Unfortunately, one of the pre-drilled holes did not accommodate the barrel nut, requiring my husband to have to drill the pew-drilled hole deeper. Also, during assembly, a side slat slid off, cracking the piece of the crib that had the pre-drilled bolt hole. Again, requiring wood glue and a clamp to put it together. Of note the 4 corner slats do not connect flush with the crib sides. Uncertain if this is by design or the location of the pre-drilled holes.
