The most ideal table shapes for a feng shui dining room are a square
, round or oval. A rectangle is good as well if it is not too long. Dining room tables that are missing corners are considered unlucky except for the octagon which is considered to be an auspicious shape. It is also important that the dining room table is not too cramped in a space. This allows the chi and people to move freely and easily around the table. Feng Shui For Kids Room
