    Safe, Comfortable, and Easy to Use – UPPAbaby Aria Car Seat
    I recently purchased the UPPAbaby Aria car seat, and I couldn’t be more pleased with the decision. From the moment we installed it, I was impressed with how simple and straightforward the setup process was. The base is easy to install, and the seat itself clicks securely into place with minimal effort.The car seat is incredibly comfortable for my baby. The fabric is soft and breathable, and the cushioning provides excellent support for those long car rides. I also love the adjustable harness system, which grows with my baby and ensures a snug, secure fit every time.Safety is always a top priority for me, and the UPPAbaby Aria car seat does not disappoint. It has a solid, sturdy design and meets all the safety standards, giving me peace of mind knowing my baby is well-protected. The side-impact protection adds an extra layer of security, which is reassuring.One of the best features is its compatibility with the UPPAbaby Vista stroller (and other UPPAbaby models), making it incredibly easy to create a travel system for our outings. The car seat clicks easily into the stroller frame, and it’s lightweight enough for me to carry it around without straining.Overall, I highly recommend the UPPAbaby Aria car seat. It combines safety, comfort, and convenience, making it a must-have for any parent looking for a reliable and high-quality car seat.

    Buy it!
    Our first baby was so uncomfortable in a Graco infant seat and cried every drive. So we decided to go with this higher quality car seat for our second baby and it does not disappoint! The base is very user friendly and easy to instal. The car seat feels very comfortable for baby. It’s easy to click in and out of the base. It’s lightweight and has lots of ventilation. I like that the sun shade extends if needed- that’s something that would’ve been very useful for our first baby. I appreciate that the handle bar is NOT plastic and can be positioned forward while in the car for added safety. This car seat is on the smaller side, but all the padding can be removed and the head piece easily adjusts up and down to grow with baby. Really cool feature! We’re extremely happy with this car seat and I would highly recommend it!

    Lightweight, safe and comfortable
    Light!! Very nice fabric. The straps to get it tight is a little fussy. Might just because our guy is still little. May get easier when he’s bigger. Comes with infant newborn booster don’t forget to remove when they are bigger than 10lbs! Good directions would buy again

    Best car seat!
    Love this car seat! Easy to install and SO lightweight which is so nice since I had an almost 9lb baby! And it’s compact enough for our sedan & small suv!

    Beautiful!
    I have been eyeing this since I found out I was pregnant. Once I found out we were having another boy this was the color I decided on. I have always been a Graco mom but decided to splurge a little, since it is our last baby.This car seat does not disappoint. I still have a few weeks to go until his arrival but wanted to be prepared.My first thought was the box is heavy. After taking it out though I realized it is a very light weight car seat. I like that the canopy comes down so far and the color is beautiful.This seems like a very sturdy, well made car seat and will keep your little one safe.I look foward to using it.The only disappointment I had was that my box did arrive ripped open, which I was worried about damage but thankfully it was okay!

    Love!
    We love the Uppababy car seat. It’s so lightweight so it’s not uncomfortable carrying and snaps right into the stroller without an adapter

    Love this car seat!
    3/8/25 update!I have no regrets buying this car seat. My baby is growing fast and getting heavy (16lbs) now and carrying her in and out of my small hatchback has been easy!!The only downside to this seat is that my baby gets hot easily. If she is in it more than 45 min, her back is a bit sweaty.Original:I ordered a Graco snugride snugfit 35 and had another Graco before that were very budget friendly, but was loud and the canopy would pop off. I also compared the Aria with the Nuna brand car seats the fabric on this Aria was so much softer. It is ultra lightweight, and the base was so straightforward to install. There are way too many options for car seats out there but I’m so happy with this one that I’ve stopped looking! Plus, the warranty is amazing!

    Lightweight and perfect size for our newborn
    We were able to try both Mesa v2 and Aria on our newborn from when he was 7 lbs (Mesa v2 only) to 8.5 lbs (Mesa v2 and Aria), and 20 inches.Pros (vs Mesa v2):1. You can definitely tell the weight difference with and without the baby on. Aria was easier to carry around.2. Perfect fit for our baby. Aria eliminated chin to chest (with infant insert) which occured on the Mesa v2. This alone would make us rate Aria with 5 stars.3. Extended canopy offers better privacy and shade.4. Seat base offers more safety features with additional load leg.Cons:1. The release button is placed much lower for both stroller and car base, and is harder to reach. But I guess this is the trade off for a lighter car seat. Otherwise, we had no problems attaching and detaching the car seat to the stroller or the base.2. Handle bar levers are not as “single press” compared to the Mesa. We often had to press multiple times to change the handle bar positions. This gets irritating if you are in a hurry and would want to adjust the handle bar from anti-rebound to carrying position.Overall, we are happier with the Aria, especially due to our baby not having a chin to chest when on it.
