Description

{MULTI FUNCTIONAL DESK COMBINED TABLE}

The present invention relates to a desk, and more specifically, to a multifunctional desk that doubles as a table.

Tables have been used since ancient society and have developed into various shapes. As time goes by, materials such as wood, bronze, and marble have become more diverse, and the appearance has gradually become more luxurious, with carvings, inlays, and plating on tables and legs, until the 19th century. It changed from a focus on decoration to a more functional form. There are various types of tables depending on their purpose. Among them, the tea table refers to the smallest of the reception tables. As the standard of living improved and tea culture developed, each household began to prepare and use a separate tea table, and it also came in various shapes. And because it was clean, its use increased.

In addition, tea tables are mainly used to place drinks, tea, newspapers, magazines, etc., making it difficult to use them for reading or similar study purposes, while desks are used for purposes other than reading or studying. It was difficult to sit down and use it as a tea table, etc. In other words, tea tables and desks have different functions, so it is difficult and inconvenient to sit and use them as a tea table or desk.
