Frequently Asked Questions

These are a few of the queries that we frequently answer. If you have additional questions about your cushion or mattress, please contact our customer care department.

 

Which cushion is best for sitting long periods, pain relief and preventing pressure ulcers?

The 4-inch cells of our High Profile line of products (HIGH PROFILE Dual Compartment, HIGH PROFILE Single Compartment and QUADTRO SELECT High Profile cushions) offer the most immersion. This ability to sink into the cushion increases weight distribution, which will decrease peak pressures, improve comfort, decrease pain and prevent pressure ulcers. These products help redistribute your weight onto your thighs, hips (trochanters) and buttocks (ischial tuberosities). While immersion aims to reduce extrinsic risk factors of peak pressures, shear and friction, and microclimate in pressure ulcer development, it is important to assess other risk factors including, but not limited to, nutrition, circulation and a history of pressure ulcers, which no cushion is able to effectively address.

Can I place an incontinence pad, towel, draw sheet or Hoyer lift sling over a ROHO® cushion or mattress?

Anything you place over a ROHO cushion or mattress — or any cushion or mattress — can interfere with its effectiveness. ROHO cushions and mattresses increase the contact area when you sink into them, redistributing the weight so there are limited peak pressures. When anything is placed between you and the cushion or mattress, surface tension is increased and you will have a more difficult time effectively sinking into the cushion or mattress.

We also realize that your individual 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 sling versus the risk of not employing these items.

If a pad, towel or draw sheet is required, we recommend that you use the fewest layers possible. Pads or sheets should lay very loose over the cushion or mattress, not tight.

If removing a Hoyer lift sling is going to increase shear and friction, which may be detrimental to skin, a licensed healthcare professional should weigh the risks of keeping the sling in place versus removing it.

Can I use my ROHO cushion without a cover?

It’s true that anything that you place over a ROHO cushion — or any cushion — can interfere with its effectiveness. ROHO cushions work by increasing the contact area when you sink into the product, redistributing weight so there are limited peak pressures. Anything placed between you and the cushion, even a ROHO cover, increases surface tension and makes it more difficult to effectively sink into the cushion. ROHO has gone to great lengths to provide covers that allow immersion with the least amount of surface tension created. From a scientific standpoint, ROHO cushion inventor Robert Graebe would recommend a ROHO cushion be used without the cover.

Our covers are made so that there is little, if any, interference with pressure distribution. When other products are used instead of our stretchable, breathable cover, surface tension increases and the cushion is less effective.

Bottom line: Can a ROHO cushion be used without a cover? Absolutely, particularly if there is no risk that the cells will be caught in something. Should the cushion be used with something other than ROHO covers? No.

How can I choose the right cushion?

Seek a clinical professional who can assess your requirements. In many countries, occupational and physiotherapists have the expertise to help. Your personal physician can advise you and offer referrals.

How often should DRY FLOATATION® cushions be checked for proper inflation?

The hand check should be performed daily with your activities of daily living — it only takes a few seconds. The entire adjustment procedure only needs to be done when necessary.

If I have pressure ulcers, can I sit on my DRY FLOATATION cushion?

Yes, DRY FLOATATION cushions and mattresses are designed to both prevent and heal pressure ulcers. If you have a Stage 1, 2 or 3 ulcer, you can sit directly on a DRY FLOATATION cushion provided you (or a caregiver) frequently monitor the wound. Along with proper care and nutrition, it is proven that an ulcer can heal on a ROHO cushion. Our cushions have a unique ability to redistribute pressure, enhance blood flow and decrease edema, which all enhance healing. A Stage 4 ulcer usually requires surgery and presents additional complications.

Does neoprene rubber promote heat buildup?

No. DRY FLOATATION cushions are air filled. Air has a very low specific heat, making it a poor conductor. (There is less transfer of heat with air than with water or gel.)

I need a very stable cushion. Which one should I choose?

Several of our cushions offer positioning and stability, including the QUADTRO SELECT®, the CONTOUR SELECT®, the nexus SPIRIT® and the HARMONY® cushions. A clinician trained in seating can help you choose the appropriate model for your needs.

Can I get literature on the ROHO product line?

Of course. To receive literature in the United States or Canada, please call 1-800-851-3449 or fax 1-888-551-3449. To receive literature outside of the United States and Canada, please call 618-277-9150 or fax 618-227-6518. You also can send an email to our help desk.

How long does a DRY FLOATATION® cushion last?

On average, three to five years. It’s no surprise that wear and tear affects the life of the cushion; using the cover supplied with your cushion will extend its life. DRY FLOATATION cushions have a two year limited warranty, and Select cushions have a three year limited warranty. Each cushion also is equipped with a patch kit.

What makes ROHO DRY FLOATATION cushions better than other cushions?

Durability. Reduction of shear and friction on your skin. Adjustability. Proven performance over time. Learn more about DRY FLOATATION technology.

My cushion says “handle with care.” What does that mean?

Do:

  • Follow the operating and cleaning instructions.

Don’t:

  • Pull or attempt to carry the cushion by the cells, valve or ISOFLO Memory Control® unit.
  • Expose the cushion to petroleum-based solutions, like lanolin.
  • Sit on the cushion with sharp objects in your pockets.

Can I sit on my ROHO cushion for more than two hours? Or do I still need to have some movement or pressure reliefs?

Many individuals dramatically increase their sitting times, up to 16 hours. Follow the pressure relief procedures recommended 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 for DRY FLOATATION cushions?

The cushion is only limited by its size, which is why it is imperative that you receive the proper size for your stature and chair. Consult your clinician for sizing help. Custom cushions also are available.

Do you offer custom cushions? How do I order one?

We do! Advice from a rehab specialist is most helpful in designing a custom cushion. Our customer care department also is available to help you with custom orders. Call, fax or email our customer care department with your questions.

Do I need a rigid base under my cushion, or is a sling seat OK?

We recommend all of our seating products be used with a solid seat insert unless the wheelchair sling is designed to not sag or hammock over time. We offer two types of solid inserts, which can be placed between the cushion and its cover for convenient transportation.

Can I tie down cells to create a no-pressure area?

Unless medically necessary, we recommend cells are not tied down. The cushions perform best when pressure is distributed over all of the contact area. Creating a no-contact area also creates a high-pressure perimeter around the no-contact area. This pressure variance tends to cause shear, deformity and trauma to the tissue, increasing the risk of ischemia. It’s also possible interstitial fluids edema will pool at the no-contact area, reducing efficient cellular nutrient transfer. Enhancing blood flow and nutrient transfer are essential, and DRY FLOATATION cushions allow this healing process to occur. If you tie down cells, you run the risk of delaying healing or increasing the size of a wound.

Should I worry about cushion toxicity?

When people ask or talk about latex toxicity, what they’re really talking about is a severe allergic reaction to proteins found in natural rubber. Natural rubber comes from the sap (a white, milky fluid) of the Hevea brasiliensis, or rubber tree. The proteins are Mother Nature’s way of keeping the sap from coagulating as it carries moisture and nutrients from the 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 were leached and washed. Almost everyone has some kind of reaction to these proteins. Depending on the frequency and duration of exposure, the reaction can be anything from a mild dermatological rash to anaphylactic shock.

ROHO products are manufactured from man-made materials. Our cushions are made of neoprene, a synthetic rubber material that contains no natural rubber proteins. Our covers are made of nylon, Lycra, polyurethane and polyvinyl chloride. Our pumps are made of polypropylene.

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 develop hives and severe itching when they come into contact with wool clothing. Others develop reactions to certain detergents, 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, effects of ozone, etc., a few 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.
