This bed was delivered in 2 large (long) boxes. The assembly instructions are easy to follow for the most part - there is little narrative, and some of the symbols take a few minutes to decipher. The instructions indicated it would take 2 people 70 minutes to assemble. I was able to complete the job by myself in about 3.5 hours. It is not difficult at all, but as I mentioned, some of the instructions are a little hard to decipher, but it is very step by step and well thought out. My son loves the color and is very happy with his new bed.
