About this Car Seat
Installation of the car seat is easy to do thanks to the one-click with the ISOFIX connectors and the visual indicator means it’s easy to see if it has been installed correctly and safely. Then simply extend the leg and you are good to go.
Once the seat is installed, a simple press of a button allows you to rotate the seat. Place the seat in the entry/exit position, facing the door, to allow you to place your child in the seat easily and without breaking your back.
Don't forget, this seat is extended rear-facing, meaning that you can leave your child rear-facing all the way up to 105cm (approx. 4 years old) as experts advise this is the safest way for them to travel.
The Sirona SX2 features special Energy Reduction Technology, which helps to reduce the strain on your child's neck if they are facing forwards and the vehicle is involved in a head-on collision. It works with an innovative harness design that reduces the forces on the neck by up to 20% compared to other harness systems.
The seat also features integrated Advanced Linear Side Impact Protection – these are small arms that automatically flick out and work in conjunction with the energy-absorbing shell of the seat to reduce those harmful forces by up to 25%.
The seat has a height-adjustable headrest - it moves up to 12 positions, growing as your little one does and the seat also reclines on the base to 5 positions when rearward facing and to 3 positions when forward-facing. For practicality, the Sirona SX2 has a belt holder at the sides to hold the harness out of the way whilst you put your child in the seat.
A separately sold newborn insert is available and will allow the seat to be used from birth.
Fitting instructions, cover removal instructions and other technical information can be found in the manufacturer's instruction manual, located here.
