Did not want to spend the money but the carpet needed the protection as I scoot between 2 computers back and forth. I was hesitant to get one because I also hop up a lot to the printer etc and I did not want the chair to slip out from under me. So far its been just what I needed. I think I move arond enough that the chair dents will be evenly distributed but it is the econony one so it is on the thin side.
