The bed came folded in a box. We took the bed out of the box and laid it upside down, per the instructions, then screwed the legs to the bed. We turned it over and put the mattress on top. (The mattress did not come with the bed, we purchased it separately.) So, no tools, but be warned, it is extremely heavy. But my husband is 74 and managed to do it all by himself with very little help from me, other than staying out of his way! I hope this helps.
