When it comes to designing rear-facing seats, CYBEX puts safety a top priority. The company conducts hundreds of crash tests every year to ensure that the child restraint system is unparalleled. That’s why the Cybex Aton 2 sports impressive safety features that are unique to this model. 

Apart from its plush and comfortable material, some of its distinguishing features include the following

Ultra lightweight

Weighing in a total of 9 lbs, the Cybex Aton 2 is one of the lightest infant car seats on the market today. Because of this, it’s easy to carry around and set up in different vehicles without compromising the comfort and safety of your baby.

Likewise, if you’re the type of family that likes to travel a lot, the lightweight feature makes it hassle-free to lug around during your trips. 

SensorSafe Technology

While you’re driving, it can be difficult to keep tabs on your baby. So, the company installed a SensorSafe Technology that sends you real-time alerts regarding the safety of your child. By downloading the app and connecting it to the receiver of your vehicle, you can instantly enjoy this innovative feature. 

Load Leg Base

Speaking of safety, Cybex Aton 2 also has a load leg base integrated into the infant seat, which effectively transfers up to 50% of the impact of the crash from the car seat to the vehicle floor. This added element helps distribute the energy force away from your baby to ensure that he remains unharmed in the event of an accident. 

Linear Side-Impact Protection (L.S.P. System)

While the Load Leg Base absorbs the impact from the base, the Linear Side-Impact Protection absorbs the initial brunt force from both sides of the car seat, thereby, reducing the amount of damage to up to 25%. With both features combined, your baby can experience a well-rounded protection that many other infant seats do not offer.

Among the many infant car seats in the market, the Chicco Keyfit 30 ranks as the number one model for its easy, accurate, and secure installation and innovative features. These are:

Foolproof Set-up System

One of the biggest selling points of the Chicco Keyfit 30 is its straightforward installation system that includes the following elements:

  • ReclineSure Leveling Foot
  • RideRight Bubble Level Indicators
  • SuperCinch LATCH Tightener

These innovative technologies enable you to place your infant car seats at the right angle, establish the proper balance, and tighten the harness to ensure your child’s safety and comfort. Thanks to the manual’s visual markers and rigorous step-by-step procedure, you can easily follow the set-up instructions and finish the entire princess in as fast as five minutes.

Removable and Washable Fabric

Besides that, this rear-facing car seat also has a removable and washable carrier fabric that’s a major plus for many mothers. Since juice spills, diaper blowouts, and food stains are almost always a surety in the baby world, having this feature makes it so much easier for parents to constantly maintain the cleanliness of the car seat and, therefore, extend the lifespan of this product. 

Tried and Tested Security System

Similar to the Cybex Aton 2, the Chicco Keyfit 30 makes safety a priority. Manufactured in compliance with Federal Safety Standards, the product’s body and head support promotes a secure fit for newborns and smaller babies. The car seat’s shell is lined with an expanded polystyrene foam (EPS) to improve impact protection in the event of accidents. 

The product also features a 5-point harness system with a single-pull strap, making it easier for parents and caregivers to use. With just a push of a button, you can easily buckle in or release your child from the car seat without giving them much time to make a fuss.

Through these features, Chicco has become a trusted brand for many families who enjoy going on road trips. Apart from the Chicco KeyFit 30, you can also check out the Chicco travel systems reviews and the Chicco NextFit reviews to explore other products the company offers.

Having this information may be a lot to digest in one sitting, so let me try to simplify it for you by showcasing their key differences. 

Weight Restrictions

Although both the Chicco KeyFit 30 and the Cybex Aton 2 work for newborn babies weighing as little as 4 lbs., they differ in the maximum weight capacity. 

  • For the Chicco KeyFit 30, their maximum weight capacity is 30 lbs.
  • For the Cybex Aton 2, their maximum weight capacity is 35 lbs. 

Because of this, the Cybex Aton 2 is more suitable for bigger babies. 

Safety Features

In terms of safety, both infant car seats provide innovative features that ensure your baby remains secure in their vehicle seat. But to give you deeper insights, here is a list of pointers that I like about each of these models that give it its high safety ratings among several consumer reports. 

  1. The Chicco KeyFit 30 is designed with a thick, well-cushioned seat that not only promotes safety but comfort as well. 
  2. The cushions in the Chicco KeyFit 30 are made with an energy-absorbing foam that can significantly increase your child’s protection during a car crash.
  3. The Cybex Aton 2 has a base and side-impact protection features that likewise absorb impact, but they’re not integrated into the model’s foam. Instead, the model uses a lightweight metal base and frame to make this work. 

With these additional safety features, both models will work just as effectively to keep your baby protected against potential harm on the road. 

Additional Features

More than the essential components, you should also take a look at other fun features each of these infant car seats offer. 

For the Chicco KeyFit 30, expect to see:

  1. All-weather boot
  2. High compatibility with other strollers like Chicco Bravo, Urban, Neuvo, and Activ3
  3. Removable insert perfect for smaller babies
  4. Seven color options

Moving onto the Cybex Aton 2, here’s what you can benefit from:

  1. Compatibility with the Cybex travel system
  2. Foldaway canopy
  3. Removable insert perfect for smaller babies
  4. Four color options

Price Range

As awesome as these products sound, you might be wondering: how much do these convertible car seats cost? Both of these are above average price, but they’re also worth the investment especially with the features they offer. The Chicco Keyfit 30 costs around $200 while the Cybex Aton 2 costs anywhere between $300 to $400. When you buy either of the two, the package will include the base and the car seat body for your ultimate convenience and ease of installation.
