I like when everything is there and easy to put together. When you put it together you need to take your time and follow the directions. If it does not seem right I found I needed to review the instructions again. I and the cats really love it. If I could have you change anything it would be the screws of the swing that screw right though the above floor and leaves four sharp points protruding. I just covered the points. If you had stops on the screws so that did not happen that would be nice.
