1. An extendable and retractable sofa armrest assembly, comprising:
a fixed inner panel configured for attachment to a side of a sofa body;
a movable outer panel parallel to and spaced apart from the fixed inner panel in a left and right arrangement;
an extendable and retractable assembly provided between the fixed inner panel and the movable outer panel, the extendable and retractable assembly comprising two rotational rods that are hinged together crosswise and capable of rotating relative to each other, thereby enabling the movable outer panel to transition between a folded position towards the fixed inner panel and an open position moving away from the fixed inner panel;
an armrest cover enveloping both the inner panel and the outer panel, the armrest cover forming a flexible support portion for the armrest between the inner panel and outer panel;
wherein in an in-use state, the movable outer panel is in an open position, and the armrest's flexible support portion is correspondingly tensioned; in a packed state, the movable outer panel is brought closer to the fixed inner panel to compress the thickness of the armrest assembly, and the armrest's flexible support portion is correspondingly relaxed.
