I built this for my sons' room, boxes are IKEA, from $4 to $6 each, the frame built from Home Depot pine, about $80 total for the entire project, if I went with IKEA frame, it would be about $300 total since i would need to buy three smaller shelves. The best part: my son cleans up every night ( with a little help and encouragement,) and he is 4 years old. And he knows where everything is, small boxes for small toys, big boxes for stuff that does not fit into a small box. Not bad!
