This product needs to be packaged differently. When the matt flattens before you put in on the carpet it gets folded and it is difficult to remove those waves in the plastic. I had to return a mat for that reason
This mat is much smaller than the one we had before. It is much too soft and gets pockets where the chair rolls over it. The edges also curl. Wish I had purchased another one like I had before. It was harder and larger. This one was a waste of money for me. I would only recommend using this on a concrete or no pile carpet.
