Description

Advanced child safety protection along with caregiver peace of mind, all in an easy-to-use, convertible car seat—the Sirona M with SensorSafe. Part of the CYBEX Gold Car Seat family, the Sirona M with SensorSafe integrates important safety technology into the chest clip of the car seat to alert when unsafe situations arise.

The Sirona M with SensorSafe 2.0 monitors the well-being of the seated child through the smart chest clip that is synced with the installed vehicle receiver and the caregiver's smartphone. The Sirona M with SensorSafe 2.0 offers an adjustable Linear Side-Impact Protection (L.S.P.) System, which can reduce side impact forces by up to 25% when used properly, and a 12-position height adjustable headrest with integrated no-rethread harness for protection that grows with your child.

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.

In combination with the adjustable Linear Side-impact Protection System, the height-adjustable headrest adds to the excellent side-impact protection of the Sirona M with SensorSafe 2.0 convertible car seat. The length of the harness changes automatically when the headrest is adjusted. This prevents any need for the difficult threading in and out of the harness and makes it almost impossible to misuse.

The 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 it sleeps, which can lead to serious breathing problems. 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. This seat insert is removable after the child reaches 11 lbs., to provide more space and comfort for growing children.

Features:

  • 5-point safety harness with SensorSafe 2.0 Technology integrated in the chest clip
  • Adjustable Linear Side-impact Protection (L.S.P. System) absorbs up to 25% more impact forces in the event of a side impact* (*when compared to the same car seat without L.S.P. extended)
  • Magnetic belt holders for easy entry and exit from the seat
  • Rear-facing installation from 5 lbs. to 40 lbs., or Forward Facing from 22 lbs. to 65 lbs.
  • Energy absorbing shell helps reduce the forces felt by the baby in a collision
  • 12-position, height-adjustable headrest with an integrated no-rethread harness for protection that grows with your child
  • 10-position one-hand adjustable recline for the best fit to your car
  • Cup holder can be positioned on either side and is dishwasher safe for easy clean up
  • Cozy harness pads with anti-slip backing and comfort padded buckle cover

  • Removable newborn insert provides support from 5 lbs. to 11 lbs
  • Install using LATCH or the vehicle seat belt for a safe and secure connection to the vehicle seat
  • Dual Belt adjusters to ensure a tight fit
  • Dual-level indicators to help ensure the proper angle
  • Innovative one-pull LATCH removal system
  • LATCH Connection storage provided in the seatback when not in use
  • Ergonomic design in CYBEX’s iconic Gold Design language
  • Designed and engineered in Germany

Sensorsafe 2.0

Originally developed to help prevent the rising number of infant hot car deaths, SensorSafe 2.0 will chime through the installed vehicle receiver to alert when a child is still secured in the back seat after the car has been switched off. This reminds the caregiver to take action quickly, but if the child is still secured after several minutes an alert will be sent to the caregiver’s cellphone through the downloaded app. If the situation is still not remedied, the designated emergency contact will 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, just keep the receiver plugged into your car’s OBD port to drive with that extra peace of mind. 

  • Chimes through the installed vehicle receiver if child is still secured in the seat when the car is switched off
  • Alerts through the caregiver’s cell phone if the child is left behind in the vehicle and then alerts the designated emergency contact if the situation is still not remedied
  • Emergency contact receives GPS coordinates of the vehicle’s last known position
  • Alerts through the vehicle receiver and caregiver’s smart phone when the child has unbuckled themselves while the vehicle is in motion
  • Monitors the back seat temperature to alert through the vehicle receiver and the caregiver’s smart phone when the back seat appears to be too hot or too cold for the child’s comfort
  • Provides warnings to the caregiver when the child may have been seated for too long and needs a break
  • Receiver plugs directly into your car’s OBD port and syncs with the caregiver’s cell phone
  • Only one install needed if receiver is kept plugged into vehicle’s OBD port
  • Helps to prevent misuse by providing guidance on installation, how-to videos, FAQ’s, direct link to customer service and more through the Sensorsafe 2.0 app.
  • App can monitor up to 16 chest clips on a single platform
  • App download available for Android and IOS

Underwhelmed
March 20, 2023
I honestly expected better. I have the Cybex carriage and I am in love with it so I was excited to get the Cybex but I was underwhelmed. It was uncomfortable for my two year old. There didn't seem to be much wiggle room to adjust the seat and it was hard to get to the button to adjust since it was close to the seat. It had nice comfy cushioning but overall I wouldn't get it again.

