The shelf need some assembly, which we must have missed in the details when ordering. The back 2 panels didn't fit right, there was a noticeable gap. The holes are pre-drilled and if you put the back together as the hole suggest there is a gap that runs down the center of the back, so when you open the doors you see a gap in the back panel. We ended up not using the pre-drilled holes that the two back panels wouldn't have a gap.
