The CYBEX Cloud S is a premium i-Size infant car seat designed to provide exceptional safety, comfort and ergonomic support from birth to approximately 24 months. Offering a full lie-flat position outside the car, 180° swivel rotation when paired with the CYBEX Base S, GrowTech adjustment and advanced side-impact protection, it is designed to grow comfortably with your baby from their very first journey.
Designed with the safety and comfort of newborns in mind, the CYBEX Cloud S combines outstanding ergonomics with clever features that make everyday journeys easier for parents.
Suitable from birth to approximately 24 months, for children measuring 40-87 cm and weighing up to 13 kg, the Cloud S provides flexible positioning as your little one grows. Outside the car, it can recline into a full ergonomic lie-flat position for strolling or carrying. When installed on the compatible CYBEX Base S, it provides both semi-reclined and more upright positions.
As the seat reclines, the backrest and leg rest flatten simultaneously to spread your baby's weight over a larger surface. This helps reduce organ compression and helps prevent your baby's head from tipping forward, supporting a comfortable and healthy posture during those important first two years.
CYBEX GrowTech provides 14 headrest positions, with the harness adjusting simultaneously as the headrest is raised. Removable growing pads and the newborn inlay with integrated head support help create an appropriate fit as your baby develops, while the seat shell is designed to support a hip-healthy M-position.
When paired with the separately available CYBEX Base S, the Cloud S becomes a convenient 180° swivel rotating infant car seat. One-handed rotation allows the seat to turn towards the car door for easier on and off-boarding, helping to reduce bending and back strain for parents.
For added protection, the Linear Side-impact Protection (L.S.P.) System channels collision forces into the energy-absorbing shell and headrest. CYBEX states this increases side-collision safety by up to 25% compared with the same seat without L.S.P., based on internal testing.
Weighing approximately 3.99 kg for the Comfort model or 4.1 kg for the Style model, the Cloud S is also designed for easy carrying and is airplane-certified, making it a particularly versatile option for family travel.
Please note: CYBEX Base S, stroller adapters and other compatible accessories are available separately unless specifically included as part of a bundle.

With CYBEX Base S
For convenient ISOFIX installation, the Cloud S can click onto the separately available CYBEX Base S. The Base S installs in the vehicle using ISOFIX and a load leg for stability.
The Base S is also what enables the Cloud S's 180° rotating swivel functionality and in-car recline positions.
A Base S Adapter is required to install the Cloud S, with CYBEX stating that the adapter is supplied with the Base S.
With Vehicle Seat Belt
If your vehicle does not have ISOFIX, the Cloud S can also be installed without the Base S using the vehicle's seat belt. The vehicle belt is secured around the infant car seat and must be correctly refitted whenever the seat is removed and reinstalled.
The Cloud S and Base S form part of the CYBEX Modular System, giving parents greater flexibility as their child's car seat needs change.
After the Cloud S, the same Base S can support a transition to either:
This also makes the system practical for growing families, as the Base S can later be used with the Cloud S again for a new baby.
