These chair mats will withstand the stampeding of rhinos. Well maybe. But they definitely endure perpetual rough usage by our employees. Our company only buys this brand of chair mat and they last for years. The only reason we bought this one is because the one it replaced was 8 years old. It's great only for carpeted flooring the spikes underneath grip the ground firmly ensuring that it never moves. After 5 years of use my own personal chair mat is starting to curl up on one of the edges and I've stubbed my shoe and tripped on it a few times. But after 5 years I still can't complain because this thing doesn't even have a crack in it! Wonderful.
