Thank you to CYBEX for kindly sponsoring this post. All opinions are 100% honest & completely my own.

Life with three boys is pretty hectic, as I'm sure you can imagine (or experience for yourself). I'm on the move most of the day and my to-list is seemingly endless. Suburban life requires us to be in and out of the car all day for carpool and errands and my little guy tags along wherever we go. Therefore, safety is of the utmost importance. I'm always intrigued by the latest car seat safety innovations and excited to report on them because I know how overwhelming the choices are. We've been successfully using the Sirona M with SensorSafe2.0 from CYBEX. We love the brand and have also had a positive experiences with the Cloud Q Infant Car Seat and CYBEX MIOS Stroller.

The Sirona M with SensorSafe 2.0 is the newest addition to the CYBEX Gold Car Seat family. What sets it apart from other car seats is that it integrates safety technology into the chest clip of car seat's harness to alert caregivers when unsafe situations arise. It was originally developed to prevent the rising number of infant hot car deaths but now goes a step further to monitor the well being of the child while the vehicle is in motion. For example, if you accidentally leave the child alone in the car or the child unbuckles herself, an alert will go off through both a vehicle receiver and the caregiver's cellphone via an app (the app is not required to receive alerts).

Here are the highlights of why you should test drive the Sirona M Convertible Car Seat:


The Sirona M is a convertible car seat for use from birth up to 65 lbs. and can be installed both rear-facing and forward-facing. That means you will only ever need this one car seat.  


SensorSafe 2.0 will chime through a vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. It's super simple to install. If the child is still secured after several minutes, an alert will also be sent to the caregiver’s cellphone through an app you can download.

If the situation is still not remedied, a designated emergency contact can receive an alert with the GPS coordinates of the vehicle’s last known position. This state-of-the-art safety technology is designed so there is no need to reinstall each time you drive. For ease, I just keep the receiver plugged into my car’s OBD port to drive with that extra peace of mind. The user-friendly app also provides guidance on installation, how-to videos and FAQ’s to help prevent misuse.

Whether rearward or forward-facing, the CYBEX Sirona M with SensorSafe 2.0 features an adjustable Linear Side-impact Protection system (L.S.P.), increasing the level of safety in case of a side-impact collision. The L.S.P. system can be individually adjusted on the door facing side of the car seat and can absorb up to 25% more impact forces in a side-impact collision in combination with the head and shoulder protectors.

With the 12-position height-adjustable headrest with integrated harness guide, the length of the harness changes automatically when the headrest is adjusted. This prevents you from having to re-thread the harness and makes it almost impossible to misuse.

A Newborn Inlay provides a near-flat angle in the seat of the Sirona M with SensorSafe 2.0, helping to prevent baby's head tipping forward while sleeping. Along with German doctors and midwives, and taking into account the findings of many tests, this function was developed to enable a safe lying angle between head, neck and chest, thus significantly reducing the risk of suffocation. The seat insert is removable after the child reaches 11 lbs, to provide more space and comfort for growing children.  

Other premium features of the Sirona M with SensorSafe 2.0 include a cup holder, an energy absorbing shell to reduce impact in the event of a collision, a one-hand adjustable recline with 10 positions, a Dual Level Indicator to indicate the correct seat angle in both rearward and forward-facing positions, and magnetic belt holders make it easy to get squirmy babies in the seat! 

Julian is quite cozy in the Sirona M with SensorSafe 2.0, as you can tell from the photos. He had no trouble adjusting to this cushy ride! I'm thoroughly impressed by the technology. It's truly a game-changer for the car seat industry. The Sirona M with SensorSafe 2.0 is easy to install and looks great. The added SensorSafe2.0 makes it one of the best car seat options available.
