The size is great but this mat is not made for a plush carpet. I just put mine down yesterday and I already have dents and divots. If you have a plush carpet find a different product.
I'm worried about how well this will hold up. Only a couple of days and the impressions/divots from the chair wheels seem pretty significant. Delivery was fine. dimples that go into the carpet are far less hard and pointed than my previous mat. But the mat is much thinner than the previous one.
