Cybex Aton G Swivel: The Swivel Infant Car Seat

The Cybex Aton G Swivel makes everyday life with an infant a little easier without compromising on safety. Its 180-degree swivel base lets you get your baby in and out of the car with ease—no more awkward angles or back strain. Weighing just 9 pounds, the Aton G is lightweight and easy to lift, carry, and move between vehicles.

Safety is front and center. The seat features Linear Side-Impact Protection (L.S.P.) to help reduce forces in a side collision, plus an integrated anti-rebound bar to limit seat movement during impact. SensorSafe technology adds another layer of reassurance by sending alerts if your child unbuckles, the temperature in the car gets unsafe, or the seat is left occupied.

Thoughtful design details make life simpler for parents. Built-in ventilation keeps baby comfortable, the harness adjusts easily with the headrest, and a UPF 50+ canopy provides sun protection.

Rotating or Reclining Infant Car Seat?

Cybex Cloud Reclining Seat Comparison: Cloud T vs. Cloud G Pro

While the Cybex Cloud T and Cloud G Pro look very similar at first glance, the key differences come down to finishes, safety updates, and recline functionality. The Cloud T features more premium fabrics and refined details, giving it an elevated look designed to pair seamlessly with Cybex Platinum strollers like the Priam. It also offers a smoother, more intuitive recline mechanism, making adjustments quick and easy when transitioning in and out of the car.

In addition, the Cloud T reclines further when used on a compatible stroller, offering a more lie-flat position for on-the-go comfort. The Cloud G Pro does not recline as much, making the Cloud T the better choice for families who prioritize maximum recline outside of the car.

The Cloud G Pro, on the other hand, closely mirrors the Cloud T in design and functionality but stands out by meeting the newest FMVSS 213 frontal and side-impact safety standards. For families focused on the latest safety regulations, this update is a key consideration when choosing between the two models.

Cybex Infant Car Seat Stroller Compatibility

Stroller compatibility is essential, especially in those early months when your baby naps frequently. Being able to quickly click the car seat in and out of the stroller makes errands easier and keeps your routine running smoothly.

All Cybex infant car seats work seamlessly with Cybex strollers, which include the necessary adapters for instant integration. For other stroller brands, a separate adapter may be required.

The Cybex Cloud and Aton series also offer versatile compatibility with many other top stroller brands. They pair with models that support universal Maxi-Cosi style adapters, including Baby Jogger, Bob, Britax, Bumbleride, Bugaboo, Joolz, Mima, Orbit Baby, Peg Perego, Quinny, Romer, Silver Cross, Stokke, Thule, UPPAbaby, and Veer. Contact us anytime if you need clarification on a specific stroller model.

Cybex Infant Car Seat Installation

Installing any of these Cybex infant car seats is simple and straightforward. Like most infant car seats, each includes a base that stays in the car for convenient everyday use—just click the seat in and out as needed. All Cybex infant car seat models can also be installed without the base, making them especially handy for travel, ride shares, or quick trips in a second vehicle. 

Installing the Cybex base for the  Cloud G Pro and Cloud T is as easy as locating your car’s ISOFIX latch anchors and clicking in the base’s rigid connectors. Watch this video to see just how simple it is to install the Cloud T base:

Since the Aton G2 and Aton G Swivel does not use rigid latch connectors, its installation is slightly different, but still quick and easy:

Safe, Chemical-Free Materials in Cybex Infant Car Seats

No Cybex infant car seats are made without added flame-retardant chemicals. Instead of relying on chemical treatments, Cybex meets all federal flammability standards by using carefully selected, high-quality fabrics and materials that are naturally flame resistant.

Models like the Aton G2, Cloud G Pro, and Cloud T take this commitment even further with GREENGUARD Gold Certification. This means the materials have been independently tested and certified for low chemical emissions, helping support healthier air quality around your baby. GREENGUARD Gold standards limit exposure to hundreds of volatile organic compounds (VOCs), making these seats a thoughtful choice for families focused on safety and wellness.

With Cybex, you can feel confident knowing your baby’s car seat is not only rigorously crash tested, but also designed with cleaner materials that support a healthier environment from day one.
