Nuna TRIV next vs Chicco Corso Primo
At the same $600, the first thing you notice is weight: the TRIV next is 18.4 lb and the Corso Primo 26 lb, a gap of 7.6 lb. The Corso Primo repays it in the newborn months. With its infant insert the seat goes nearly flat and faces you, so Chicco says newborns ride in carriage mode, whereas Nuna recommends a Pipa until about 6 months and owners report the US seat does not lie flat. The Corso also has the taller handlebar, 39.5 to 44.5 inches, and owners say its rubber tires and rear suspension cope with dirt paths and gravel. Both include a car seat adapter, Nuna's for the Pipa and Chicco's for KeyFit only, so a non-Chicco, non-Nuna seat rules out both. Folded, the TRIV is 24 x 22.5 x 15 inches and the Corso 15.5 x 24.8 x 32. A KeyFit owner barely has to think about it. With a Pipa, the question is whether 7.6 lb less on the stairs is worth a seat that does not lie flat.
Folded, the Nuna TRIV next makes a 4.69 cu ft box to the Chicco Corso Primo's 7.12 cu ft. Neither fits a 22 x 14 x 9 in carry-on sizer: the Nuna TRIV next misses by 8.5 in and the Chicco Corso Primo by 10.8 in. The Nuna TRIV next is 7.6 lb lighter by its maker's figure (18.4 lb to 26 lb). The Chicco Corso Primo is newborn-ready as sold; the Nuna TRIV next needs a bassinet, insert or infant car seat for the first months.
