This is my second purchase of a Floortex may. I bought one about four years ago from Great Offer Stock for my home office. Recently, my husband decided to set up his home office and needed a floor mat to protect the carpet. I immediately ordered the one I have. My reason primarily is because this mat does not have the stinky, nasty, chemical odor many floor mats give off. Those chemicals are so unhealthy, and I don't want to introduce toxins into my home. I paid more for this mat than I would have had I been willing to buy one with toxins, but I'm willing to pay more to keep away the toxins. You won't go wrong with this mat.
