The mat's knobbies on the bottom are just right but it didn't flatten out all the way yet. I have had it a week. Took 2 days just to get the thing to unroll and then I had to point a heater at it. Maybe this summer it will finish flattening....
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.
The matt looks like it does in the photos. The size was as expected. However it is so soft that my chair makes indentions so I sort of get stuck in a spot.
The mat is nice but not very thick. If this is for a home office you might check it out in the store first or get a thicker mat. It seems like it will last but my chair sinks into it when I sit so I have to push myself out of little holes when I want to move.
The mat is exactly what we needed to protect the carpet under our office chair. It is a great size good quality and stays in position. It was delivered quickly!
