I've had this item in my house for a week. It still has bumps that have not flattened. I also have it on carpet. The little teeth on the bottom do not stay in the carpet. My chair is on wheels and I've had to move the mat every 2 days to put it back in place. Because it moves the chair wheels get stuck if I move forward too much I can't get the chair to roll back.
This mat worked well on my carpet. It stays in place and I can move around in my office chair without fear of the mat shifting. Very well satisfied and I would recommend this item.
It’s not as thick as I expected so with how plush my carpet is my chair doesn’t roll as easily. BUT it’s better than being stuck in the carpet and not able to move. I’m satisfied.
I’m disappointed with this mat. In only a week deep grooves have formed where my chair wheels rest. So now I cannot roll the chair around my desk smoothly I have to actually pick up a chair leg to roll it out of its rut. Think I need to return this.
