I will admit that the instructions directed you not to use power tools, but I used a power drill with the hex nut attachment and it saved me a lot of time. This was very easy to put together, but use another person to hold while you tighten and attach parts. This is a very sturdy and strong piece of furniture and this is from someone that has purchased many bunk beds. Additionally, the kids absolutely love their new bunk bed from the color to building it!
