A canopy bed lives or dies on labeling. The four posts often look identical but seat into specific corners, so getting organized before you touch a bolt saves you real time later.
Pro tip: Take a full photo of the assembled bed from each corner before disassembly, canopy bed geometry is the hardest bed style to reassemble from memory.
Watch out: Canopy bed posts are often longer than they look once removed, measure your truck and stairwell clearances before assuming they will fit standing up.
