6 Best Cybex Car Seats of 2022 [For Infants & Toddlers]

Cybex car seats are designed with safety in mind. Some of the CYBEX seats are compatible with SensorSafe technology built into the harness clasp. This feature connects with your phone and send alerts so that you know if the temperature of the seat is elevated, the harness comes unhooked, or when the child has been seated for an extended period of time.

Cybex seats have additional linear side impact protection which absorbs energy from a collision and directs it away from the child. Multiple position headrests and no-rethread harnesses ensure that the seat can fit the child securely.

Cybex offers infant seats that have a full recline option for when the seat is outside of the car. The Cloud Q infant seat is excellent for premature infants due to its ergonomic positioning. The base of the infant seats features a load leg base.

This extends from the base of the car seat to the floorboard of the car to stabilize the seat in the event of a collision. These seats also have a seat belt guide for use when the base is not available as in a taxi.

The company also has convertible car seats rated from 4 to 120 pounds and up to 10 years. Cybex’s convertible car seats are equally safe, incorporating steel frames, side-impact protection, easy-to-change harness positions, and SensorSafe connectivity.

Our extensive research and testing have shown that Cybex’s best convertible car seat is the Gold Eternis S All-in-1. This seat accommodates infants as small as 4 pounds up to children weighing 120 pounds. The headrest can be modified for your child’s best fit.

This convertible seat uses the SensorSafe technology so that you can sync the car seat with your phone allowing you to keep an electronic eye on your child’s safety.

1. Cybex Aton M Infant Seat – Super Durable

The Aton M comes in seven different options with two different price points. It comes with Cybex’s patented linear side-impact protection as well as 11 different headrest positions to ensure the right fit for your new babe.

Energy Absorbing 

The seat’s shell is energy-absorbing, which is really helpful in case of a car accident. To add to the protection factor, the Aton M also comes with an XXL sun canopy with UPF 50+ protection. This infant seat will accommodate your little one from birth until they hit 35 pounds.

This is a double-win because its 4-pound minimum makes it perfect for preemie babies, and the 35-pound maximum helps reinforce the idea of extended rear-facing. The seat also lays flatter than any other infant seat, which is another major plus if you have a preemie. The seat insert is removable, and the seat itself is compatible with all Cybex travel systems as well as a few other select brands.

Buyers’ Guide

Cybex is a growing baby brand that operates under Goodbaby International. Since they were founded in 2004, Cybex has designed baby travel systems , strollers, and most popularly, car seats.

Additional Safety Features

All Cybex car seats come with a patented three-position headrest. The side-impact protection inside the headrest safely shifts the balance point of your child’s head to prevent their head from falling forward if they fall asleep. Not only will this allow for more comfort, but it keeps them safer as well.Most Cybex car seats will accommodate your little one while rear-facing up until around four years old.

The rear-facing position is the safest for any child, which is why so many brands are making more products for extended rear-facing mode. The unique thing about Cybex seats is that they come equipped with an impact shield. This shield is meant to give added protection if you need to switch your little one to forward-facing mode before they max out.

Along with these two safety features, Cybex seats are also equipped with linear side-impact protection and seat-to-chassis technology as well as Sensorsafe technology for some models.

Weight and Dimensions

A seat’s size and shape are huge deciding factors for parents. Most Cybex car seats are much lighter than seats of other brands, which is nice if you’re looking for a light infant seat or you don’t want to try installing a massive convertible seat. When choosing your car seat, make sure you keep in mind the size of your vehicle and the depth of your vehicle’s backseat.

Cleaning Convenience

If you’re an “on-the-go” family, ease of cleaning should be a major deciding factor of which seat you choose. When looking around, make sure to take note of special washing instructions and whether or not the seat’s cover can be run through the dryer.

Ease of Installation

Each Cybex car seat comes with LATCH compatibility. This makes them much simpler to install, which saves plenty of headaches later on.

An easy to install car seat is also important if you have to switch the seat between vehicles.


Last, but not least, your budget shouldn’t be ignored. If you’re looking to stay within a certain amount, Cybex car seats have varying prices. Even if you decide to go with a less expensive option, the safety features aren’t compromised to make up for a low price.

A Seat For Everyone

All in all, Cybex is a stellar brand when it comes to car seat safety and innovation. You could make the decision to buy a single car seat for each stage or you could buy a convertible car seat that grows with your child all the way up to 10 years old, or even older. The choice is ultimately yours whether you want to make the investment once or each time they outgrow their car seat. 

Additionally, the CYBEX car seat has unmatched safety features such as a 5-point safety harness and linear side-impact protection that absorbs up to 25% more impact. It also has a 12-position height-adjustable headrest to grow with your child. It’s not cheap, but the investment is only once as opposed to once every couple of years.
