To all of the reviewers who said this pad wasn't thick enough I apologize for not believing you. You are 100% correct this doesn't work any better then their other protectors. This protector is being used on burber style carpet and after less than 5 minutes of sitting on it you have wheel pockets from the chair you are sitting in. God help you if you want to move the chair and once you do move it you roll right back into the wheel pockets that you were trying to get out of. The chair that is being used came from Staples it is their leather managers chair($259) not one of their cheap ones. Bottom line don't waste your money beleive use when we say these protector aren't thick enough.
I am using this in my office over carpet. The product is too light weight and pliable. Consequently the chair rollers form indentations in the mat making it difficult to move the chair.
