My 4 year old grandson and I assembled this easily.  It is sturdy and fits perfectly in the closet.  My grandson was so excited about his new storage unit and immediately transferred his train sets and toys from the bags and boxes we had been using.  When we were done, he just sat in front of the open closet door smiling.  I am extremely happy with this purchase and WAYFAIR in general.  I have purchased many things from WAYFAIR and have been delighted with all the products, shipping (no cost) and prices.
