How is the VARILITE cushion adjusted properly?

A: 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.
