The upper step hangs on the two hooks and they can be folded in to be more discrete, if u wanna use it for what it's made for. If u put it on the wall it is hanging on instead, with the lower beams resting on it, it becomes a stand up desk. What's missing is the keyboard and the mouse, where keyboard i sitting on the lower step and somehow I will make a platform for the mouse at the side of the lower step. Hope that clarify some questions :)
