I’’ve been using this mat on a hard floor (not carpet) for several weeks now. It’s Great!! I’ve tested this with 2 different chairs and it hasn’t slid or moved at all. it’s clear and has a slightly textured on top so it doesn’t glare as much as I thought it would. It’s a great purchase!
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.
