Very complicated to set up, definitely need two persons to put together. Ladders are slippery so supervise small children. If you buy this bed, a regular size mattress is not recommended should be four to six inches in height or child will fall off. All in all with bruised and battered fingers and knuckles and time (took 2 Days by myself) I thought that they would make instructions with actual pictures so to avoid confusion. If you dod this make sure your read instructions carefully and have a lot of patience. Good Luck
