This is one of the best purchases I have ever made.  I've gone through so many hard plastic chair mats I was ready to give up.   The color and quality is wonderful.  I chose two of the dark cherry.   One for me and one for my husband.   The size works great in our offices and it's smooth rolling.   Now I have to find a much smaller one for my sewing center.   Carpeting is warm but hard to roll on.   These do the trick.   They are sectioned so they unfold easily and lay flat on the floor.  Just watch for pinching fingers in the sections as you unroll.
