Meet the UPPAbaby Aria V2: Small Upgrades, Big Difference

UPPAbaby’s lightest infant car seat just got an upgrade! The new Aria V2 builds on everything parents loved about the original Aria: easy portability, sleek design, and seamless stroller compatibility — and adds smart improvements for even more comfort and convenience.

The first Aria made waves when it launched in 2024 for being just 6 pounds, one of the lightest infant car seats ever. Now, the Aria V2 keeps that same easy-to-carry feel but gives families a little extra room, better airflow, and a stronger, more intuitive base system.

Aria V2 vs. Aria: What’s Changed

Parents loved the simplicity and travel-friendly size of the original Aria, but some found that babies grew out of it a little sooner than expected. The Aria V2 fixes that with a slightly longer seat, giving your little one more space to grow, without adding any extra weight.

Other updates include improved ventilation panels to help keep baby cool and comfortable, and a redesigned base that feels sturdier and locks in with even more confidence. UPPAbaby also removed the red indicator from the base, which some parents found confusing — making installation that much simpler.

What’s New on the Aria V2

Longer seat design for extra growing room
Better ventilation for more airflow
Included All-Weather FootCover ensures baby is secure and cozy, perfect for colder weather
Upgraded base with stronger, smoother locking system
Simplified design (no more confusing red indicator!)

Lightweight Feel, Heavy-Duty Features

Even at just 6 pounds, the Aria V2 doesn’t skimp on safety or comfort. It features a load leg and Anti-Rebound panel for extra stability, advanced side impact protection, and a no-rethread harness that adjusts as your baby grows.

The seat also includes a two-piece infant insert for newborns and preemies starting around 4 lbs., plus an extra-large UPF 50+ canopy with a pop-out sunshade and ventilation to keep baby cool and protected. The included All-Weather FootCover means your baby stays comfy year-round.

For convenience, the SmartSecure System makes installation nearly foolproof with a red-to-green indicator that shows when it’s properly installed. It’s also European belt routing–compatible, perfect for travel or rideshares when you’re not using the base.

Why Parents Love the Aria System

The Aria V2 connects directly to the UPPAbaby Vista and Cruz strollers without adapters, and can also work with the Minu, Minu Duo, and Ridge, and even select Thule, Veer, and BOB strollers when paired with the right adapters.

If you’re a city family who often uses rideshares or public transportation, the Aria V2’s lightweight design and baseless install option make it a dream to travel with. For suburban families juggling multiple cars, an extra Aria base can make daily life much easier — just click in and go, no reinstalling required.

A Great Match If:

You’re pairing it with the UPPAbaby Vista or Cruz stroller — the Aria V2 clicks in directly, no adapters needed.
You want an infant car seat that’s lightweight and easy to install, complete with a stabilizing load leg for added safety.

Why Choose an Infant Car Seat?

Parents sometimes wonder whether to start with an infant car seat or a convertible model. While both are safe, an infant seat offers more flexibility during those early months. You can buckle your baby in at home, carry them to the car without unstrapping, and easily click the seat into your stroller — making errands and naps on the go so much easier.

It’s also a major convenience for travel: lightweight, portable, and far easier to manage than a bulky convertible seat.

Compatible Strollers

The UPPAbaby Aria V2 integrates perfectly with the UPPAbaby ecosystem and works with:

Vista and Cruz (no adapters needed)
Minu, Minu Duo, and Ridge (with adapters)

It’s also compatible with select other brands:

Thule Urban Glide 3 (Single, Double, and 4-Wheel) — with universal adapter
BOB Single Strollers (2016–Present) — with adapter
Veer Cruiser, Cruiser XL, and Switch&Roll — with adapter
Mima Xari, Xari Sport, and Zigi — with adapter
Valco Trend Duo — with adapter

Do You Need an Extra Base?

If you use multiple cars or have grandparents or caregivers driving your baby, an extra Aria base is worth it. Once installed, the base stays secure in each vehicle — just click the car seat in and out as needed.

Families in cities who rely on rideshares may not need an extra base since the Aria V2 can be installed safely without one using the European belt routing method.
