CYBEX Platinum · Infant Car Seat
The CYBEX Cloud S is a rear-facing infant car seat designed for newborns through approximately 24 months (40–87 cm, maximum 13 kg). Combining an ergonomic full lie-flat position outside the car with versatile positioning on the Base S, it supports comfortable journeys from the earliest days.
Its 180° rotation on the compatible Base S, adjustable GrowTech headrest and harness, integrated L.S.P. system and travel-system compatibility make daily travel more convenient. The Cloud S is available in Comfort and Style versions, with premium fabrics and enhanced mesh breathability exclusive to Style models.
Outside the car, the Cloud S reclines to a fully flat ergonomic position for carrying or use on a compatible stroller. On Base S inside the car, it offers semi-reclined and upright settings. Its backrest and leg rest move together to distribute your baby’s weight and help reduce forward head tipping.
Fourteen headrest positions, an automatically adjusting harness and removable growing pads help the Cloud S adapt as your child grows. The newborn inlay provides integrated head support, while the seat is designed to support a hip-friendly M-position.
The L.S.P. system directs side-impact forces into the energy-absorbing seat shell and headrest. CYBEX reports up to 25% greater side-impact protection compared with the same seat without L.S.P., based on internal testing.
When installed on the Base S with its required adapter, the Cloud S can rotate 180° to help you place your baby in the seat and lift them out more easily, even when the seat is reclined.
The Base S supports the Cloud S infant car seat with the Base S adapter, and can later be used with the Sirona S or Anoris S Airbag. The adapter is supplied with Base S and must be used when installing Cloud S on the base.
With separately available stroller adapters, the Cloud S can connect to compatible CYBEX strollers. Convenient memory buttons help release it from the frame, while its full lie-flat position is available outside the car.
The Comfort model weighs approximately 3.99 kg, while the Style model weighs approximately 4.1 kg. The seat is described as aircraft-certified; check for the “For Use in Aircraft” label and confirm acceptance with your airline before travelling.
Style versions feature two-tone leather-look detailing paired with breathable mesh, inspired by premium automotive interiors. These details are exclusive to Style models.
Ventilation openings in the seat shell support airflow. Style models add innovative 3D mesh fabric that helps regulate moisture and provides up to six times greater airflow than conventional fabric.
An integrated XXL UPF50+ canopy helps shield your baby from sunlight. The mesh window adds airflow and visibility, but the mesh section itself does not provide UPF50+ protection.
CYBEX states that its products undergo testing for restricted substances, including heavy metals, phthalates and flame retardants, through accredited internal laboratories.
Base S (recommended): ISOFIX and load leg. Cloud S requires the Base S adapter supplied with the base. Check vehicle compatibility.
Vehicle belt: May be installed without a base using a suitable vehicle 3-point seat belt. Follow the user guide every time.
Fabric covers and newborn inlay can be machine washed on a delicate cycle at up to 30°C. Do not machine wash the car seat itself. Follow the user guide for cleaning and maintenance.
¹ Up to 25% greater side-impact protection compared with the same seat without L.S.P., based on CYBEX internal testing. ² The canopy's mesh window is not UPF50+.
The newborn inlay has to be removed when your infant reaches a height of 61 cm (corresponding to approximately 3 months). This ensures that your growing baby has enough space in the car seat.
Yes, your infant car seat can be installed in a car without using a base: In this instance, the car seat is installed using the vehicle belt. This is useful when travelling in a taxi or a second car. However, CYBEX recommends using the infant car seat in conjunction with the base as it makes the handling easier and helps ensure it is installed correctly. If installing the infant car seat on the front passenger seat, it is important to ensure that the front airbag has been deactivated.
When this infant car seat is used in conjunction with a base, it can only be installed either in i-Size approved vehicles or in vehicles with ISOFIX anchorage points. If you are installing the car seat with the vehicle’s 3-point belt, ISOFIX anchorage points are not required. Before purchasing the seat, please refer to the Car compatibility list on the CYBEX website to see whether or not the car seat is compatible with your vehicle.
The infant car seat can be used in a full lie-flat position when attached to the stroller. It can be used in a semi-recline position when connected to the base inside the car but should only be used in an upright position when secured by the vehicle’s seat belt.
No, the Cloud S can only be used with the Base S in combination with the Base S adapter. Once your child has outgrown the infant car seat, the adapter can be removed to use the follow-up seat. Simply rotate the adapter to the boarding position, then remove it by pressing the release button and simultaneously lifting the adapter. Please refer to the User guide for further guidance.
No, according to the UN Standard R129 children have to travel in a rear-facing position until they are at least 15 months old. This is because your infant’s spine and neck muscles have not yet developed sufficiently to cope with the heavy strain of a front collision. If the child is travelling in a rear-facing position, the forces of an impact are distributed evenly over the large area of the car seat shell. The strain on the neck, head, and chest is significantly reduced, reducing the risk of injury when compared to a forward-facing car seat. While the minimum requirement for rear-facing travel is up until the child is 15 months old, given the current state of child restraint technology CYBEX recommends keeping your child rear-facing for as long as possible. To this end, this seat is designed to only be used in a rear facing position.
Yes, both are washable. CYBEX recommends using a delicate wash cycle and a maximum temperature of 30 degrees Celsius. Detailed instructions can be found in the User Guide.
It is important to check whether the car seat is compatible with your vehicle before you purchase it. The car seat is approved for use in i-Size compatible vehicle seating positions as indicated by vehicle manufacturers in their vehicle User Guides. If your vehicle does not have an i-Size seating position, please check the Car Compatibility List. To access the Car Compatibility List, follow the relevant weblink in the Quick Start Guide, printed on the packaging box or find it on the product page of the CYBEX website. If vehicle is not listed, please contact CYBEX Customer Service for further assistance.
You can determine if your car seat is aircraft approved if it has the TÜV Rheinland seal with the reference “For Use in Aircraft”. Car seats with this seal are specifically tested for safety and use with a two-point harness system, as found in an aircraft. Please note, that not every airline recognizes this seal as valid, therefore it is essential to refer to your airline’s regulations to confirm whether you can use your seat, even if the seat has the seal of approval.
Rear-facing car seats must only be installed on the passenger seat if the front airbag has been deactivated. Placing your child on a passenger seat with an activated airbag poses an enormous risk of injury, and CYBEX strictly advises against this. For other types of car seats check the user manuals of both your car seat and your vehicle to find out if you should deactivate the airbag. Statistics show that the safest place for a car seat is on the rear seat behind the front passenger seat. Side airbags do not put your child’s safety at risk. If you have no choice other than to use the front passenger seat, please ensure that the seat is pushed back as far as possible and that the airbag is deactivated.
For safety reasons, CYBEX recommends keeping the handle in the upright position when the car seat is used in the car. For older children above 76 cm, the handle can also be folded in the position behind the backrest and above the LSP when the child is sitting in the upright position. Please ensure that the handle is never in the position below the LSP while driving.
CYBEX strongly recommends replacing a car seat after any kind of accident. This is because tiny hairline cracks, which may not be visible to the naked eye, can appear in the plastic parts of a car seat after an accident. These cracks can pose an increased risk to safety.
