CYBEX Cloud S Baby Car Seat with Base S Rotating Base

CYBEX Cloud S i-Size Infant Car Seat and Base S Rotating Bundle

Everything you need for your baby’s first journeys, in one box. This bundle pairs the CYBEX Cloud S infant car seat with the Base S, the rotating ISOFIX base at the heart of the new Platinum S-Line. Approved to UN R129/04 (i-Size), the Cloud S keeps your little one rear-facing from birth up to approx. 24 months (40–87 cm, max. 13 kg), while the Base S stays in your car for years to come. It’s one of the most complete starter systems in our baby car seats range.

Choose Comfort or Style

The Cloud S comes in two fabric finishes. Comfort is soft and practical, in Cozy Beige or Sepia Black. Style is inspired by luxury car interiors, with two-tone leather-look accents, breathable 3D mesh that boosts airflow by up to six times compared with conventional materials, and an XXL sun canopy. Style is available in Sepia Black, Amber Brown, Misty Grey, Opal Blue, Quartz Pink, Jade Green and Off White. Both versions share exactly the same safety features.

180° rotation with one hand

Once the Cloud S is clicked onto the Base S, it turns 180° towards the car door with one hand, even when reclined. No more twisting or awkward lifting over the door frame: you can settle your baby, tighten the harness properly and turn them back to face the rear in seconds. It’s a real help for parents recovering after birth, or anyone juggling a baby and bags.

Confidence in every installation

A car seat can only protect your baby if it’s fitted correctly. The Base S uses ISOFIX connectors and a height-adjustable load leg for a rigid, stable connection, with colour-coded ISOFIX release buttons to guide you. LED safety indicators show the status of the ISOFIX, load leg, impact shield and battery, so you can check everything is right at a glance before you set off.

Designed around your newborn

The Cloud S reclines fully flat outside the car, with the backrest and leg rest flattening together to spread your baby’s weight and help minimise organ compression. On the Base S, it moves between a semi-reclined position and a more upright one. CYBEX GrowTech with width adjustment, 14 headrest positions, a removable newborn inlay and Linear Side-Impact Protection (L.S.P.), which increases side-impact protection by up to 25%*, keep your baby safe and supported as they grow. At just 4 kg, the seat is light to carry and certified for use on aircraft. Style variants add an XXL UPF50+** sun canopy with a breathable mesh window.

One base for the years ahead

Buying the Base S now means you’re ready for the next stage. When your baby outgrows the Cloud S, the same base takes the CYBEX Sirona S Rotating Toddler Car Seat for extended rear-facing travel up to 4.5 years, or the CYBEX Anoris S Airbag Car Seat. If you’d prefer to buy the parts separately, you’ll find the CYBEX Cloud S Rotating Baby Car Seat and the CYBEX Base S 360° Rotating ISOFIX Car Seat Base on their own pages. The CYBEX Sirona Si Rotating Toddler Car Seat and CYBEX Anoris Si Airbag Car Seat each have an integrated ISOFIX base built in, so there’s no separate base or adapter to buy. As the UK’s extended rear-facing specialists, we’ll always help you keep your child rear-facing for as long as possible with the best advice.
