It took my niece (who was helping me) and I almost 5 hours to just put the bottom bunk and trundle together because none of the pieces had decent holes for the screws to go in so we had to make the holes ourselves. Havent even put the top bunk together yet. My mother and daughter havent had a chance to actually sleep on it yet because we are waiting for the in-the-box mattresses to decompress. As of right now though, I give it 4 stars.
