The Varilite Evolution PSV Wave Cushion is Superior pressure distribution, positioning stability, comfort and simplicity have made the Evolution our most popular wheelchair cushion. The VARILITE’s innovative PSV (Pressure Setting Valve) we’ve made the Evolution PSV even better, taking the guesswork out of cushion adjustment. With the VARILITE Evolution PSV, you can set and forget your cushion to meet your individual needs. Positioning Bases Positioning bases improve stability to help users with compromised sitting balance or who transfer frequently. Multi-stiffness foam provides support when you're immersed in the cushion. Medial and lateral supports minimize internal and external lower extremity rotation. Pelvic bucketing and a pre-ischial ridge help maintain pelvic position, and thigh troughs promote a neutral femoral position. Positioning Wedge The Wedge accessory is included in the package of each Evolution. It's a reversible, modifiable foam wedge that reduces the seat-to-back angle, which increases the weight-bearing load on the back of the thighs and decreases the load on the buttocks. The 2 inch (5 cm) tapered wedge trims easily for custom fitting to meet individual needs. Why By a Varilite Evolution PSV Wave Bariatric Cushion?
