My wife and I assembled it in 3 hours. What made it easy was using a drill with a hex bit. If we didn't use the drill, it would've added another 60-90 minutes to assemble. We only had 1 bolt give us an issue. Other than that, we're glad we bought this metal bunk bed instead of the wood one. It's really solid and we're not afraid of it falling down during an earthquake. We also used 3 8 mattresses with it. It still has plenty of space of the side rails for our boys from rolling off. It's worth every penny.
Buy this metal bunk bed, not the wood ones.
