CYBEX Aton 2 Infant Car Seat offers your baby a plush, comfortable environment while making it easier for you to use every day. The Aton 2 takes safety and comfort seriously with Linear Side-impact Protection (L.S.P.), which reduces collision forces by up to 25% in a side-impact crash* and a load leg base which stabilizes the car seat and can reduce seat rotation by up to 50% in a front impact crash*. SensorSafe™ car seat safety technology allows you to gain instant insight into your child's well-being - right to the SensorSafe app on your phone.

*as compared to the same seat without this feature

With SensorSafe™, you'll gain instant insight into your child's well-being—even when your eyes are on the road. Built into the chest clip of CYBEX car seats, the SensorSafe clip connects to a vehicle receiver which sends alerts about your child's safety, right to the mobile app on your phone. It's the kind of unparalleled safety technology you've come to expect from CYBEX.

Linear Side Impact Protection is a feature of CYBEX car seats that absorbs impact forces of certain side-impact crashes and directs these forces into the energy-absorbing shell of the car seat and away from the child’s sensitive neck area. By extending the L.S.P. system on the side of your car seat facing the door, this feature takes the initial brunt of the force and helps keep your child safer in the event of a near side impact. Car seats with L.S.P. extended see a reduction in near side-impact forces on the baby by up to 25% when compared to the same car seat without L.S.P. extended.

A load leg is a structural element that is integrated into the base of a car seat. It extends down to the vehicle floor and helps to distribute the crash forces away from the child by transferring the crash energy to the vehicle’s floor. The load leg is height adjustable so it can be perfectly suited to your vehicle. The load leg stabilizes the car seat and can reduce crash forces by up to 50%.

At 9 lbs., the Aton 2 is very lightweight, making carrying and installation easy. Thanks to its lightweight construction, the Aton 2 can be easily moved in and out of cars and carried around. All this while not making any compromises in safety and comfort.


  • SensorSafe is compatible with most vehicles 2008 or newer with an OBD II port. For detailed information on mobile phones and vehicles compatible with SensorSafe, visit

Meh Car seat. Stick with a chicco
April 18, 2023
This car seat is cheaply made. All you are paying for is the brand name. We bought this car seat for our second baby and we’re disappointed. Not much padding and cloth material used is worse than cheaper car seats. Plus, the plastic on the outside seems much more flimsy than our infant car seat we had for our fist born. The sensor is a good idea but is actually annoying as hell. You get notifications all day “Baby Left In Car” even when you have the seat right next to you. Our first born had a Chicco Keyfit and that was probably the best seat we have used in our house hold. Sturdy, comfortable, and so so easy to install in the car.
  • Looks nice.

GREAT car seat for newborns, light and easy to use

Safety first!
October 7, 2022
We are pleased with our car seat. This purchase took me the longest of all our baby purchases to make my mind up on. I compared safety rating on every reputable site, read 1000s of reviews & look at every feature. In the end, this seat best met the safety features I wanted for my son. It did not disappoint. The seat installed in minutes and feels very secure. I use the sensor safe more than I anticipated; especially for monitoring his temperate both in & out of the car. I would absolutely recommend this seat to a friend & would certainly purchase again. The only improvements I’d like to see ( and they are minor& not safety related)
A bigger sunshade
A more intuitive latch into the base
A better release from the travel system.
Thank you Cybex, for a wonderful product. 9/10!
  • Sturdy
  • Solid/ Safe
  • Sensor safe
Best Uses
  • Infant car seat
  • Travel system
  • Babies

I LOVED this car seat for my infant. It’s not as bulky as some others and the added safety features built into this seat are great for piece of mind being a first time mom.
  • Not so bulky, extra safety features
  • Grew out of it faster that other infant seat.

Nice Car Seats but Don’t Suggest for Premie/Early Term babies
June 27, 2022
My husband and I purchased 2 of these for our twins (boy/girl). Because they were born a little early and under a certain weight, they had to each do a car study with the car seats. My son passed his with flying colors. Unfortunately, my daughter didn’t pass hers and the hospital told us we had to get another car seat for her in order to take her home. Although he car seat was weighted for over 4lbs and our daughter was a little under 6lbs, it wasn’t enough for her to pass. After the 3rd test with a new car seat, she passed her test. After bringing her home and she got a little bigger, we used this car seat without any issues. We also used these car seats with the bumbleride double strollers. It was cumbersome to use the car seats with adapter.
  • Appears comfortable with for baby
  • My son passed his car seat study with flying colors at a little over 6lbs
  • Appears easy to clean (though surprisingly they didn?t make a mess in their seat)
  • It remained in place and secure in the car
  • Nice looking
Best Uses
  • It is best used if it stays in the car and you aren?t using it as a carrier.
  • I couldn?t use it for bringing my daughter home because she failed her car seat study in it (she weighted a little less than 6lbs)
  • Hard to snap in and out of the car seat base
  • Challenging to use with bumbleride stroller adapters (get car seat on and off adapters and navigating through certain doors)

Waited to review
September 8, 2021
I waited to review this seat until we used it for a few months. First things first, this is one of the safest infant car seats out there, according to Baby Gear Labs. I just didn’t realize it was considered the budget car seat for Cybex.

Now, I never got the sensorsafe work right but that’s the least of my worries. My experience has been meh. It’s safe and that was all that mattered til we realized this has one of the shortest height limits of all the car seats (30” instead of 32-35”). So due to my long boy, I have to already buy a new one.

The canopy on this, what were they thinking? What am I even blocking out with this? And if you bring this up to the company they get visibly annoyed that you bring it up.

The material doesn’t seem great but at the same time it’s cybex for the most part it’s built great. Just have normal sized babies I suppose and maybe don’t depend on the canopy (I use the Uppababy cabana to help out with that).
  • Super safe rating
  • Feels cheap
  • Poor canopy coverage and quality
  • Height limit of 30?

Comfortable and safe

My newborn is loving this car seat and I have a peace of mind with all of the provided safety features. The only (very minute) downside is that the bar attached to the car’s floor has to be adjusted often as it shifts pretty often.

Cool Car Seat
November 20, 2020
I received the car seat as a gift. It kind of makes a creaky noise when you move the handle up and down, but I’m hoping that’s just because it’s new. I had a difficult time getting the straps and head rest to adjust on it— I’m still trying to figure out how to get mine to cooperate. The sensorsafe technology is pretty amazing and will help me relax once I start using it for the baby. It’s not quite as light as review videos make it sound, but it’s not super heavy either. I love the look of it and it looks like it’ll be very comfortable for baby. The canopy is TINY, it may not even cover the baby’s head when I put him in it. I’m going to have to buy the canopy extender, but I’m guessing that was the ultimate strategy that the company used to make people buy more stuff from them. Overall, what I’m worried about is safety. This seat seems to be very safe and I feel very comfortable putting my newborn in it in the near future.
  • ? sensorsafe technology is comforting
  • ? extension on the sides protects from side impact collisions
  • ? the base and car seat together make me feel like my newborn will be safe
  • ? not extremely heavy
  • ? the handle is creaky and a little stiff when you move it
  • ? I still haven?t figured out how to adjust the straps and head rest on my seat, even though I?ve watched many how-to videos? the seat and straps just won?t budge
  • ? it?s not as light as the company makes it sound
  • ? canopy is absolutely tiny. If you get the seat you?ll have to buy a canopy extender from the company as well
