Select pieces of furniture that have both wood and metal in the design. For example, you might choose a coffee table with a wooden top and metal legs. This way you can tie in the other pieces of furniture in your room that are made exclusively from one material.
Place objects of the opposite material on the other surface of furniture pieces. For example, if you have a solid wood bookshelf, choose a few decorative metal accents to place on the shelf. Likewise, if you have a metal accent table, select a wooden accent piece to place on top of the table.
Put metal knobs on solid wooden pieces of furniture, such as a cabinet or television stand. This lets you combine the two styles of furniture in a subtle way.
Arrange items in your room in a way that places a piece of solid metal furniture next to a solid wooden piece, and visa versa. Avoid placing all solid metal or wooden furniture pieces in one area of the room to ensure a balance of the styles throughout the space.
Select a wooden base for a lampshade, then purchase a faux-metal lampshade to tie together your two types of furniture. Set it on a shelf or table in your room.
Select wall art decorations that incorporate both wood and metal. Hang the pieces around the room to further incorporate the two types of material from the furniture.
