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 Notrax® exclusive UniFusion™ technology. This virtually eliminates the possibility of de-lamination. All Notrax® laminate floor mats come standard with RedStop™, a uniquely engineered non-slip backing technology that eliminates the slipping and sliding of floor mats on smooth surface flooring such as tile, wood, marble, and treated concrete.
