The plastic floor mat is as advertised. It's working as a plastic mat that sits on top of a carpet and supports my wheeled work chair is supposed to work. Ask me in a few months or years if the mat is still in great shape or if like the last one I bought it had cracked so much that a piece of it in the middle had even broken out. (This mat might be a bit thicker than the last one. It cost a bit more than the last one. I guess you get what you pay for if you're lucky.)
