CYBEX Sirona Si i-Size 360° Car Seat with ISOFix Base - Amber Brown - Style

UP TO 50% HIGHER SAFETY LEVELS*
Meet rear-facing travel at its very best; keep your little one safe and snug for the first 4.5 years with the Sirona
Si car seat. Its padded shell acts like a protective shield, cleverly distributing impact forces and holding your
child close. With rear-facing mandatory until 15 months, it provides up to 50%1 better protection until they
turn 4.5.

MADE TO GROW UP TO 4.5 YEARS OLD
Cybex GrowTech has been specially developed so that our seats grow and adjust with your child. A newborn
as an accessory and comfort inlay allow it to be used from birth until they are 4.5 years old (40–105cm).
AGR-certified for better ergonomics, it offers an adjustable headrest, M-position, and 40% more recline range
in both rear-facing and more upright forward-facing** seating. Safe, comfy, built to seamlessly adapt as your
child journeys from birth to young child.

25% MORE SIDE PROTECTION**
Advanced Linear Side-impact Protection is part of a three-tier safety system that cuts impact forces by up to
25%*** by channeling energy into the car seat’s energy-absorbing shell and headrest. The integrated L.S.P
folds out with a simple push during setup and tucks neatly away when space is limited.

3 MONTHS - 4.5 YEARS
Three cleverly designed, removable inlays let you use the Sirona Si car seat from Day one. The Newborn
insert and Newborn inlay are purchasable accessories and are for babies measuring 40 to 60cm, giving them
the extra head and body support they need for a safe, snug fit. When your baby is no longer a newborn but
still small, remove the Newborn insert and inlay but keep the Comfort inlay until they are 85cm tall. This soft,
adaptive layer cushions and supports them as they grow and is included with the Sirona S car seat.

360° ROTATION
Smooth one-handed 360° rotation eases the strain on parents’ backs when placing your child in or taking
them out of the car from the side. The rigid crotch pad provides easy and simple onboarding — quick and
ergonomic for both parent and baby.

BELT HOLDERS
Clever magnets secure the buckle tongues to the sides of the Sirona Si, keeping the belts neatly tucked
away as you place your child in or remove them from the car seat. This streamlined entry creates a calm,
effortless experience for both parent and child.

OPTIMAL BREATHABILITY
All-round air ventilation keeps the child cool and dry year-round. Innovative 3D mesh-style fabric boosts
airflow up to 6× vs. conventional materials. Moisture-resistant fabric and ventilated hard parts guarantee
optimal breathability and comfort. For extra peace of mind, Cybex offers SensorSafe, a child-in-car alert
system that also monitors the car’s interior with an app that sends smartphone notifications.

SUN PROTECTION
XXL integrated sun canopy with UPF50+*** shields your child from the sun, cuts glare for safer naps, and
keeps skin protected on the go. Breathable mesh window boosts airflow for better air circulation. Made
with clever clips, the canopy can be easily detached, giving you the flexibility to adapt for every season,
every trip, and every family adventure. Available in style colours only.

SOFT ON SKIN
Because your child deserves the best start to life, our products are screened for harmful substances such
as heavy metals, phthalates, flame retardants and other restricted chemicals before they reach you. Tests
are done by internal labs and exceed regulatory testing standards in the markets we serve.

LUXURY DESIGN (STYLE VERSION ONLY)
Chic two-tone leather-look accents blend seamlessly with breathable mesh in the new Platinum car seat,
inspired by the finest luxury car interiors. The result is a sophisticated, refined look for you and sumptuous,
secure comfort for your child — style and substance in perfect harmony. Available exclusively in Style
variant.
