Put the crib together by myself in an hour and twenty minutes. I would recommend having two people put the crib together, but it is totally doable for one person. Directions were pretty straightforward. Just make sure you are looking at where the holes are in the diagram. I had to take the back rail off and turn it around so holes faced the back because I didn't pay close enough attention to the picture in the directions. But overall, the crib turned out very sturdy and passed the scrutiny of a first-time dad/mechanical engineer. My impression is that we will eventually need to replace this with a different bed before our child graduates high school, but I am very confident that we will get our money's worth out of this bed.
