The dining room table is the most noticed and most used dining furniture. It is the focal point of the room. Other furniture found in the dining room like a wine cabinet must in a way flank the dining room table. They all must agree to the design and function of the dining table to create a more harmonious overall design and feel in the dining room.
Consider Shape. You have several shapes from which to choose. The two most common shapes are rectangular and circular. Some people prefer a circle shape believing that this shape facilitates better conversation. It's easier to fit more people around the table with a rectangular shape. If you add leaves to a circular table it will become an oval. An octagonal table is another option.
Consider Your Needs. Ask yourself what do you need in furniture for the dining area? The need determines the size and function of the furniture you'll get. A wine cabinet for example could be purchased by because one needs a large storage for wines in the house. The size of table you'll get is determined by the number of people who would use it. Big families would need a larger table to accommodate many people while smaller ones and maybe bachelors would need smaller ones. Function is also a consideration. Bachelors and smaller families may consider getting a dining table that have foldable extensions that may be put away if not in use just in case there might be surprise visitors.
