The bed took a couple of hours to assemble but there was nothing extremely complicated.  The directions were easy to follow.  The bed seems sturdy, although it is wobbly.  We haven't attached it to the wall yet, but expecting that this will help this matter.  The rungs on the ladder hurt my daughter's feet so we are trying to think of options to make climbing up and down a more pleasant experience.  Otherwise, seems like good construction and a solid bed.
