Like most compact hatchbacks, the Giulietta isn’t the last word in versatility. As with most rivals, you can fold the rear seat backs forwards for extra load space and that’s about it.
Tipping the seat backs (which have a 60/40 split) forward is easy, requiring a tug on a handle at the top of it. The cushion stays in place, leaving a reasonably long area with raised, sloping section.
All but the entry-level car have passenger seat height adjustment; a central rear armrest with storage compartment, third rear head restraint and through-load system is standard for the top three trims, optional for the one beneath that, and not available for the two cheapest versions.
