I use this product at home in a computer room. It has meet my expectations with two exceptions: the mat slides out of position and divots are easily created by the chair.
I placed my computer in a "closet" that is directly behind (when the door is open to the hallway)a door. There is beige carpet in the room and the mat is placed in such a way that the offset is placed under the door and the larger portio is where my chair is. Only problem with the setup is-I am in the way of the door opening the whole way when I use my computer!!
