This is the second time ordering this particular mat only this one is a little smaller. I love how smooth it lays and how easy it is to roll on. Without the lip there is no tripping hazzard. Great quality laid down flat from the start. The only down-side to this mat is that it lasted me for about three or four years before it started cracking and breaking but my mat gets a lot of use.The price is good for the quality you are getting so you can afford to replace it every four years or so.
The whole best thing was that it was delivered the very next day!! I had expected to wait a week.While I liked my old mat better [seemed to anchor in the rug pile better] old mat was getting rips in it -- after 5 years. Got help anchoring it under computer desk and my chair is sliding on it real well.
