I'm not good at assembling anything, directions or not, so the bed sat unopened for a month after I saw how many nuts and bolts came with the thing. Finally, a guy did it for me and it took him about an hour WITHOUT power tools and said it would take about 20 minutes with them.
When it was finished I noticed it was a little lower to the ground than I hoped but it wasn't a deal breaker. Also, I ran and threw my entire 6 foot body at full sped on the bed and it didn't even move - seems pretty sturdy so far. A little darker brown than I hoped but all in all great bed.
