Has easier to use push-on LATCH connectors Tensioning plate can help provide a secure installation
- Consumer Reports
The base on the Anton 2 has a unique tensioning system for LATCH or vehicle belts.
- Baby Gear Lab
The Aton Q’s load leg is a “leg” that pops down (shown left) from the car seat base, which minimizes “rebound” and transfers crash energy to the floor of the vehicle and away from your baby.
- Lucie's List
Cybex's signature Telescopic Linear Side-impact Protection means a bar extends from the side of the seat to the passenger door, being the first thing to absorb shock upon impact. After that? The car seat's shell absorbs additional impact forces
- The Bump
Installation with the vehicle seat belt is pretty easy. I believe in my first review of the original Aton I said it could be the easiest base to install. It might not still have that rank anymore thanks to rigid LATCH, but it’s still pretty darn easy. Thread the seat belt under the belt tensioning plate, remove any slack from the belt, and close the belt tensioning plate.

The base is easy to install and the car seat snaps in and out with ease. My husband likes the proprietary belt tensioning mechanism that works when installing using the latch connectors or seat belt. You simply press down and the lever clicks into place resulting in a snug and secure installation every time. It is also easy to use without a base, in case you need to take the baby in someone else’s car.
- Baby List
LATCH installation is quite easy with this seat and explained well in the manual and with online instructional videos. Some customers have even commented that it is easier to put the child into this seat than in other seats. It can also safely be used with or without the base.

​Excellent side-impact protection and other safety features make the Cybex Aton 2 one of the safest infant car seats available
- Kids Sitting Safe
What experts didn't like
Tensioning plate can be hard to close with too much tension in the belts LATCH strap can interfere with closing the tensioning plate when installing with vehicle belts
- Consumer Reports
We couldn't readily tell why, but it is harder to pull the strap at the foot of the carrier and the padding on the shoulder straps causes additional trouble, and we couldn't get the harness tight enough for smaller babies.
- Baby Gear Lab
And there’s the issue that the plate doesn’t act as a lockoff so you still need to lock your seatbelt at the retractor if your vehicle has this feature.

The cost of purchasing a second base is pricey (about $100 for the base alone). My husband and I both drive our baby around in our cars equally so we have to factor this cost into the total cost of the car seat. If you don’t need a second base, then the price of the Aton is comparable to the other car seats out there.
- Baby List
Parents have noted the chest clip is overly wide, which can be uncomfortable for some babies, while the canopy is too small to offer much sun/weather protection.

The seat features the same unique base tensioning system as the others and is quick and easy to install by clicking it onto the base. However the base itself does not feature a load leg and the seat doesn't have the L.S.P. System found on the other models. It therefore doesn't score as highly for crash protection.

From The Manufacturer

The Aton builds on CYBEX safety technologies to offer great protection with unique safety features. The Aton Linear Side Impact Protection (L.S.P.) system uses a flexible shell that absorbs energy as well as thick EPS foam protection. The shell and foam work in tandem gradually absorb crash forces and distribute them away from the baby, especially during side-impact collisions. Approved for air travel. Secure European installation without the base uses a unique shoulder belt routing behind the carrier that makes this installation method as safe as using the base with Load Leg. Makes travel in taxis and on vacation safe and simple. Installing the base with the Belt Tensioning Plate makes a secure installation easy to achieve.

An Overview On Infant Car Seats

You’re probably already nervous about your first ride home with your tiny bundle of joy. On top of that, you have to try to pick the best infant car seat from a seemingly endless array of options. From the ease of installation to fabric comfort and whether or not it works with your stroller system, it can be overwhelming, to say the least. It’s simple to break down the basics of what you need in an infant car seat so you can find the right infant car seat for your growing family.

Infant car seats — sometimes called bucket or pumpkin seats — are rear-facing and made for infants and toddlers up to two years old. The height and weight requirements vary from seat to seat but they typically work for babies from around 4 to 35 pounds and up to 32 inches in height. Some seats, like the Chicco KeyFit 30, are preferred for preemies but only go up to 30 pounds and 30 inches. The seat usually clicks into or attaches to a base that stays in the car.

Many infant car seats have a carrying handle and an adjustable shade. They also have various types of cushions and inserts that can be used for the smallest infants and then taken out as your child grows.

The Centers for Disease Control (CDC) and the American Academy of Pediatrics (AAP) recommend that children stay rear-facing at least until two years old or when they reach the height and weight limit for the seat. According to the CDC, using a car seat reduces the risk of injury in a car crash by 71 to 82 percent. Overall, kids may end up using a car seat or booster up to the age of 12, based on their height and weight.

Knowing that their child will be using a car seat for such a long time prompts many parents to opt for a convertible car seat. Unlike the infant car seat, a convertible car seat starts rear-facing and can change its configuration to a front-facing car seat and then finally a booster. They are just as safe as an infant car seat and must meet the same standards. While this option can certainly be budget-friendly and you may be able to keep your child rear-facing longer, there are some trade-offs.

