The floor mat is doing what it should: it protects the floor in front of the wheels of an office chair. Anyone who has seen me, what these roles can wreak so everything takes a very early age to such a floor mat. Very good, I find that you can order the mat in many different sizes. So everyone can find the right mat for his room. It is important that you subtract the blue protective foil before use. This is not easy and also connected with some noise. The purpose of this film I did not quite understand. Scratching does the mat later anyway. In addition, you should make sure to put the protective mat with the right (smooth) face down on the ground. Conclusion: strong buy recommendation
