Four-in-one foldable dining table

Abstract

A table with four chairs can be stored together into a secure, flattened assembly. The four chairs can store under the table such that, when the legs of the table are folded to be adjacent a back side of the table, the folded legs act as a stopper to prevent the chairs from sliding out when moving the table. The foldable chairs can include a foldable backrest and can have support bars between each pair of legs. The chairs can be folded in a flattened state to be disposed in a slot adjacent the underside of the top of the table.
