Bubble Trax® Grande is a unique high performance anti-fatigue floor mat with a bubble top surface design and is a full ONE-INCH thick providing the ultimate in ergonomic comfort and durability. Bubble Trax® combines a heavy-duty vinyl top surface with a dense sponge backing utilizing the Notrax® exclusive UniFusion bonding process. The resulting finished product is virtually a single piece eliminating any possibility of de-lamination. Bubble Trax® uses RedStop non-slip backing, a uniquely engineered technology that eliminates the slipping and sliding of Notrax® floor mats on all types of smooth floor surfaces such as vinyl composite tile, painted or epoxy coated concrete, vinyl sheet flooring, carpet, and ceramic tile.
