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.
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.
