Choosing your newborn's first car seat comes down to safety, comfort and how easy it is to live with every day. The Cybex Cloud S i-Size is a rear-facing infant car seat for babies from birth to around 24 months, with added side impact protection and a lightweight 4kg frame that makes carrying it far less of a chore. It is also the starting point of the Cybex Platinum S-Line modular system, so you already have a clear route to the next stage.
Gentle Lie Flat Comfort for Newborns
A newborn's body needs proper support, and the Cloud S is designed around that. Outside the car, the seat reclines fully flat for carrying or strolling, with the backrest and leg rest lowering together. This spreads your baby's weight across a larger surface, which helps reduce pressure on their organs and lowers the chance of their head tipping forward. Once the seat is clicked onto the Base S inside the car, it sits in a semi-reclined position that is more upright than previous generations. A removable newborn inlay with built in head support helps tiny passengers settle into a natural, comfortable position.
A Car Seat That Grows With Your Baby
Babies change quickly in the first two years, and the Cloud S keeps up. Its GrowTech design with width adjustment suits children from 40cm up to 87cm in height. There are fourteen headrest positions, and the harness adjusts at the same time as the headrest, so you get a snug fit without rethreading anything. Removable growing pads help you adapt the seat for longer rear-facing travel, which is the position many parents prefer to keep their child in for as long as possible.
Extra Protection on Every Journey
Safety is built in at several levels. The Linear Side-Impact Protection system channels crash energy into the energy absorbing shell and headrest, and it can reduce impact forces by up to 25% compared with the same seat without it, based on Cybex internal testing. The seat meets the UN R129/04 standard, and the materials are screened for harmful substances including heavy metals, phthalates and flame retardants. That makes it easier to feel confident about what is touching your baby's skin.
Easy to Use at Home and on the Move
Everyday practicality is where the Cloud S really earns its place. When attached to the Base S, the seat turns 180° with one hand, even when it is reclined, which makes fitting, removing and getting your baby in and out much kinder on your back. Weighing just 4kg, it is easy to carry and is airline certified for stress free holidays. The extra large sun canopy has UPF50+ protection (excluding the mesh part), and the breathable mesh window lets you check on your sleeping baby without disturbing them. Air ventilation helps keep your child cool and dry through the seasons.
Ready for the Next Stage
When your baby outgrows the Cloud S, the Base S stays in your car. You can move on to the forward-facing Anoris S Airbag, with its integrated airbag technology, or the rear-facing Sirona S for extended rear-facing travel. With your next baby, you can go back to the Cloud S using the specially designed base adapter. One base and three seats means your investment keeps working for your family for years.
