Pramworld Explains: CYBEX Cloud S vs Cloud T – What’s the Difference?

Posted by Lucy on 15th Oct 2026

Choosing the right infant car seat is an important decision for new parents. With the launch of the new CYBEX Cloud S, you might be wondering how it compares with the CYBEX Cloud T and which features make each model stand out.

Both car seats are designed for babies from birth, with ergonomic positioning, ventilation and practical features for everyday journeys. The new Cloud S introduces a lighter design, additional room for growing babies and updated features to support comfort and convenience.

In this guide, we compare the CYBEX Cloud S and Cloud T to help you understand their key differences.

Meet the new CYBEX Cloud S

The CYBEX Cloud S is designed to combine comfort, adaptability and convenience from birth. With an ergonomic recline, an adjustable design and features for everyday travel, it builds on the Cloud range with several updates.

  1. A lighter design

Weighing approximately 4.0kg, the Cloud S is 10% lighter than the Cloud T. Its lighter design can make carrying the seat between the car and your home more convenient.

  1. More room for growing babies

The Cloud S is 15% wider and features CYBEX GrowTech, designed to adapt as your baby grows. Removable growing pads and an additional 5cm of space provide more room for your little one.

The Cloud S is suitable from birth up to approximately 24 months, for babies measuring 40–87cm and weighing up to 13kg.

  1. Side-impact protection

The Cloud S features the L.S.P. System (Linear Side-impact Protection). CYBEX's launch materials highlight 25% more side-impact protection.

This is a manufacturer-stated feature, rather than a direct comparison proving that the Cloud S is 25% safer than the Cloud T.

  1. Ergonomic positioning

The Cloud S offers individual positioning, from semi-reclined to upright in the car. Outside the car, it can recline to a full lie-flat position.

This provides flexibility for different situations, whether you're travelling by car or using the seat as part of a compatible pushchair travel system.

  1. Convenient 180° rotation

When used with the compatible CYBEX Base S, the Cloud S rotates 180° towards the car door. This can make getting your baby in and out of the car easier.

  1. Comfort-focused details

The Cloud S includes all-round air ventilation with moisture regulation, an XXL sun canopy with a mesh window and refined detailing, including leather-look accents and mesh fabric.

It is also airplane certified, making it an option to consider for families planning to travel by air. Always check airline requirements before travelling.

Getting to know the CYBEX Cloud T

The CYBEX Cloud T i-Size is designed for babies from birth to approximately 24 months. It combines ergonomic positioning with practical features for everyday journeys.

The Cloud T is suitable for babies measuring 45–87cm, with a maximum weight of 13kg.

Ergonomic recline

The Cloud T offers a reclined position in the car when used with a compatible base. Outside the car, it can be placed in an ergonomic lie-flat position when attached to a compatible pushchair.

Ventilation for added comfort

All-round air ventilation helps support airflow around your baby. The Cloud T Plus fabric version also features 3D mesh inserts designed to improve breathability.

180° rotation for easier access

When used with a compatible CYBEX base, the Cloud T rotates towards the car door to make everyday loading and unloading more convenient.

L.S.P. System

The Cloud T features the Linear Side-impact Protection (L.S.P.) System, designed to reduce impact forces by up to 25%. The system can be folded away when space is limited.

This is the Cloud T's stated performance for its own protection system and should not be interpreted as a direct comparison with the Cloud S.

Practical everyday features

Other features include an XXL UPF50+ sun canopy, a 12-position height-adjustable headrest and a removable newborn inlay. According to CYBEX guidance, the newborn inlay should be removed when your baby reaches 61cm, approximately three months old.

The Cloud T can be installed using a compatible base or the vehicle's three-point seat belt, subject to the vehicle and installation requirements.
