What is the difference between a buffet table and a sideboard?

Buffet tables and sideboards are both types of cabinet furniture. Though often used as a synonym for “sideboard,” a buffet technically possesses a tiered or shelved superstructure for displaying decorative kitchenware. The term derives from buffet à deux corps, a piece which is seen mostly in French Provincial furniture. A sideboard is a side-table with cabinet doors that is used for serving, most often in a dining room. In form, a credenza has much in common with a sideboard (it's not uncommon to find a sideboard in a foyer, however). Find a wide range of mid-century modern buffets and sideboards on 1stDibs.
