The innovative technology behind the Cybex Aton M and SafeLock? Base combination offers easy functionality in a safe and thoughtfully designed infant car seat. The Aton M Linear Side-Impact Protection System helps absorb impact forces, while the adjustable headrest allows the seat to grow with your child so their delicate head is fully protected. The included SafeLock? Base features an anti-rebound design and a load leg for additional safety while your child rides comfortably in their car seat.
  • CYBEX’s Linear Side-impact Protection System (L.S.P.) absorbs up to 25% more impact forces in the event of a side impact*
  • 11-position height-adjustable headrest with an integrated no-rethread harness that grows with your child
  • Energy-absorbing shell helps absorb the forces of an impact and protects the baby
  • Integrated extended XXL foldaway sun canopy with a UPF 50+ rating to protect baby from the sun’s rays
  • European belt routing provides safe installation in a car or taxi without a car seat base
  • Removable newborn inlay provides additional support for premature and very small babies

SafeLock Base

The SafeLock? Base works seamlessly with the Aton M car seat, offering a new anti-rebound design and a height adjustable load leg, to provide extra stability and safety. An extra car seat base can be handy for families with multiple cars and/or caregivers to help transition baby to and from the vehicle without the need to reinstall depending on who they are traveling with.


  • Anti-rebound design provides additional protection in the event of a crash by limiting the car seat's movement towards the back of the vehicle
  • Highly visible indicators change from red to green when the car seat is locked into the base and the load leg is properly installed for extra safety
  • Height-adjustable load leg helps reduce crash energy by redirecting forces to the vehicle floor and away from your baby
  • One-hand release buttons allow for easy removal of the car seat from the base
  • Dual Level Indicator ensures the infant car seat is reclined at the proper angle
  • Unique belt tensioning system offers quick, simple and secure installation when using either LATCH or vehicle seat belts
  • Measurements: L 26.3 x W 15.4 x H 13.9 inches
  • Weight: 12.4 lbs.

Useful paired with pockit stroller
June 23, 2023
Love that I can use it with my stroller (pockit). Base is my absolute nightmare. It is impossible to snap in. I just buckle it in now.

Gets stuck in the base!!!!
October 10, 2021
I spend 3-5 minutes every time getting the base in or out of the car. Huge safety hazard. Poor kid gets slammed around and jiggled in order to get securely in. This is my 4th daughter and i chose to buy a new infant seat. Regret giving up my britax.

Great car seat for a low price
September 21, 2021
It is a realy great car seat. We used it for air traveling as well. And the load leg and european seat belt bath give it a huge safety benefit.
But check the fit for newborns, ours was to smal and needed a few weeks to fit.
  • Safety
  • European seat belt bath
  • Load leg
  • Good fit
  • Not for newborns
  • Can outgrow fast if the baby has a big head

Just perfect

I did extensive research before landing on this beautiful car seat for my 4th child. I’ve had Graco’s and a Britax but knew cybex technology was it for me this round. Albee Baby is my new favorite site for baby necessities! Shipping was extremely quick, price was great and the car seat is amazing. Highly recommend the product and Albee Baby - you won’t be disappointed
  • Sleek, beautiful materials, gorgeous color, safety features, lightweight, compatibility with stroller options.

Great car seat

Highly recommend. Love the color. Very safe. Fits even my premie that weighed in at a whopping 4 lbs 2 oz. Very safe. Wish this color wasn’t more expensive than the others tho. Seems silly.

This is so much nicer than our last one, and at the sale price, not much more expensive either. I find the new safety features really reassuring.

The Cybex Aton M came promptly, exactly as advertised. Easy to read instructions and seems relatively simple to manage. The price through Albee Baby was excellent- I would definitely buy it again if I needed to!

Cool cover and handsome car seat

Really like it- we work overseas and are planes a lot- works well with our super cool Babyzen YOYO stroller we also bought here. Great value compared to what we see in the Middle East or Europe

Infant Insert Super Handy
June 3, 2019
Sturdy, well made product. Infant insert really managed to make baby comfortable yet safely positioned within the car seat.
  • -Infant insert moves naturally as straps are adjusted for a growing baby.
  • -Super comfy padding, baby fits as if in a cloud.
  • -Very easy to adjust and readjust as needed.
  • -Sun canopy really extends out, it brings great coverage against the elements.
  • -Looks super nice on its own and as part of a travel system!
  • -Not the lightest car seat, quite the arm workout as baby starts growing.
  • -Material is quite warm, do not leave car seat in car in warm temperatures.
  • -Says one hand latch release from base but there?s a latch on either side of the car seat. So it?s quite the coordinated effort.
  • -Base install took a bit of research since the level would not rest within the green range.

We love this carseat, it's stylish and most importantly safe. When we got it, we had it installed by a carseat expert and she was super impressed by all the safety features. 100% recommended!
