I’m extremely disappointed in the quality of this so called “Anti fatigue” floor mat.  The writing is good.  The color is good, but, for the purpose for which it’s meant, this mat is way too thin.  It should be fluffier.  There is no difference in standing on it, than standing on bare, hard ceramic tiles. I have problems with my legs and back. This is not the product to help me. I should request a refund.
