This entertainment wall unit is composed of TWO chests. The larger chest sits on top of the smaller lower chest. The lower and smaller chest is not especially heavy and can be moved around fairly easily. The top cabinet is pretty heavy, and its own weight keeps it firmly in place. It is possible to use these chests separately and you could place the top cabinet on the floor or better yet onto heavy duty casters. It was designed to use as one big wall unit, but you can use your imagination to create other options if you like. I am not the imagination police!
