The Cybex Sirona Gi i-Size Plus Car Seat in Lava Grey offers a new level of safety and comfort for modern families. Designed for use from 3 months to 4 years (or from birth with the optional newborn inlay), this car seat combines extended rear-facing security with ultimate breathability and smooth 360° rotation.

Winner of the ADAC Test 2023, the Sirona Gi provides enhanced protection through Linear Side-impact Protection (L.S.P.), an energy-absorbing shell, and easy ISOFIX installation with a support leg. Its extended rear-facing capability up to 20kg helps reduce pressure on your child’s neck and head during a collision—making it one of the safest ways to travel.

With five recline positions, an adjustable headrest, and ingenious harness loops that hold straps out of the way during boarding, the Sirona Gi makes every journey smoother—for both parent and child.
