Uppababy Aria V2

68 / 100 SRI

The Aria V2 wins fans for its featherlight 6-lb weight and seamless fit with UPPAbaby strollers — no adapter needed. But recurring worries about chin-to-chest positioning and heat retention give many parents pause before committing.

Higher SRI

Nuna Liing Infant Car Seat

86 / 100 SRI

Early feedback from the available sources is extremely thin on the Nuna Liing specifically — most comments mention it only in passing as a premium, well-regarded option. What little signal exists points to strong build quality and a loyal following, but there isn't enough direct owner experience here to give a full picture.

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

Nuna Liing Infant Car Seat - owner feedback

The Best Parts

Consistently mentioned alongside top-tier infant seats, suggesting strong reputation among informed buyers
Praised for build quality and materials — one owner who loved their Clek Liing used it as the benchmark when shopping for a convertible seat
No-flame-retardant materials noted as a selling point by parents who care about that
Compatible with popular strollers like UPPAbaby via adapters, which matters to parents building a travel system

Potential Dealbreakers

Price is a consistent sticking point — regularly described as 'way too expensive' or nearly double the cost of competitors like Graco
At roughly $500–$700, it's out of budget for many families who feel cheaper seats cover the same safety basics
Very limited first-hand owner accounts make it hard to assess real-world comfort, fit, or longevity
Stroller compatibility can require extra adapters depending on your setup, adding complexity
