At first look, the floormat looked like it would be an excellent option.  Within a week, that opinion changed.  My floormat would constantly shift under my chair.  It is obvious that the teeth were not designed appropriately to keep the mat in place.  This lead to scuffing up the furniture around the mat.  After 1 yr and 6 months, the mat started cracking and breaking up.  I attempted to make use of their limited lifetime warranty.  They agreed to send me a replacement for my mat if I paid a $30 shipping charge.  Let me see.  I have a product that did not live up to expectations.  With the dissatisfaction that I have with the mat already, I get the pleasure of having to pay more money for a product that I am already not satisfied with.  Conclusion: I recommend staying as far away from this product and company as possible.
