Factory carts make a popular coffee table that adds a rustic, wood touch to the room. You can add a clear coat of polyurethane to bring out the character of the wood, and rub down the metal parts with oil. Look for carts with labels or writing on them to add interest.
Crates, trunks, suitcases, and boxes are great choices for coffee tables, especially since you gain storage with the pieces that have lids. You can stack multiple pieces for height, or add legs to smaller pieces like crates to make them even with the couch.
You can also use parts of trunks or suitcases to make your table, such as this trunk lid with legs attached:
