By definition, a table is a piece of furniture that has a flat surface (usually round or square) with attached legs that hold it upright.
A table is used to hold a variety of objects ranging from food to boxes, merchandise, or an endless variety of things for various purposes.
We are all familiar with the modern table and how they are used, but the question is can you define a table based on the types of chairs that is uses, if it even uses chairs at all.
Many early table designs incorporated drawers.
This was common as the table could be used for additional storage area and would not typically utilize chairs.
Today, a table that uses drawers is commonly referred to as a desk, which may have one or more drawers in its base.
But a desk, and a modern dining table for that matter, use a standard chair or stool as its matter of seating.
A picnic table and some other outdoor tables use benches in lieu of chairs or stools to seat people.
Although common for the outdoors, an indoor table rarely uses a stool for place settings.
Can this still be classified as a table? By definition yes, although in today's modern interior having bench seats anywhere in the home would be considered a major decor gamble.
The reason for this is that bench seats take up quite a bit of space and cannot be easily moved from their static location.
If you think about it, how many times have you seen someone take a bench seat from a dining room to the kitchen to add additional space? It's not very likely, although if a room has sufficient room and a seating arrangement that would not change often, there very well could be a use for a dining room table with a bench seat.
This is not to say that a bench seat is not useful, but having one in a dining room can severely limit the mobility and space of a room.
