Doona X vs Peg Perego Vivace
One of these is a car seat. The Doona X is a rear-facing infant seat on wheels, rated to 30 lb and 32 inches, so it is outgrown within months; it costs $850 and weighs 19.6 lb. The Peg Perego Vivace is an $800 stroller with a reversible seat from birth to 50 lb, though Peg Perego publishes no folded size. The Doona buys a few months of moving a sleeping baby from car to pavement without unbuckling. The Vivace is bought once.
Only Doona publishes a folded size for its model here; Peg Perego gives none for the Peg Perego Vivace, so only one side gets a carry-on verdict. The Doona X is 1.12 lb lighter by its maker's figure (19.6 lb to 20.72 lb). The Peg Perego Vivace is newborn-ready as sold; the Doona X needs a bassinet, insert or infant car seat for the first months.
