I'm another that wouldn't be without one. Beds and floors are great until your back starts to hurt or they start to wriggle everywhere. I got rid of mine before we moved recently but wish I hadn't. I'll be buying another if we have another bub.
With DD her nursery was upstairs but the amount of times we changed her every day it was easier to have the change table in the family room with all the stuff we needed and all her clothes in the coffee table drawer lol.
