You have to make your own "makeshift" elastic to put it together to stay on the bed. It did come with the elastic pieces but I don't have time to make and assemble my own cover. It is also like a headband. This does not cover the entire box spring, it only covers the outside edges. I was beyond disappointed in this product.

It was just perfect. We didn’t have to take off the mattress. It was very easy to just put it around the box spring!

Easy to put on and provides a finished look to the bedding.

This thing is great quality and really helped hide the dark blue foundation!
