The whole assembly with trundle took me about 1 - 1.5 hours to put together by myself. When installing the slats on the main frame, the instructions just say to use a screwdriver, but there were no pre-drilled holes for the screws. I used a power drill, which worked just fine and went much quicker anyway. The bed looks just like it does in the picture, and I am pleased with this purchase overall. Note: it arrives in about 7 or 8 separate, large boxes.
