Comfort King™ with Zedian™ sets a new standard in anti-fatigue mats. You can feel the Zedian™ difference the moment you step on a Comfort King™ mat. In fact, you'll feel 3 times as much "bounce" as vinyl foam - more than almost any other industrial mat. Comfort King™ slices replacement costs, too. Its amazing durability keeps it performing longer than vinyl sponge mats - approximately three times as long. Available in mat or roll form. 3/8" thick.
