I liked best the young girl who helped me. She knew what was looking for so I don't wear out the carpet in my room. I forgot her name but she was a black woman. And she carried what I bought to my car.
I've tried different chair mats before on my carpet but they always start pulling up on the sides making it easy to trip over. I've had this mat for about a month and have not had a single issue with it. It's easy to roll over with my chair but does sometimes budge every now and then.
We returned a previous pad by another company because the chair sunk into the pad. No problem here. The chair moves easily. We used the pad on a carpet with soft padding. We only wish that we had ordered a larger pad but that was our mistake. This one will do fine.
