This was rolled up and held closed by tape. When the tape came off I had a VERY difficult time getting the sticky part off of the mat even with a product that should take it off. Also it is not the quality of the mat I replaced. It is thinner.
Our office chair would not roll on it easily it was very hard to do. Made immediate dents and afraid with longtime use it would crack. We plan to return it.
It is the perfect size I was looking for. Stay in place and no middle seam which is great. A little soft on carpet but gets the job done. Chair rolls easily.
