I've put quite a few manufactured wood pieces of furniture together. This had to be the worst. See pics. As you can see, the shelves are supposed to fit in these slots. They didn't which made for quite an interesting few hours. We did our best with what we had and it leaned BAD. We did a lot of pushing, pulling, unscrewing,  rescrewing until it sat straight. I thought the doors would be hard to install because I've had problems with other furniture. They were actually cake compared to the main unit itself. It came with a few chips missing but they aren't really visible. After all the adjusting and swearing, it's not that bad lol. Looks nice and holds what I wanted it to.
