I have to remain neutral on this item as only time will tell if it holds up under average use. I have tried more expensive mats that have cracked within a year. Even got different wheels for my chair but still had cracking. At least I am not out big bucks as it is disposable at this price.
This was purchased to go in front of my wife's sewing machine which is in a spare bedroom we use as her sewing room/home office. I got it home unrooled and put it into place. Looks great and works great.
The mat is thick and made of quality plastic that's pliable. Unrolls and flattens within a minute or two under the weight of a chair. My chair easily maneuvers over the surface without the mat shifting and the lip provides good foot traction for getting up or moving forward or back. And you can back up in your chair without going off the mat which made it the perfect size for me. A winner!
