Review: I love the UPPAbaby Aria car seat! It feels really sturdy and safe, which gives me peace of mind when driving. The padding is soft and comfy for my baby, and the harness is easy to adjust as she grows. Installation was simple, and it fits nicely in our car without taking up too much space. I also love that it’s lightweight enough to carry in and out easily. Overall, it’s a great car seat — safe, comfortable, and easy to use. Definitely recommend to any parent! 🚗💖
Review: LOVE this carseat. It’s the lightest one we could find and makes transferring from car to stroller super easy. Fit my 6lb newborn well and still working great at 13lbs, I expect most babies outgrow this car seat based on height instead of weight but we still have a good amount of time with it I think! Seems comfortable and secure, but the harness is still pretty easy to adjust. The initial installation of the base was a pain, and we did have to level it with a towel underneath, but once we did that it has been extremely stable in our car. We haven’t used it without the base yet but like that you have the option to do so (and we will when we travel over the holidays). Definitely recommend installing and practicing with this car seat a few times before delivery day, but once you’ve used it a few times, it’s super straightforward!

## Features

- AS LIGHT AS IT GETS: With its featherweight design at just under 6 lbs., the Aria was designed to define new standards for on-the-go parents. Its strong yet light build with SmartSecure system and XL canopy provides a safe and comfortable ride for baby.
- LIGHTWEIGHT PORTABILITY: The ergonomic aluminum carry handle is designed for lightweight portability. The Aria has a 17” footprint to maximize space and accommodates European routing when installed without a base. It’s FAA certified for aircraft use.
- XL CANOPY WITH EXTENSION: The extra-large UPF 25 plus hideaway canopy with back panel ventilation and pop out extended sunshade intuitively provides additional airflow and sun protection when needed and can be simply pushed back when not.
- ENHANCED SAFETY plus INSTALLATION: Included base has a load leg and Anti-Rebound plus Panel that provides stability. The base helps limit rotation during a collision and reduces the chance of injury. Easy install with our SmartSecure system, auto-retracting LATCH.
- NO RE-THREAD HARNESS: The adjustable headrest offers a no re-thread, 5-point harness for a more accurate and customized fit as baby grows. Plus, our simple one-crotch buckle position makes buckling up a breeze.
- OPTIMIZED FIT SUITABLE FOR PREEMIES: The robust two-piece infant insert ensures proper fit and body positioning for preemies from approximately 4 lbs. with ability to fit babies up to 4 months.
- FIRE RETARDANT FREE FABRICS plus FOAMS: The Aria is made with both fabric and foam that is free from all fire-retardant chemicals for all fashions, including the large UPF 25 plus hideaway canopy.
- PROTECTION FROM ALL SIDES: The adjustable headrest is reinforced with EPP foam to help absorb energy while the integrated design of our Side Impact Protection keeps baby’s head protected during a collision. Additionally, the 5th rebound carry handle position allows for increased safety and aids in absorbing rebound forces.
- INSTALL IN SECONDS: We make installation quick and simple by combining our SmartSecure system, auto-retracting LATCH design, bubble level indicators, and red to green visual indicators. The base is also designed with a four-position adjustable foot for easy leveling during installation.
- TRAVEL SYSTEM: For the ultimate in portability and safety, Aria directly attaches to both the Vista and Cruz strollers. It is even compatible with the Minu, Minu Duo, and Ridge with the addition of convenient adapters. This creates a stylish and simple solution that goes from drive to stroll.

*by M***. on 11 October 2025*

I love this car seat! It’s super light and easy to use and install in the car. The size was perfect for our baby since she was born about the size of a preemie so the infant insert helped keep her secure. The material was also really nice and you could tell it was good quality. I love how much sun shade protection there is too. It easily clicks in and out of the base and also into the stroller (we got the Uppa Baby Vista). Overall, I think this is a great product and worth the price.
