Bubble Trax is a unique high performance anti-fatigue floor mat with a bubble-top surface design providing extreme 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.
