Read reviews that mention:
We put the top bunk together first. It was missing one of the main screw holes. We had to improvise and drill our own. It wasn’t such a big deal, just a bit annoying. The bed is very sturdy. Opened the middle bunk and it had NO SCREWS! Opened the bottom bunk thinking we’ll just do that one first. NO FREAKING SCREWS! So now we have two kids without beds. What a mess. How does this happen? No quality control.
