Cybex sirona s i-size car seat is rated 4.6 out of 5 by 39.
Rated 5 out of 5 by from Made life easy I work as a car salesman so needed a seat that can be used in a variety of cars, the lady in mother care showed me that it can be fitted to all cars that I would potentially drive. The 360 feature is a major advantage and makes putting our son in the car very easy. Unfortunately the seat we bought originally developed a fault where it would not lock into place but was very easily exchanged at the Chester branch.

Rated 5 out of 5 by from Love this car seat My little once has used this car seat from birth and is now 4 and a half month old. In my eyes cybex car seats are one of the most sturdy and safe car seats on the market which was th biggest selling popping for us. My boy always looks really comfy in this car seat and falls asleep once we are no the go. The car seat, fabrics are really good quality, well padded seat. I can easily Buckel my baby in and release the straps to take him out of it. I love the rotation of the seat unit especially as I knew that I needed a c—section but even later on it will do my back good once he gets on the heavy side. My babies head never tilts forward whilst sitting in the car seat even when he is asleep however he still uses the baby insert. We would definitely purchase this car seat again with no regrets.

Rated 5 out of 5 by from Great seat! We bought this seat for our 10 month old after weeks of screaming every car journey in his baby seat! This seat has completely changed our car journeys! Not only do we have no tears but he is happy to sit in it! He can see out of the window and is sat in a better position! We went for the tropical colour and its better in real life!! I love the bright colour! The 360 spin is brilliant making getting baby in and out so easy! The seat is well padded and even has padding around the leg straps! It has a good recline for one baby falls asleep! Overall this is a great car seat and we would definitely recommend it to anyone!

Rated 5 out of 5 by from Strange and comfortable only thing is it’s heavy. Great seat my daughter loves it it’s higher so she can be more nosy and see her mummy better in the mirror. So much easier getting her in and out with it turning to face the door. Love the way it reclines. The only thing I would say is it is heavy and sometimes I have to take it out to leave at her nursery so her daddy can pic her up if I am working late.

Questions & Answers

Hi, I have purchased this car seat from Mothercare, but it doesn’t appear to have any instructions with it. Could you help?  Thanks, Gemma

Asked by: Gemma
I’ve detected my manual underneath the cover when you unzip it at the back of the seat itself. That was in an older version of the seat though but maybe worth a try!
