Pre-ordering secures your seat from Cybex's first deliveries, so it's ready and waiting well before your little one arrives. Dates are Cybex's latest estimates and may change, and we'll keep you updated until your order is on its way.

The CYBEX Cloud S is a lightweight i-Size infant car seat from the new CYBEX S-Line modular system, designed to protect and support your newborn from birth. Its ergonomic lie-flat position gives your baby a naturally flat place to rest out of the car, while 25% more side-impact protection keeps them safe on every journey. The Cloud S clicks securely onto the Base S for a 180° rotation that makes lifting your baby in and out effortless.

Why parents choose the Cloud S

• Ergonomic full lie-flat from day one – outside the car it lies completely flat for strolling or carrying, spreading your baby's weight over a larger surface to reduce organ compression and stop the head tilting forward.
• Lasts up to 2 years – CYBEX GrowTech with width adjustment grows from newborn to approx. 2 years (40–87 cm), with fourteen headrest positions and a simultaneously adjusting harness for a perfect fit at every stage.
• 25% more side-impact protection – the Linear Side-Impact Protection (L.S.P.) system channels energy into the seat's energy-absorbing shell and headrest, cutting impact forces by up to 25%.
• One-hand 180° rotation – on the Base S the seat turns towards the door with one hand, even when reclined, reducing strain on parents' backs.
• Airline certified – at just 4 kg it's lightweight, easy to carry and aeroplane-approved for stress-free travel.
• XXL sun canopy (UPF50+) – shields your baby from the sun with a breathable mesh window so you can check on them without disturbing them.
• Optimal breathability – all-round ventilation and 3D mesh Style fabric boost airflow up to 6× versus conventional materials to keep your baby cool and dry.
• Part of the modular system – three seats, one base: the Cloud S shares the Base S with the rear-facing Sirona S and the forward-facing Anoris S Airbag.

Approved to UN R129/04. Suitable from birth to approx. 24 months (40–87 cm, max. 13 kg). Seat weight 4 kg.
