I can’t say enough good things about this product. A great option for adding storage in my walk-in closet without breaking the bank. It’s very easy to assemble. It took me about an hour to put together the nine cubes. They are very sturdy and could easily contain books and shoes although I just need them for clothing. I would recommend to the manufacturer to sell the cubes in packages of six as I could add more cubes but ordering another nine cubes would be too many.
