Needs to be thicker. It is thin enough that if my chair stays in one place for more than a few minutes the casters sink down and the chair will not roll easily.
I was concerned due to the price being so much less than others but I was more than pleasantly surprised! Its a great mat works very well and was a great price like a 3rd of the other brands
Display was incomplete. Sales representative wen to back and brought out this one. We would have preferred a thicker plastic. Chair wheels sink into the plastic but otherwise it works fine.
