As I said - Time will tell. It appears to have a quality no better than those selling for half the price.My previous pad cracked when used over a carpet & pad. It was half the price of this one.
The labels says that it is an economy mat for commercial carpeting as found in an office. If you try to use it on the type of carpeting found in a typical home the mat is too soft because the carpet is too thick. I am afraid that over time it will start to develop indentations from the chair wheels. It is good for saving a few dollars as the thicker mat was twice the price but you get what you pay for and need to match the mat with its intended use.
