Cybex Sirona G i-Size 61-105cm (9-18kg) Plus Lava Grey

• Designed for children from approximately 3 months to 4 years of age, suitable for height 61–105 cm and weight up to 19–20 kg (or from 40 cm with an additional newborn inlay).
• Complies with UN R129/03 (i‑Size) regulations.

360° Rotation System

• When used with the separate Base G (not always included), the seat can rotate 360°, making it much easier to place or remove the child — it can be done with one hand, even in reclined position.

Safety

• Up to 50% higher safety in rear-facing position compared to forward-facing in frontal collisions.
• L.S.P. Plus – Linear Side-impact Protection, together with the energy-absorbing shell, reduces side-impact forces by up to 15%.

Comfort & Ventilation

• Full ventilation: built-in air channels throughout the seat shell ensure improved airflow.
• In the “Plus” version – additional mesh fabrics increase air permeability up to 6 times compared to standard fabric covers.

Adjustment & Ergonomics

• 5 to 12 adjustable headrest height positions, with automatic strap length adjustment using one hand.
• Five recline positions, both forward and rear-facing (allows semi-reclined seating).
• Integrated belt holders keep the harness out of the way when seating the child — reducing tangling hassle.

Specifications

• Dimensions with base: approx. 710 × 440 × 750 mm.
• Weight: approx. 6.5 kg without the base, about 13 kg with Base G.
• Fabric care: machine washable on a gentle cycle up to 30 °C, air dry only.

Awards & Reliability

• Recognized as safe by ADAC, praised for ergonomics (AGR certified), and awarded for design (Red Dot Design Award).
