Took a couple hours for me to assemble it. Instructions did have a couple places where the number didn’t match the picture of the part but it was easy enough to figure out. Structure seems to be very stable with good materials. Extra screws were supplied in case some got misplaced. I assembled it with the Allen key provided but it would be much quicker if you have power tools with the same head. Overall I am very pleased with the assembly and the bed itself.
