I think holes could be drilled differently so that there's only one way to fit some of the bits together, especially when the piece has to go a certain way. I had to take the tall shelf bracket apart and put it back together again after I realized that I'd reversed the end pieces and there was no way to put the horizontal supports for the work surface in.

It does what it says it does, and my kid is pleased with it, but it's DIY assembly furniture that's not all that well thought out.
