I was looking for a mat to protect my carpet. This one was the only one small enough to fit and I love it. I don't fight with my chair anymore either because it rolls much smoother on the mat than it did before.
Im really disappointed with this mat. It rolls on the carpet with the movements with my chair. I was hoping that the back will hold the mat on place instead I have to move it daily at the end of my day o I will have a bump when it reach my desk legs
