The Innovative 360° rotation technology makes on and off-boarding simpler for parents. It also makes it easier to switch to forward-facing travel after 15 months (76cm). Once onboard, the all-round ventilation system keeps them cool and comfortable.
A cleverly integrated Linear Side-Impact Protection System gives streamlined, reinforced protection in side collisions. As part of the Modular G family, the Base G ISOFIX base (sold separately) fits the Sirona G i-Size for use till approx. 4 years old.
Key features include up to 50% higher safety levels in rear-facing position, easy on and off boarding with 360° rotation, grows with your child up to 4 years old, side impact protection, one hand recline with 5 settings, easy installation with load leg and ISOFIX, and breathability with ventilation holes.
Safety notes: Under no circumstances should a rearward-facing car seat be used on a passenger seat with an active airbag. Correct fitting is paramount. Not all car seats fit all cars; check suitability. Always read the instruction booklet. Babies shouldn't be left in car seats for prolonged periods.
Suitability: Check the car seat is suitable for your car before ordering. Some shops offer car seat fit tests. All car seats meet R129 (iSize) safety regulation. A baby must travel rear-facing up to 15 months. Some seats can be used rear-facing until 105cm tall (around 4 years). Side impact testing is assessed as part of the regulation.
