We were able to assemble it in one night, however it is really annoying that every screw must be done by the mini Allen wrench they give you. There were at least two screws that were impossible to fit into the allotted slots. suitable for kids... if they aren't going to play or toss too much on the top bunk. Makes me a little nervous that everything was put together with the Allen wrench. Ladder bar is also extremely uncomfortable on feet.
