Description

The present invention relates to knockdown furniture.

Conventionally, this type of furniture includes, for example, a support structure that can be transported independently, a top plate that is attached and supported on the support structure, and a curtain plate that is detachably attached to the side surface of the support structure. etc. are known (see, for example, Patent Document 1).

In such furniture, the support structure, the top plate, the curtain plate, and the like are packed and stored in an independent state, and are assembled by transporting them to the site.
