ABSTRACT:
A cushion, which is a solid structure formed by a cardboard, includes a first baseboard, a second baseboard, a third baseboard, a fourth baseboard, a fifth baseboard and at least one supporting board that are joined to each other. Those junctions are foldable. The fourth baseboard has a first baffle flap and a plurality of the first cut lines. The fifth baseboard has a second baffle flap and a plurality of the second cut lines. When the first baffle flap and the second baffle flap are side matched to form the solid structure, the portion of the fourth baseboard between the first cut lines and the portion of the fifth baseboard between the second cut lines are folded toward each other to form a concave. The supporting board is joined to a lateral side of the opening of the solid structure and folded to be a supporting structure to cover the opening.
