I had been looking for a BLACK cube like storage shelf for my daughter's room. Most things are black/brown or espresso and just wouldn't work. This fits her little canvas bins perfectly and has tall enough spaces for her barbie closets and other large toys. We have it set up horizontally in her room so that we can use the top for additional items-right now it holds books with book ends.
The only down side is when I did the top, there was one area that wouldn't tighten to become flush, but it's not a problem. I just wish I could figure it out so that there's not a gap!
