Uppababy Aria V2 - owner feedback

The Best Parts

Extremely light at just under 6 lbs — one of the lightest infant seats available
Clips directly into UPPAbaby strollers (Cruz, Vista) without an adapter
No-rethread harness makes adjustments easy as baby grows
Comes with a load leg on the base, an infant insert, and an all-weather foot cover

Potential Dealbreakers

Chin-to-chest positioning complaints have followed the UPPAbaby car seat line, and some parents report the Aria V2 still has this issue
Babies run noticeably hot in the seat — one owner described a sweaty back even in a 69°F car after short trips, and UPPAbaby had no real fix
Lower weight limit (22 lbs) means a shorter usable lifespan than competitors like the Nuna Pipa (35 lbs)
Replacement inserts are hard to find — a real problem when blowouts happen and the seat needs to air-dry
