The Cybex Sirona M is a convertible car seat that combines a sturdy build, ease of installation, and some high-tech safety features. You’ll have peace of mind knowing it’s equipped to automatically alert you to potentially unsafe situations, by way of sensors built into the seat’s chest clip.
It’s also got an energy-absorbing shell and linear side-impact protection. In addition, your little one will ride in comfort, thanks to a 10-position reclining backrest and a cup holder that can be attached to either side of the seat. When the weight and height guidelines are followed, this model is generally suitable for children from birth through around four years of age.
Among other accolades, the Cybex Sirona M received a “Best in Show” distinction from the Juvenile Products Manufacturers Association’s Innovation Awards in 2018.
Overview of Cybex Sirona M
This convertible car seat is designed for kids ranging from five to 65 pounds in weight and up to 49 inches in height. Both new and seasoned parents can appreciate the automated alerts that are generated by a chip in the harness clip and sent to your smartphone regarding your child’s safety. It can detect situations such as when the chest clip becomes unbuckled during car rides, when the ambient temperature climbs above a certain level, and when you’ve possibly left your child behind in the car seat after exiting the car.
Additional safety features include energy-absorbing foam and a pop-out component that help provide linear side-impact protection. It’s also easy to install and uninstall, due to sturdy LATCH connectors, a one-pull LATCH removal system, a no-rethread harness, and level balls that let you know when the seat is at the proper angle for rear- and forward-facing modes.
To make cleaning the Sirona M easy, the fabric seat cover, shoulder pads, buckle pad, and infant insert can be placed in the washing machine. Note, however, they do need to be line-dried. The removable cup holder is dishwasher-safe.
Overall, this seat comes very highly regarded: In addition to the aforementioned JPMA award, in 2018 the Sirona M also received the Best of Baby Tech Award from Babylist and the Best Convertible Car Seat distinction by The Bump.

Cybex Sirona M Car Seat vs. Evenflo Gold SensorSafe EveryStage Convertible Car Seat
A similar enough car seat to the Cybex Sirona M is the Evenflo Gold SensorSafe EveryStage Smart All-in-One Convertible Car Seat. Both are equipped to notify you automatically of likely unsafe conditions. One big difference, however, is the EveryStage offers three modes, whereas the Sirona M only provides two. As such, the EveryStage can be used longer since it can be converted into a booster seat as your child grows and no longer needs a five-point harness. Otherwise, the two share some key characteristics in addition to the SensorSafe technology, such as no-rethread harnesses, 10 adjustable recline settings, and easily adjustable headrests.
In addition to your ability to use the Evenflo model considerably longer, it’s also sold at a significantly lower price, which can make it a more attractive option for anyone who wants the SensorSafe technology but at a more budget-friendly cost. Both have been tested rigorously for safety and meet or exceed federal safety standards.

Conclusion
It is typical for parents to come across car seat options that look great at first glance. The Cybex Sirona M with SensorSafe 2.0 convertible car seat has many features that provide comfort and ease of installation. But, it has disappointing crash test results.
The Sirona M does take crash precautions with its SensorSafe technology. One of the benefits of those sensors is protecting your baby from heatstroke by alerting you. But, it is not enough to earn high crash test scores.

The ease of use and installation for the Sirona M is on point. The LATCH system is easy to use. However, it is a fair bit harder to install if you choose to use your vehicle seat belt. It has a no-rethread harness, so you do not have to fight with the convertible seat every time you need to make an adjustment.
The Cybex Sirona M with SensorSafe 2.0 is expensive and bulky. It is likely not the right choice for you and your precious cargo. The width makes it difficult to have more than one backseat passenger, too.
