What can I say about a chair mat other than it is a must on carpet for easy movement. Mats is of good quality and should stand up against the daily workout I will give it.
For years couldn't talk my wife into using a chair mat and I smiled each time she labored to move her chair around at her desk. Recently we moved her office to a different location and I bought this low-priced good quality chair mat and put it at her desk. She rolls beautifully and thanks me profusely. Good construction with just enough flexibility. Not too thick and she can still see the carpet!
It works as advertised. But it is quite thin so there are temporary indentations where the chair leg or my footstep was. I don't think it hurts anything in the short term but it looks weird.
