Quilter's Select mats have a thin layer of memory foam inside. They are almost slick to the touch. I have had my big one for about ten years and it still looks and feels like new. I usually have QS mat on top for small cuttings. I use the Martelli Roundabout for rotating. When that mat gets too used I will cut a QS mat to fit the roundtable. but the Martelli mat is holding up just fine. I haven't tried the Creative Grids mat yet. I may buy a small one and see how I like it.
