Choosing a metal and wood bedroom set in a streamlined design is the easiest way to make your bedroom immediately and unequivocally industrial.
Other tricks involve introducing other pieces of furniture in the same style, maintaining a neutral color palette (e.g. white, black, and different shades of gray), including exposed brick walls and metal accents whenever possible, and using humbler items for a different and creative purpose, such as crates or vintage tea chests as nightstands or storage solutions.
