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

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.
  • Sensor safe is neat!
Best Uses
  • As an extra seat for a car your child isn't often in
  • Feels cheap and uncomfortable

El color Pom! S?per f?cil de instalar y con acabados s?per delicados , el sensor safe muchas veces se vuelve molesto al ser tan insistente en las alertas pero pufff para eso est? dise?ado Jajajja... cada centavo invertido en este producto vale la pena .

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.

If your going to purchase something one time for your child, this car seat would be your go to. High quality material and super safe. MY toddler girl loves this car seat and has a blast taking naps in it.

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!
  • 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
By Nicolem529
from Colorado
on March 28, 2019
Verified Buyer
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.

This is the most secure and comfort convertible my baby ever try. With an extra side impact security layer I choose it because I also loved the color and design.

Good Carseat

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.
  • good looks
  • comfortable
  • hard to install

Not as impressed as its infant car seat cloud q
By Melvin

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.

We have a foonf, a rava, and this seat. This seat is lighter and more user friendly to install. It seems just as comfortable for our little one as fhe others. However, the materials are not greenguard certified. Overall, a pretty nice car seat.

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.
  • The multiple incline positions
  • Very easy to attach to the car
  • First straps Iā

1 Question & 1 Answer
from Cleveland, OH asked:
February 7, 2018
What is the rear facing height limit of this seat?
We have spoken with Cybex, they have advised that the maximum child height for forward facing is 49". They do not yet have specific info for rear facing, other than the top of the childs head needs to be 1" below the headrest.
