GSMART TileTop is the entry-level offering within this popular family of marbleized anti-fatigue mats…the "Good" version of our Good-Better-Best. The marble top surface is a chemical-resistant and durable PVC that is lightly textured [almost smooth], supple to the touch, and very easy to clean. But the huge advantage that SMART has over everything else in its class is the 100% recycled Urethane composite sponge! SMART sponge is amazingly resilient, earth-friendly, and super economical. It provides users with a winning combination of durability, value, and relief underfoot that sets a new standard for marbleized matting…all while easing one’s environmental impact. SMART TileTop is a win-win that every working team can embrace.