The quality of this car seat far exceeds that if many American brands. We bought this one after having a Cybex infant car seat and probably won't ever get another brand!

Specious
July 21, 2021
We love this car seat, it's open enough for child to look around yet side, head well protected, specious and comfortable. My son is still an infant so it's rear faced, hopefully it will be just as comfortable front faced. Looking forward for it to serve well and last long.

Not the quality I was expecting
June 15, 2021
I was very excited about this seat. We got the matching booster for our older child also. But I just was not impressed by the quality or the feel of the seat. The sensor safe clip is also kind of annoying to undo. We have to bring my baby to urgent care and I was trying to get him out of the seat and needed two hands to do so.
For comparison my older child had a maxi cosi seat and in our other car for my youngest we have the uppababy Knox seat. Concidering the price on this cyber seat and having had used a cybe infant seat I was surprised by how the material and the seat overall felt relatively cheap.
The sensor safe is a cool option though as it dings a little song when you turn the vehicle off.
I think overall this would be a great extra seat for a car baby isn't in all the time. 1 because it's not terribly comfortable feeling and 2 the sensor safe is a nice feature incase you didn't often have the baby with you.
Pros
  • Sensor safe is neat!
Best Uses
  • As an extra seat for a car your child isn't often in
Cons
  • Feels cheap and uncomfortable

Kept my daughter safe.
March 7, 2020
I bought this car seat a year and a half ago after reading reviews for months. I wanted the safest one. Well, my worst fear came true last week when we were in a bad head on collision going 50 mph. This car seat kept my daughter safe and protected as two cars crumbled. I can't imagine buying a different one now.

Great! We are using The Sirona M in rear position with a newborn. It took time to fix it in the car with the Belt, but finally it works! I am happy!
Pros
  • The manual or tutorial from Cybex should explain more about newborn ant the Sirona M, and working with the Belt.

Comfortable but difficult to install

My son likes this seat, but the straps do cut across his thighs. It is also difficult to get a good install in our Suburban. We have to use the seatbelt and lock off to install in the Suburban.

The texture is nice and soft. It is also cool which is a huge bonus for the California summer.
The space in the car seat is larger than Graco, so the baby feels more free in it.

Sensor Piece of Mind
March 28, 2019
We have found Cybex with our first daughter and now that I am 4 days overdue with my second baby they too will be in Cybex soon. The reason we chose this was because of the sensors. My daughter was an escape artist and we would get to our destination only to find she was practically out of her seat due to the clips in other types of car seats. I wanted that piece of mind and the ability to pull over quickly if she was able to break free.

Good Carseat
November 20, 2018
My little one seems to be comfortable in the car seat.
I like the sensorsafe technology. It tells me when the seat is buckled or when the kid is left in the car after the engine is off.
It was a little hard to install and the instructions are not easy. I wished they had a video of how to install.
My only 1 complaint is that the seat belt somehow seems to get longer on the right side.
Pros
  • good looks
  • comfortable
Cons
  • hard to install

Not as impressed as its infant car seat cloud q
June 5, 2018
For those of you who have cloud q and expect to get premium quality convertible car seat, this is NOT something you want to get. The material is ok but not nearly as good as cloud q. I had nuna rava for my older kid which is significantly better than sirona in terms of quality. For example the headrest feels really hard and seems there is very little cushion. But I can't really compare them given close to $200 price difference. Overall a fair product. I guess it priced right but I'm a little disappointed.

As the mom of 4 children, I've had many car seats and this one is by far my favorite. My 8 month old son loves this seat - its like his own little recliner and he never fusses when I put him in it.
Pros
  • The multiple incline positions
  • Very easy to attach to the car
  • First straps Iâ

How easy is to remove the cover to wash the car seat?
The cover of the Cybex can be removed to machine wash in cold water. The nicer finished look of the fabric being tucked under the shell makes it a little more difficult to remove the cover, but it is worth the effort.
