Total build time for one person was just under 45min. I was impressed with how easy the assembly instructions are. A ratchet was included to tighten the bolts which was a nice touch. 

Bed is super sturdy and all of the connections lined up perfectly. The nice thing about the metal frame is that there is very little flex. The bed is super low to the ground, I would rather it be up 6” higher, but the quality makes up for it.
