During sitting, it has been estimated that as much as 75% of body weight is taken through the sacral area, which can lead to significant pressure damage. Prevasse is a proven aid in the prevention of pressure ulceration for all patients including those assessed as high risk and for the treatment of existing category 1 and 2 pressure ulcers.1

It's Like Floating on Air

The Prevasse may be cleaned and reused for multiple patient uses:

  • Transportable and lightweight solution for static chairs

  • Transportable and lightweight solution for compatible general purpose wheelchairs where securing in place with the strap is possible

  • Easy to clean for multi-patient use

  • Suitable for both Acute and Homecare settings

  1. Insert the pump nozzle firmly into the cushion valve

  2. Inflate cushion with sufficient air to ensure the user’s weight is supported, redistributed and user is comfortable. DO NOT OVER INFLATE.

  3. Close the valve when finished and invert valve into cushion to prevent potential impact which results in value leaking.

Check device regularly to ensure proper inflation level. It may be necessary to add or remove air for just the right comfort level, but always ensure the patient is fully supported on the cushion. If deterioration in skin condition is noted, cease use and seek clinical advice.


Keep away from sharp objects, pets, babies and small children, and avoid sources of heat (including lighted cigarettes). Product does not contain latex.

Please note, Prevasse is not suitable for the following:

  • Persons weighing in excess of 139kg

  • Persons with unstable spinal fracture

  • Where body shape is such that the person cannot be fully supported by the cushion
