chamber. When the valve is open, air flows freely
between quadrants and performs like a standard ROHO. The drawback is
having an extra metal and plastic valve on the front of the cushion that
some customers find to be cumbersome. It is an excellent cushion if
you require the ability to adjust air volume in each quadrant for
positioning needs and contouring to your body.
needs require different heights and styles, but assessing your specific
uses and abilities will help guide you to the proper selection.
