I needed to organize some items in my utility room, which is not  very large.  I looked and looked and then I read about this particular unit.  It arrived soon after ordering and took just a few minutes to assemble.  I recommend starting with the bottom shelf first to stabilize the other parts. You need no tools; things just snap together.  This unit was appealing because it had 5 shelves.  The size was just right because the space was limited.  I like being organized and this did the trick in my utility room.
