I bought this specifically for my carpet because it said it can be used for carpet/padding up to 1” in thickness. The grooves on the underside of this mat are about 1/4” in depth which provides no real relief to the carpet it’s on. The mat itself indents along with the carpet when I’m using my chair on it.
Arrived in one day. It doesn't slide and the thicker mil made a big difference. My chair is not on rollers and it leaves very slight dents in the plastic which do not last long. I have not seen this mat in retail stores so I'm glad I bought it on line.
What else can I say about an overprices piece of plastic laying under my chair? It serves its purpose--protects my carpet--and is actually very boring. I wish it did some tricks. =P
I purposely waited over a year to review this product in order to determine how it stood up to daily use. Some plastics will break down and crack. I'm happy to say this product shows no signs of wear and tear yet. No cracking.
