The latest Cybex Sirona car seat review is here

The Cybex Sirona is a Group 0+/1 seat for newborns to around age four and combines the rear-facing requirement with an option to turn the seat forward-facing, like the Maxi-Cosi 2wayPearl (£375) and Britax DUALFIX (£340).

Is it easy to install?

The seat is relatively straightforward to install, but I needed to ask my husband to carry it down to the car as it is pretty heavy (as I have found are all car seats). It installs using the ISOFIX system and there is a list of cars on the website with which it’s compatible.

If you don’t have ISOFIX then it would mean an extra cost getting the ISOFIX system installed in the car, as this car seat cannot be installed just using a seatbelt.

Also, this is not a seat for moving in and out of different cars with any regularity as it is heavy and cumbersome, but because it has to stay in the car once it’s been installed (so you couldn’t use it as part of a travel system) this isn’t necessarily a problem.

However, we found that after installing it on the driver’s side, we actually needed to move it to the passenger side, as my 6ft 3ins husband couldn’t get his seat back as far as he needed to with the seat in place.

How is it strapping your baby in?

The straps are a five-point safety harness which buckle between the child’s legs and I found them easy to use. A feature that I particularly liked was that the cushioned strap pads are attached using poppers – meaning they are much easier to remove and clean than on other car seats I have used.

What’s in the box?

  • Cybex Sirona car seat group 0+/1
  • Safety cushion restraint
  • Footboard

Any additional extras?

  • Summer cover – £49.95

Made For Mums verdict?


This is a quality product with plenty of useful features – such as the ability to swivel it when getting the baby in and out, lots of recline positions and an adjustable headrest. The high price tag is worth it when you consider it can be used for four years, but it must be used in a car with an ISOFIX system. I would recommend it unless you are hoping to use a travel system and frequently take your seat in and out of the car.
