Abstract: A substructure in an aircraft cabin includes a drawer-insert accepting portion that defines multiple racks. Each rack may receive an exchangeable drawer insert. A module-accepting portion of the substructure defines an opening that includes a supporting surface, a back wall which extends upward and outward, and a lateral side wall. A module is provided for optionally installing in the module-accepting portion. The module has concealed areas upon installing that include: (i) a base adapted to rest on the supporting surface, (ii) a side wall adapted to abut the lateral side wall, and (iii) a rear wall adapted to abut the back wall. The module has exposed surfaces upon installing that are adapted to match an existing profile of the drawer-insert accepting portion. The module-accepting portion is configured for stowing cargo in a first mode and for receiving the module in a second mode. The module may include a locking assembly.
