As some of the other reviewers mentioned the slick material does slide a little on a tile floor but it is only occasional. The material is flexible enough to flex over the uneven tile but thick enough to smooth out the bumps between tiles. I am happy and it works well for my home office.
Very nice product. It makes moving my chair back and forth a breeze because I have carpeting and the chair wouldn't move. I would recommend it to anyone.
The mat moves around constancy relocating it. It's thin the wheels on my chair sink into it. I would not recommend it I was debating to return it but the 15 day return passed.
It's a good mat and I'm sure it will do what it's supposed to do i.e. protect the carpet from being beat up by my chair. After only about a week or so of use the wheels on my chair are putting some serious divots into it. I'm using it on a berber carpet with not a lot of pile. Don't know if that would make a difference. I'm thinking I should have got a hard mat instead of this soft one.
