The Gel-Foam concept is a combination of four (4) substrates:
A convex-shaped bottom of high-resiliency (HR) polyurethane to eliminate the hammocking sling-seat sag, while providing a stable base of support.
A middle layer of Quadragel to help reduce shear forces, to assist in redistributing pressure and to inhibit heat buildup.
A layer of “Gel-Infused Visco Elastic” (G.I.V.E.) with “Micro-Gel” beads This layer provides shock absorption, body molding, pressure redistribution and comfort.
A thin top layer of HR Foam.
