We ordered the exact size we needed. It took about two days to install: one day for it to lay out and remove some of the folds, and the next day to install. My husband did it all by himself in one day. It came out fantastic. Yes, it does get a little hot after the sun has been on it, but the dogs love the heat. It is so easy to clean up dog poo, leaves, and sticks. So far, we love the grass. It has been worth every penny.
