Great carpet! Of all of them here, this is the only one I could find with a rim, and it comes with so many tiles for the price, so it's pretty roomy. I will say the molds come out which would normally be fine but I also have kids aged 7 and 5 who can't help but take them out all the time. I know that eventually they will be lost or broken and my rug will have holes of the wrong size.
