Whether you have a small dining room and you are in need of a larger table when you are using it for dining purposes, or you have a small family with no need for extra seating unless family is visiting, an expandable dining room table will be an excellent addition.
The size of the table that you choose will of course depend on the size of the room. You need to make sure that you have a few feet behind each chair for walking space. In addition to walking space, make sure that you have plenty of room for a nice china cabinet or buffet table to place in the room if need be.
