I purchased this as I had two youngsters joining us for the holidays. We purchased the floor pad as well. The combination was great to contain two 1 year old little boys in my not so child proof home. It comes out of the box already assembled, and be manipulated to different sizes to fit your space. There was a little door to walk in and out easily, and kept all the toys in one area. When it came time to fold up, it easily folds and goes back into the box until the next visit. (Pay attention to the configuration when you unbox. The two larger sections are on the outside and the smaller panels fold up between).
