We bought one from same store is very good. But this one is not good after few use can see hollows. We have the same weight and using the same chair why this happened? Unfortunately we cannot find the receipt. we never think of will need to return this product. Can I reurn it and get the better one and pay the difference?
This was the only chairmat that was offered in my local store. That is the reason why I purchased it. I had just installed new carpeting and I didn't want my office chair to damage the carpet. This chairpad was basically a waste of money. It moves every time my chair moves at the desk. I have to constantly take the chair off the pad and move the pad back to where it is supposed to be.
Even though our carpet is not considered extra-high pile we bought this hoping that the thickness of the mat would keep my husband's chair from sinking into the mat. It works wonderfully.
