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.
For the price this floor mat performs. However I’m about 200 pounds and on California Berber carpeting. My chair makes 5 divots in the floor mat & then gets stuck so it doesn’t easily move. It’s better rated for low pile carpeting or accept its faults
