Varilite FAQ's

Air in a Varilite cushion supports the load, while foam keeps the air where it’s needed and preserves the cushion shape. 

For both Pressure Setting Valve (PSV) and standard valves, begin with the cushion fully inflated and valve closed. Transfer onto the cushion.

For a PSV, turn the valve clockwise until the pre-determined number appears in the indicator window. Air will escape until the valve automatically shuts off (approximately 10-15 seconds). Once the valve has shut off the release of air, close the valve by turning it clockwise. See PSV Operating Instructions for more information.

For a standard valve, slowly turn the valve counterclockwise to release the air. Listen for a change in pitch and close the valve by turning clockwise. Air level is determined by the amount of support or stability needed by the user, comfort, and activity level. See Seating Systems instructions for more information.

The cushion is designed to indent in the sacral-ischial area. The soft, less firm foam of the sacral-ischial area, by design, exerts less “push back” on the cushion fabric than the surrounding firmer foam. See Sacral-Ischial Foam Indentation Explanation for more information.

No. Select the cushion that is 1” larger. For example if you wheelchair seat size is 17” x 18”, select an 18 x 18 cushion. The cushion will accommodate the 1” size difference without affecting its performance.

We recommend that you leave the valve open and allow your VARILITE cushion to fully inflate overnight at least once a week to maintain optimal cushion performance and foam integrity. Check your cushion’s inflation level daily to ensure optimal seating and positioning.
