The Evolution cushion is designed and constructed for users at high risk of tissue breakdown and who have moderate positioning needs.

Caregivers in sub-acute and long-term care facilities like the simplicity and tissue integrity management the Evolution cushion offers, particularly for individuals with wound care issues.

It is an air-foam floatation cushion made by bonding open-cell foam to airtight, puncture resistant stretch knit fabric. The airtight seal allows the self-inflating/deflating mechanism to function by the simple turn of the valve. By releasing air, the user becomes immersed in the foam, which increases the surface area supported. The foam provides the user with support and stability, while the air provides excellent pressure distribution.

The Evolution cushion can support up to 340 kg, making it an ideal cushion for the bariatric wheelchair user. Two common accessories used with the Evolution are the modifiable closed-cell foam wedge and the contoured positioning wedge. This can be effective in reducing the seat-to-back angle, and in doing so increase the weight bearing load on the back of the thighs and decrease the load on the buttocks, as well as providing additional positioning. It comes standard with an incontinent cover. The underside of the cover is a rugged non-slip material with Velcro for added security.

How will I know which wheelchair cushion or backrest is right for me and my needs?

Occupational Therapists will help you decide what is required from these products; and can also source these items. There is a vast array of different products and brands in New Zealand, with each product having different pros and cons. Registered professionals are able to guide clients through their options and help short-list the appropriate products.

When selecting a wheelchair cushion and/or backrest for a family member the following factors need to be considered:

  • Does the user have a history of pressure areas or sores?
  • How long will the user be sitting in the wheelchair for each day?
  • Are there any incontinence issues?
  • Does the user have any significant postural challenges e.g. slumps to one side?

Cushions offer benefits such as comfort, pressure relief and can contribute to optimum positioning.  Cushions can be manufactured from a range of different materials; where some require more maintenance than others. 

Can I trial different backrests and wheelchair cushions?

Yes; these items can be trialed, provided there is a request from a therapist. The trial process is very important to determine whether the selected product is suitable. Generally, the trial time frames are two weeks and therapists will set the product up to meet your needs. Adjustments can be made to ensure comfort throughout the trial.

How do I wash my cushion or back cover?

Please refer to the manufacturer specific washing instructions. Each cover has washing instructions within the product manual, so we recommend you read this.

  • For Ottobock covers, turn the cover inside out, zip closed, and wash in warm water in a regular machine cycle. Regular detergent is OK, please do not use bleach. Air dry flat
  • For Varilite covers, turn the cover inside out, zip closed, and wash in warm water in a regular machine cycle. Regular detergent is OK, please do not use bleach. Air dry flat
  • For Ride Design covers, turn the cover inside out, zip closed, and wash in warm water in a regular machine cycle. Regular detergent is OK, please do not use bleach. Air dry flat
  • For Axiom covers, turn the cover inside out, zip closed, and wash in warm water. Regular detergent is OK, please do not use bleach. Air dry flat.
  • For ADI covers, hand wash the foam pad cover with mild, soapy water or detergent and let dry.
  • It is not recommend that any covers go into the tumble dryer.

Can I sit on the wheelchair cushion without its cover on it, while the cover is being washed?

The cover is an important part of the cushion and the two parts are designed to work as a team. It is not recommended to use the cushion without the cover.

How long will a cushion or backrest last?

Wheelchair cushions and backrests are designed to last for at least five years. Appropriate care and maintenance are very important for ensuring longevity and reliability of the cushion.

How do I adjust a Varilite cushion to contour to me?

With the cushion fully inflated and valve closed, transfer onto the cushion and open the valve by turning counter clockwise. Listen for a change in pitch and close the valve.

Are wheelchair backs easily removable so that I can fold up my wheelchair and take it in the car?

Yes. There is a large array of styles and brands of wheelchair, and backrests have different types of mounting brackets. Most of these simply unclip and allow the backrest to be pulled off, it simply slots back into place and is then secured using the clips once assembly is required again.

What is a wheelchair seat rigidiser and why is it used?

A seat rigidiser provides a firm foundation under the wheelchair cushion, enhancing stability and posture support.

Can a seat rigidiser be used with any type of wheelchair cushion?

Most rigidisers are compatible with various cushion types, but compatibility should be checked for each specific model.

How does a seat rigidiser affect the overall comfort of a wheelchair?

It evenly distributes pressure, reducing discomfort and the risk of sores, while improving seating alignment.
