This bed was for my 6 year old. It took me 5 hours to put together by myself with a little help from my son. The reason it took so long was the tools that were given were poor quality. Most if the instructions were easy to follow. It was hard to tighten everything because the tools kept slipping out of my hands and the bed was wobbly. When I used my own tools I was able to tighten everything and it seems very sturdy and my son loves it.
