No one would believe this shoe tower was not part of the original closet system.  It's perfect - sturdy, well balanced, and attractive.  The cabinet, for which the shelves must be put together and affixed to the sides, is in in two separate sections, top and bottom.  My husband constructed the unit on his own - he's very handy - and, the only time he needed his trusty assistant (me) was in joining the top and bottom portions together.  That would have been a challenge for one person to accomplish because it is tall and they must be fitted together (and he's a tall guy).  So, a two-person team would be recommended for that phase of the project.  I am so delighted with this piece of furniture, and highly recommend it to enhance your closet or room.
