• VARILITE cushions and covers always shall be used together. The cushion cover is an essential part of the seating system for optimal
performance. Using the cushion without its cover increases the risk of flammability. When the cushion and cover are used together, all
VARILITE seating systems have met the flammability requirements of ISO 8191-1 and ISO 7176-16. The Evolution, Meridian, and Zoid
additionally meet the requirements of BS EN 1021-1 and BS EN 1021-2.
• If your wheelchair is equipped with a fabric upholstered seating surface, ensure that it is adjusted properly to prevent hammocking and
unintended postural effects.
Product Detail and Specifications
Note: If you received an Evolution, Solo, or Stratus cushion, it is possible to remove the cushion from the cover and flip the

Materials used in the construction of VARILITE seating systems: VARILITE does not use latex or phthalates anywhere in
the construction of our products.
CUSHION SETUP AND ADJUSTMENT
1. Remove the cushion from the packaging and open the valve by turning it counter-clockwise, allowing the cushion to fully
inflate. You should not be sitting on the cushion at this time.
2. Close the valve by turning it clockwise.
Adjusting air level in a cushion equipped with a PSV™ (Pressure Sensing Valve):
1. Begin with the cushion on the wheelchair, fully inflated with the valve closed.
2. Transfer onto the cushion.
3. Open the valve by turning it counterclockwise until the pre-determined position number ("1" , "2" , or "3") appears in
the indicator window. Unless otherwise indicated by your clinician, use position "2" . Air will escape until the valve
automatically shuts off (approximately 10-15 seconds). Fig. A
4. Once the valve has shut off the release of air, close the valve by turning it clockwise. This prevents additional release
of air due to weight shifts, transfers, propulsion, etc.
The PSV is located on the right side of VARILITE cushions. For operation from the left side, remove the cushion from the
cover and rotate the PSV 180°. To prevent damage to the valve body, use a 1/2 in. open-end wrench, open the valve all
the way, and place the wrench on the flat shoulders at the base of the valve body. Fig. B

3. Turn the valve counterclockwise to open the valve and release air. You want to sink down about 1 to 2 inches (2.5 to
5 cm). Fig. C

2.5 cm) of air and foam between the ischial tuberosities and the seating surface. Always follow your clinician's
recommendations for proper cushion adjustment.
