Comfort Deck is a premier, heavy-duty anti-fatigue mat. Its substantial design offers exceptional overall performance including comfort, and drainage for safe, firm footing in heavy use areas. In addition, its high quality vinyl compound resists the effects of many industrial fluids and solvents. Comfort Deck's incredibly popular stock size mats are permanently heat-sealed together and feature wide, safety-colored ramps on three sides for trip-proof access. With interlocks on two adjacent sides, the 12" x 12" PVC tiles easily connect to form virtually any size or shape. This allows us to frequently customize Comfort Deck in large and unusual configurations. These mats are also permanently heat-sealed together.
