Get all the best traits of air and foam the Air/Foam blends from VARILITE, like the Varilite Evolution Wheelchair Cushion with a Standard Valve.
Air plays the part of a fluid and displaces beneath the load, but if it is not confined properly, the air offers no valuable support. On the flip side, the Varilite Evolution Wheelchair Cushion's foam, gives you all the support and conformation you need, and works like a spring compressing under load. To get a reliable level of support, the foam has to be firm so that you don't bottom out. The more you need your foam to push back, the firmer is needs to be. That is where the adjustability of the Varilite Evolution Wheelchair Cushion comes in.
The Varilite Evolution Wheelchair Cushion's air is the support, and the foam keeps the air where it is needed, preserves the cushion shape, and prevents bottoming out. Because air supports most of the load, low-density soft foam can be used. This results in a lightweight cushion with less “push back” or interface pressure.
Immersion is what makes the Varilite Evolution Wheelchair Cushion's air-foam floatation effective. VARILITE air-foam cushions use multi-stiffness foams to provide support and conformation under different areas of the user. A valve releases air to immerse the user in the foam, and the different foams conform to the user’s shape. As immersion increases, the load is distributed over more of the cushion’s surface area and pressure points are reduced.
Optimal pressure distribution is achieved when the load is distributed over the largest area.
