It took around 4-5 hours assembling the bed (size full) solo. Some of the pieces did not align with the holes, so I spent time finding the perfect spot so that the nails would go in. One issue I found is that a piece of the bed was damaged. It had a missing nail holder (not sure what it’s called), so I could not put the nail in. Other than that, the bed looks exactly like it is online, so I’m glad for that.
