A cabinet is a box-shaped piece of furniture with doors or drawers for storing miscellaneous items. Some cabinets are stand alone while others are built into a wall or are attached to it like a medicine cabinet. Cabinets are typically made of wood or, now increasingly, of synthetic materials. Commercial grade cabinets, which differ in the materials used, are called casework. Cabinets usually have one or more doors on the front, which are mounted with door hardware, and occasionally a lock. Many cabinets have doors and drawers or only drawers. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens.?

The term “cabinet” is now generally understood as medium to large size piece of furniture dedicated to storage, which is accessed by doors and may consist of many small drawers or open shelving. The earliest cabinets, however, were specifically designed for the storage of papers and other valuables. They were also used as places for writing, which led eventually to a distinct type called: "Secretaries" or "Bureauxs". Cabinets are thought to have been the result from the realization that since chests were useful as seating and provided access via the front rather than the top, they were more convenient, and raising the chest higher made frontal access easier than having to bend down. Consequently, the cabinet, as a form of front-opening chest placed on top of another chest or on a table, and ultimately on its own legs, was born.
