The two chair mats we bought work very well at our two work stations: my home office and my wife's sewing machine cabinet. They enable us to move our older office chairs between desks and work tables - over wall-to-wall carpet.
Product was not wrapped in any brown paper just rolled and it got a little scuffed up in shipping. Also the shipping “envelope” - the clear stick-on that held the packing slip was applied directly to the product and it required a fair bit of “goof-off” solvent to remove it (which I had to go out and buy). Would have been a 5 if not for the shipping.
