One person can put this together but I will say that it'd be MUCH easier with two people. The tools they give you are workable but it's much easier with a drill and a hex bit. The instructions are pretty clean and all the pieces are labelled so there's very little doubt in whether you're doing things right or wrong. The hydraulic arms that hold the mattress up and open the storage are very strong and sturdy (one thing I was skeptical of when I bought the bed) so even if you have a heavy mattress this should have no problem. All in all I think it was pretty straightforward to put together, looks great, and is very very sturdy, would happily buy this again if I went back in time and had to decide again.