For some, the biggest deal breaker is giving up the ability to easily transfer a sleeping baby in and out of the car while still in the seat. Since convertible car seats are meant to stay in the car most of the time, they also don’t typically work with strollers and don’t have carry handles. And, since they’re larger to accommodate a growing child, they may not fit well in all vehicles. You’ll want to make sure to consider how you’ll be using the car seat and if it’s important for you to be able to keep your child in the car seat when you’re out and about. Many infant car seats work with a complimentary stroller or travel system, like the UPPAbaby Mesa, and you may save money buying this as a package deal.

The most important part of any car seat purchase is safety. Each car seat uses different materials and features, but they all have to meet the same federal safety standards. Some may choose to do additional safety testing, like the Evenflo LiteMax 35, which is rollover tested. There are a few things you’ll want to look out for, such as a five-point harness and a base that clearly indicates when the seat is attached and positioned correctly with a color change or a bubble level like the Chicco KeyFit 30.

Actually installing and using the seat the right way can be stressful for any new parent, so the easier it is to do, the better. The National Highway Traffic Safety Administration (NHTSA) maintains an ease-of-use rating system to help parents find seats that have clear instructions and are easy to install and use. Anything rated 4 or 5 tends to be more intuitive.

All cars are now required to have a LATCH system (which stands for lower anchors and top tethers) that allows you to attach the car seat with clips near the seatbelt base and behind the headrest or seat. It can sometimes be a struggle to make the connectors the right length so the UPPAbaby Mesa self-retracting option may be a major plus if you have to take the base in and out more frequently. 

Finally, it’s important to consider overall comfort, for you and for baby. Look at features like the weight of the car seat, the ergonomics of the carry handle and quality or type of fabric. Infant car seats can vary widely in weight. For example, the Evenflo LiteMax 35 is only 16 pounds, while the UPPAbaby Mesa is 25.5 pounds. That can make a big difference if you plan to tote the seat any distance with your little one inside.

If you live in a warm climate you may want to look for a cooler fabric like breathable jersey found with the Peg Perego Primo car seat.  The UPPAbaby Mesa features moisture-wicking merino wool which is also naturally flame retardant. While buying online can be the most cost-effective and convenient, you may want to go to a store where you can compare the feel of the fabric and other materials.

DYWM Fun Fact

As of 1985, all states finally have laws requiring the use of car seats on the books. But in 1987, only 80 percent of people were using them. It wasn’t until 2003 that all cars we required by federal regulation to be manufactured with LATCH systems (lower anchors and top tethers) for car seats. This helped promote usage by making it easier and more consistent to install car seats.

Still, according to the CDC, car accidents and related injuries are the leading cause of death among children (ages 0-12) in the United States. They also found that in one year, 618,000 children did not use a car seat or booster seat at least some of the time. While there are a number of factors that cause injury in car accidents, the NHTSA did a study that found that 46 percent of car seats and booster seats are misused in some way. Front-facing car seats are the most common misuse, at 61 percent.

The CDC urges the use of car seats as the best way to reduce the risk of injury. In addition to following the recommended stages for car seat use, you can also find a certified child safety technician in your area to get installation instruction and tips one-on-one. The bottom line: it’s better to use a car seat or booster as recommended than not and there are resources to help you install and use your seats correctly.

The Infant Car Seat Buying Guide

  • Any parent or caregiver who has cleaned a car seat mess will tell you how important easy-to-clean fabric is. Even better, look for car seats that allow you to remove the lining or pad entirely and toss it in the washer, like the Evenflo LiteMax 35.
  • If you travel frequently or live in a city where you may need to use your car seat in a taxi or rideshare you may want to opt for an infant car seat like the Peg Perego Primo. It can be used with or without its included base, giving you more flexibility when on the go.
  • You are not alone when it comes to learning how to install a car seat properly. The NHTSA offers free car seat inspection locations (usually at local fire stations) with trained technicians who can show you how to install it and use it.
  • Believe it or not, car seats expire. That’s why it’s not recommended to purchase a car seat from a yard sale or online reseller or reuse one from a friend. Most infant car seats expire in five to six years. Some convertible car seats last up to 10 years. You may be able to find the expiration date on the car seat itself or in the owners’ manual. If you can’t find a date, note the model number and call the manufacturer. Most car seats do end up looking kind of beat up, but the real risk is caused by plastic getting hot and cold repeatedly over the years. This may cause hairline cracks or brittleness that aren’t easy to see, and are very dangerous in a crash.
  • Once you’ve chosen the perfect seat, you also have to make sure you’re strapping in your little one correctly. Straps should be at or below the shoulder without any looseness or slack. Your child may protest but you should only be able to fit a couple fingers behind the strap. The chest clip should be at armpit level in the middle of the sternum. If it’s too high, it could cause neck injury and if it’s too low, your child could be thrown from the car seat.
  • As an added safety precaution you can add a luggage tag or label to the side of the seat with emergency contact info. Include details like your child’s name, parents name, address and phone numbers, pediatrician name and any medical conditions. This way, first responders can find valuable information quickly, in case the parent or caregiver is injured or unable to speak.
