Nuna SWIV vs Nuna TRIV lx
Folded, the Nuna TRIV lx makes a 5.27 cu ft box to the Nuna SWIV's 5.37 cu ft. Neither fits a 22 x 14 x 9 in carry-on sizer: the Nuna SWIV misses by 8.5 in and the Nuna TRIV lx by 9 in. The Nuna TRIV lx is 0.7 lb lighter by its maker's figure (21.1 lb to 21.8 lb). The Nuna TRIV lx is newborn-ready as sold; the Nuna SWIV needs a bassinet, insert or infant car seat for the first months. Nuna PIPA series seats click straight onto the Nuna TRIV lx; every seat listed for the Nuna SWIV needs an adapter.
