Easy to assemble, but definitely needs two people. The ladder hurts to climb for adults and bigger kids, but it's not unbearable. Littler kids have no problems at all. I like that it comes with a ladder for each side. I was specifically looking for a bunk bed that had a ladder on the foot/head, not the side. This definitely fits the bill. Two adults can lay on the full bunk bed comfortably with it still feeling very sturdy.
