This is a good mat and the price was right. But even on low plush carpeting it is a bit too soft. after sitting a while in one place the wheels tend to sink into the grooves making it harder to push away from the desk. I probably should have gotten a harder surfaced mat to place under my desk chair.
I received the mat and was very very disappointed. I was not like my old one. My old one was thicker and more sturdy. Yours was very flimsy and very hard for the chair to roll on. I am very displeased to say the least.
