Perfect size for my small carpeted home office. Needed to let it air out for a couple days on the porch due to the strong plastic smell. Works well now that it's in place.
It's not a bad chair mat but it is a little thin and as such quickly develops impressions where the chair wheels set. Afterwards the chair doesn't roll as freely. However I'm sure a heavier one would likely cost more.
This one has little gripper teeth on the bottom and it lies flat no problems. The former one had no teeth and it bunched up all the time. This one’s a keeper.
Worked great once I was able to unroll it. To get it soft and ply able I put it out on the deck in the sun for and hour. Size is right and saves the rug
