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.
My pile is 1" thick I asked for a mat that the wheels wouldn't sink into. I'm 190 pounds. This mat didn't do it. Disappointed it will be return tomorrow AM.
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
