Was not rolled up as preview review said.  Came in between two sheets of cardboard stapled together and shipped flat, this is not an item that can be rolled.  It seems to be made of a good quality plastic, a previous buyer said theirs cracked, and I did note this, and that's why I specifically ordered this because the carpet I'm using it on is a flat carpet with no room for the heavy weight of my office chair to allow room for that to happen. Time will tell, but as for now, it seems to do what it says.
