The Varilite Evolution Wave CPW provides exceptional positioning of the lower extremities for enhanced sitting posture. The Lateral thigh supports position the lower extremities and prevent the unwanted abduction of the thighs. Medial thigh support provides the correct amount of abduction to prevent unwanted adduction of the thighs. The Wave CPW increases the weight-bearing load on the back of the thighs and decreases the load on the buttocks, without changing the seat-to-back angle. The closed-cell foam CPW will not absorb fluid and is resistant to bacteria.
The Evolution is available with a mesh or incontinence cover with breathable four-way-stretch material. Reticulated foam inside promotes air exchange and improves pressure distribution. The underside is a rugged nonslip material with hook and loop for added security. Evolution cover meets ISO 7176-16 ignition resistance standards for upholstered wheelchair components.
The cushion is also available in either standard or PSV (Pressure Setting Valve) depending on the user's choice. The PSV helps in taking the guesswork out of cushion adjustment and makes it automatic. The PSV works by sensing the amount of internal cushion pressure. As air is released, internal pressure decreases and the user are immersed in the cushion for effective pressure distribution.
