Super easy construction and lots of added support so I’m hoping to get to use this for years to come! Built it alone and finished before my daughter finished her movie. Everything is nicely labeled so made early organization quite simple. 
One thing I will say is when putting the metal base on, don’t tighten down the bolts on the bars until after you’ve attached it. Bolt down the straight bars first so they sit flush, tighten down the metal pieces, and then bolt on the rectangular pieces.
