I put the entire thing together, by myself, in 2.5 hours. It was not as difficult as some have mentioned. One step (maybe step 11 or 14?) was reversed for me. But that was the only little hiccup. If you read ahead in the instruction manual, you can figure out quickly what you need to do. My only complain about the bed is that the drawers are not build into the bed, the merely hook into a hole with a bolt in the drawer. Otherwise, for $425 it was a good buy for a guest bed.
