The mat would be great for someone who doesn't weigh much and isn't using a heavy-duty office chair. My husband(weighs about 180 lbs + chair weight) tried it for two days and the mat was starting to get dents in the parts where the chair wheels were so over time it would just be a hassle to move the chair out of those dents in the mat.
This mat is a smaller size. The teeth really hold to the carpet. My chair fits exactly the way it should. My feet even have room. I do not wear shoes when working from home.
Cons: - Does not stay put on my carpet - constantly has to be moved back into place - Huge indentations from my office chair in the mat constantly Pros: - Cheap
