Gel-Foam Ischial Steps have anti-hammocking, anti-skid bottoms to eliminate the “slingseat sag,” while providing a stable base of support. The wedge shape inhibits forward leaning and sacral sitting.
These cushions have:
- A convex-shaped bottom of high-resiliency (HR) polyurethane to eliminate sling-seat sag.
- A layer of quadragel to help reduce shear forces, to assist in redistributing pressure and to inhibit heat buildup.
- An optional layer of Gel-Infused Visco Elastic (G.I.V.E.). This layer provides shock absorption, body molding, pressure redistribution and comfort.
- A thin top layer of HR Foam.
- An anti-skid bottom.
