Specially engineered design allows workers to maintain a relaxed standing posture for an extended time. Contoured anti-fatigue design is ideal for computer work. The rear part (back area) of the mat features a 1-3/4" thick foam that absorbs the weight of the body through the heel, while the rest of the foot relaxes on a thinner foam. Perfect for working in front of a stand-up desk or service counter. Polyurethane foam core is laminated to a textured non-slip vinyl leatherette surface. FOB Shipping Point.
