I thought this will be ok since my apartment unit has a commercial type of carpet the cheap quality. Based on the product description this chairmat is great for commercial carpets and not really suited for thick and high-end quality type of carpet. After only a few days of use it has already deep dents coming from the casters of my chair. It's probably just a matter of time that I will be seeing holes on the chairmat. Well I only paid [$] and it's just about the right price anyway.
