This was my first build. I modified the dimensions to fit a full sized bed and used 1x4's as the slats. Overall I am very happy with the outcome and learned a lot from the build. Of note these plans do not accommodate a box spring. This bed fits perfectly in my very small guest room and is very sturdy (and heavy!). I did not glue the corners for easier disasembly when I move.
This project took me a long time as I am a new builder. I would expect a more experienced builder could make the bed in a day.
