I had bought one of these years ago and now that I have been working from home for the past 7 mos. I wore it out. It had holes and cracks and was a little dangerous. I ordered the same mat and it came next day and I am again sliding easily and without danger
The plastic is very thin and I'm leaving marks with my chair after just a few days. Also it took a real effort to get the label off the mat I needed to use rubbing alcohol and "scrub."
