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.
The mat is clear but it is thin and the wheels from my chair have created created indentations limiting the movement of the chair as early as with the first use.
Purchased this mat to protect the wood floor at my house. Works PERFECTLY. This is smooth on both sides so is gentle on the floor . . . the size is right for moving back and forth and side to side while never leaving the mat. Would definitely buy again.
