Cybex Aton G Swivel: The Swivel Infant Car Seat

The Cybex Aton G Swivel brings next-level innovation to everyday convenience. Designed with both safety and ease of use in mind, this infant car seat features a 180-degree swivel base that makes getting your baby in and out of the car simpler than ever—no more awkward angles or straining your back. Despite its advanced features, the Aton G remains lightweight at just 9 pounds, making it one of the easiest carriers to lift, carry, and transfer between vehicles.

Safety is at the core of the Aton G’s design. It includes Linear Side-Impact Protection (L.S.P.), which helps reduce crash forces in a side collision, and an integrated anti-rebound bar to minimize seat movement during impact. The SensorSafe technology adds extra peace of mind by sending Bluetooth alerts if your child unbuckles, the car becomes too hot or cold, or the seat is accidentally left occupied.

Other thoughtful touches include built-in air ventilation, a no-fuss harness system that adjusts with the headrest, and a UPF 50+ canopy for sun protection. The Aton G Swivel is a perfect choice for parents seeking a balance of safety, smart technology, and effortless usability in a compact, modern design.

Cybex Cloud T: The Platinum Reclining Infant Car Seat

The Cybex Cloud T infant car seat is where safety meets serious comfort and style. The Cloud T is part of Cybex's platinum line and for good reasons. It’s one of those car seats that feels just as good as it looks—tested to the highest standards and designed with parents (and babies) in mind. Every detail feels elevated, from the buttery-soft, chemical-free fabrics to the thoughtful safety features that go the extra mile for peace of mind.

The Cloud T isn’t just about getting from point A to B. It’s about keeping your baby safe and comfortable the whole way there. The SensorSafe chest clip connects to your phone for smart alerts, while the load leg and anti-rebound base work together to reduce crash forces.

Reclining Seat Showdown: What are the biggest differences between the Cloud T and Cloud G Lux?

When it comes to the Cloud T and Cloud G Lux, the biggest difference is in the details. The Cloud T features more premium fabrics and finishes, giving it that elevated look and feel to match Cybex’s Platinum strollers like the Priam. Cybex also refined the recline function on the Cloud T, making it smoother and easier to adjust—perfect for quick transitions in and out of the car.

The only other distinction is in weight capacity: the Cloud G Lux tops out 5 pounds more than the Cloud T. That said, most little ones will reach the height limit well before they hit the weight limit, so it’s not something most parents will notice in everyday use.

Stroller Compatibility

Stroller compatibility is key—especially in those early days when your baby seems to nap around the clock. The ability to quickly click the car seat in and out of the stroller makes errands much easier and less disruptive.

All three Cybex infant car seats are compatible with the same stroller models. Cybex strollers include the necessary adapters for the Aton and Cloud series, while other stroller brands will require a separate adapter purchase.

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 three 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 Lux 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 G Swivel does not use rigid latch connectors, its installation is slightly different—but still quick and easy:

Materials: Do Cybex infant car seats contain flame retardant chemicals?

No—none of the Cybex infant car seats contain added flame-retardant chemicals. Instead, Cybex meets federal flammability standards by using high-quality fabrics and materials that are naturally flame-resistant.

The Cloud T goes a step further with GREENGUARD Gold Certification, meaning it has been independently tested and certified for low chemical emissions. This certification, granted by UL GREENGUARD, ensures that the materials meet strict standards for indoor air quality—limiting the emission of over 360 volatile organic compounds (VOCs) and total chemical emissions.

This commitment to safety and sustainability means your baby rides in a seat that’s not only rigorously crash-tested, but also made with cleaner, healthier materials.
