I like his mat it’s serving it’s purpose by allowing my chair more movement at my desk. I took away a star because it came rolled up which meant I had to give it a few days with 2 heavy objects laying on each side to it it to not curl under while laying it down. I also took away a star because it doesn’t allow much movement on my carpet. If I sit in a spot too long my wheels get stuck and I can move unless I stand.
I like this mat. It protects my carpet from the black marks my chair was making on it. I just wish it would stay in one place when I roll around in my office chair. Although I have to adjust once a day it serves the purpose I bought it for.
