I used a drill with an 'allen wrench' shaped bit and a screwdriver with the same bit to finish tightening everything, and it went well.  It's as incredibly cute in person as it is in the picture.  Thumb's up all the way.  On the negative-ish side, the ball tops are a kinda cheap plastic (but only noticed when putting them on, then they blend in just fine).  The main complaint I would have is that I wish there were more slats, that they were closer together, and that they weren't so narrow.  You will need a mattress with a built in spring so you don't feel the bars through the mattress.  We put a 12" Hybrid WayFair Mattress on it and my daughter loves it!!  (We also bought a black laced canopy curtain and led lights around top.  Thank you WayFair!!!   (and no, I don't work here, lol)
