After carefully reading the instructions and following word for word, this queen size complete cover was easy to put on. Because it zips up completely you have to move the matress all ther way off the base. You need 2 people to help do this project. The queen size had extra room so it fit very well. The top is almost like a suede material and feels lovely on your skin if you choose to not use a sheet on top. The sides are made of repellent material which I like in case one of the kids spill something while eating. I also like the fact that its made with a bacterial repellent. This is wonderful with a house that includes multiple children. We have decided to purchase for the remaining matresses in our household.
