After using the mat for a little while there are ruts where the wheels of my chair have set for a little while. Then the chair is stuck and it’s hard to roll out of the rut. I don’t believe this has anything to do with my carpet.
I've had the mat for less than a week and already it shows dents from chair's roller wheels. Disappointed in "thin" quality. Replaced previous desk mat from Stapes that lasted for several years. A shame they downgraded the quality -- and the size.
does show chair wheel indentations but does not yet seem to hinder chair rolling easy to roll back on to mat if you roll off. generally pretty satisfied. would recommend.
Resorting to zoom Zumba classes made me concerned about wearing out my carpet in that area. This floor mat solved the problem while still showing the pattern of my carpet. I've decided to order another to give me a wider range for steps. Perfect!
