The VARILITE Zoid™ is the low-profile cushion of choice for active wheelchair users at moderate risk of tissue breakdown.
Therapists recommend the Zoid for individuals who need a low profile, tapered cushion without a medial thigh separator. Athletes value its lightweight design and vibration impact dampening. On the court. On the track. On the trail.
VARILITE Air-Foam Floatation, coupled with multi-stiffness foam, delivers superior pressure distribution. Functional areas of the Zoid are created by three types of foam: soft foam for the decubitus-sensitive area of the Its; medium foam for the thigh trough and pelvic bucketing; and firm foam for the perimeter.
Tapered design, low profile, stability, comfort, and simplicity have made the Zoid the preferred performance cushion for active wheelchair users. Ultralightweight, its tapered shape makes it ideal for rigid chairs, and its cover is designed to protect the thighs of users with tight hamstrings or who tuck their legs under their chair.
Air and Foam floatation
Functional areas of the cushion are created by three types of foam: soft foam for the decubitus-sensitive area of the Its; medium foam for main seat support area; and firm foam for the perimeter.
Bonding Zoid foam to coated fabric makes the cushion hold air. A valve releases air to immerse the user in the foam, the foam conforms to the user, and the user’s weight is distributed over the surface of the cushion.
Independent research has shown VARILITE air-foam floatation to be the #1 impact and vibration dampening technology (RESNA 2000).
Positioning Supports
Extra-firm, beveled foam increases lateral stability and sitting balance, while a large ischial pan protects the pelvis in both anterior and posterior pelvic tilt positions. There’s no medial thigh separator, so lower extremities can drift naturally into midline for better fit in a tapered chair.
Four-way-stretch
Fabric Two types of fabric are bonded to Zoid foam. Four-way-stretch knit is used on the top for maximum conformity during immersion, and nylon fabric is used on the bottom for added strength and durability. Both fabrics are puncture and water resistant.
Cover
Stylish and functional. Four-way-stretch mesh fabric wraps around the front edge to eliminate seams. Reticulated foam inside promotes air exchange and improves pressure distribution. The underside is a rugged nonslip material with hook and loop for added security. Zoid cover meets ISO 7176-16 ignition resistance standards for upholstered wheelchair components. Machine washable.”

How do VARILITE cushions work?
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
How is the cushion adjusted properly?
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.
Why do some seat cushions have an indentation?
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.
Will a 16” x 18” cushion fit in a 17” x 18” chair?
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.
Are VARILITE cushions available in custom sizes?
VARILITE cushions are available in a wide range of widths and depths. We frequently update our size selection to meet the needs of our customers. We welcome your size suggestions for planning future product sizes. Customers tell us that our standard sizes often accommodate customer wheelchairs well. If you need a size that is not currently available, 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.
How do I maintain my VARILITE seating system and back support?
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.
What is the weight capacity for VARILITE seat cushions?
Is there any latex in VARILITE cushions or covers?
No.
