What are the Feng Shui taboos when using a round bed?

Sleeping in a round bed is not good for marriage and relationships.

The aura of a round bed is introverted. Sleeping on a round bed makes it impossible to completely relax your mind and get real rest. If this happens for a long time, your own physical strength will feel overwhelmed; and it is easy to avoid and reject the people you share the bed with.

The round bed has no fixed head and feet. The uncertainty at the head of the bed makes the relationship more volatile; the uncertainty at the end of the bed makes it difficult for the relationship to last long. (If there is a headboard, this situation will be somewhat improved, but it cannot be completely eliminated)

The circle itself has no distinction between guest and host, so the round bed has "one quilt for everyone to cover" the taste. Couples or lovers who sleep on round beds often develop polyamorous relationships.

If you don’t want to have an affair and don’t want a third party to sleep in your bed, it’s better not to use a round bed.
