I put it together by myself and it was a bit challenging. I do recommend having a second person if possible, but I will say it’s not impossible to do it alone. 

The instructions weren’t very detailed, so I moved slowly to make sure I was really studying each piece.   The bottom drawer was missing a piece so I shoved it in there incorrectly until I get a new piece. Overall, I’m happy with this purchase. I laid on the mattress for a few mins and it was very comfy and the bed felt sturdy.  I think it took about 2.5-3 hrs to build, would have been less if I had someone helping me.
