The kit covers the front of the crib and the two sides. It is easy to tie on, and stays tied despite the skill of our 1 year old. He loves to eat the crib, thus his nickname "The Goat". The material is soft, super durable and easy to throw in the wash. It has a vinyl backing so that his drool does not soak down to the wood, which is perfect. I love that it protects his teeth as well. I wish I had thought to put this on before my child damaged my handcrafted heirloom crib, but I am a first time mommy, and you live and learn. Great product, I tell all of my prego friends to get one, and I have ordered another one for my pregnant sister in law. Shipped super fast too.
