A multifunctional sofa includes armrest assemblies and seat units. A middle armrest is arranged between the adjacent seat units, and a front end of the middle armrest is provided with a cupholder. An upper end surface of the cupholder is provided with a cup slot, and an outer cover is also provided outside the cupholder. The outer cover may rotate relative to the cupholder to allow the one cup slot to be unfolded or folded. A movable function rack capable of rotating outwards relative to the armrest assembly is arranged in each of armrest assemblies. The movable function rack is provided with a function table. In the hidden position, the movable function rack is entirely located in the accommodating groove. In the use position, the movable function rack rotates outwards from the accommodating groove to protrude from the armrest assembly, and the function table is exposed outside.

A ready to assemble or knockdown sofa having a back rest that can be reconfigured between a use configuration in which the sofa is has a conventional L-shaped cross-section and a shipping or storage configuration in which the sofa is arranged in a more efficiently stacked rectangular cross-section. The rectangular cross-section allows the sofa to be more efficiently stacked with other sofas during shipping or storage. The back rest has an upper back rest portion and a lower back rest portion in which the upper back rest portion can be rotated forward toward the front of the sofa and downwardly into a nesting region against the top of the seat base to provide a more efficient shape.
