Varilite Evolution Wave cushion is recommended for individuals with motor and neurological dysfunction due to spinal-cord injury, stroke, cerebral palsy, multiple sclerosis and traumatic brain injury. Evolution wave features a superior pressure distribution; positioning stability, comfort and simplicity that makes it the most popular wheelchair cushion.
Air & Foam floatation
Soft foam functions for the decubitus-sensitive area of the ITs; medium foam functions for the thigh trough, pelvic bucketing and pre-ischial bar; and firm foam functions for the perimeter and the medial thigh separator. Bonding evolution foam to coated fabric makes the cushion hold air.
Positioning supports
It improves the stability which is important for users with compromised sitting balance or who transfer frequently. Multi-stiffness foam provides support as the user is immersed in the cushion. Medial and lateral supports minimize internal & external lower extremity rotation. Pelvic bucketing and a pre-ischial ridge help maintain pelvic position, and thigh troughs promote a neutral femoral position.
Standard Valve for adjusting air volume
Sitting on a fully inflated cushion, the user opens the valve and releases air, closing the valve when sitting on approximately 1/2 inch of air and foam.
Pressure Setting Valve (PSV)
PSV works by sensing the amount of internal cushion pressure. As air is released, internal pressure decreases and the user is immersed in the cushion for effective pressure distribution. PSV is marked with three pre-set positions to provide the best range of immersion for most users.
Four-way stretch fabric
Evolution foam is bonded to four-way-stretch knit fabric for maximum conformity during immersion. The fabric is puncture and water resistant.
Cover
Evolution cushion is available with a mesh or incontinence cover with breathable four-way-stretch material. Incontinence cover wicks the moisture away from skin and protects cushion inside. Reticulated foam inside promotes air exchange and improves pressure distribution. The underside is a rugged nonslip material with hook and loop for added security.

Q: How do Varilte cushions work?
A: Air in a Varilite cushion supports the load, while foam keeps the air where it's needed and preserves the cushion shape. Learn more about the Varilite Air-Foam technology
Q: How is the 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 system instructions for more information.
Q: Why do some seat cushions have an indentation?
A: 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 detailed information
Q: Will a 16" x 18" cushion fit in a 17" x 18" chair?
A: No. Select the cushion that is 1" larger. For example if your wheelchair size is 17" x 18", select an 18" x 18" cushion. The cushion will accommodate the 1" size difference without affecting its performance.
Q: Are Varilite cushions available in custom sizes?
A: Varilite cushions are available in a wide range of widths and depths. Size selection is frequently updated to meet the needs of customers. Standard sizes often accommodate custom wheelchairs well. If you need a size that is not currently available, select the cushion that is 1" larger as explained in the above question.
Q: How do I maintain my Varilite seating system and back support?
A: We recommend that you leave the valve open and allow the 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.

Q: Is there any latex in Varilite cushions or covers?
