I had a quality control problem or there is  a mistake in the instructions. After assembly one of the small drawers would not go in. I discovered this was due to assymmetry in the placemenrt of the dowel holes in both  the central divider and the front to back brace which iacts as runners for the small drawers. I found that putting the brace in upside down relative to the instruction diagram made the problem go away. Of course, I had to take the back off and now I have splits running from some of the panel pin holes. But the back is against the wall so what the hell. If you buy this ignore what the instructions say and put the back on last.
