Read reviews that mention:
It took me about an hour to assemble by myself. One thing to note, the screws needed to attach the bottom frame and sideboards are already in the boards so don't spend time looking for them and cussing that they are not in the pack of screws. They are there.
Everything fit together with a solid fit. Slats seem to be of very good quality.
For the price this is a great bed frame. Would be worth it for $100 more.
