Choosing your baby’s first car seat is one of the most important safety decisions you will make as a parent. For many families shopping at Chelsea Baby, the search quickly narrows to one name: Cybex Platinum. At the centre of that conversation sits the Cybex Cloud T i-Size — an infant car seat that has become a benchmark for safety, innovation, and ergonomic design.
This is not simply a carrier to get your baby from A to B. The Cloud T i-Size is designed to support a baby’s body from the very first journey home, through daily life, travel, and the early months of development — all while delivering some of the strongest independent safety test results available today.
In this in-depth review, we explore why the Cybex Cloud T i-Size is regarded as one of the finest infant car seats on the market, how it compares to conventional infant carriers, and whether it is the right choice for your family.
Designed Around the Needs of Newborns
From the moment a newborn is placed into a car seat, posture matters. A baby’s spine is still developing, their neck muscles are weak, and prolonged time in a poorly designed seat can place unnecessary strain on their airway and back. The Cybex Cloud T i-Size is engineered with this understanding at its core.
Near-Flat Ergonomic Recline
One of the Cloud T’s most defining features is its ergonomic near-flat recline position when used outside of the car. Unlike traditional infant seats that lock babies into a semi-upright posture, the Cloud T allows: Improved spinal alignment, reduced pressure on the neck & better breathing position during rest. This is especially valuable during longer outings, café stops, or when the seat is used as part of a travel system.
Newborn Inlay for Early Support
For smaller babies, the removable newborn inlay ensures a secure, supportive fit from birth. It gently elevates the baby’s torso and head, creating a safer posture until they grow strong enough to sit more independently. As your baby grows, the inlay can be removed to provide more space without compromising safety.
Advanced Safety Where It Matters Most
Safety is the foundation of every Cybex Platinum product, and the Cloud T i-Size consistently ranks among the top-performing infant car seats in independent crash testing.
The Cloud T meets the latest i-Size (R129) safety standard, which includes: Mandatory side-impact testing, rear-facing travel for infants & height-based sizing for a better fit. This ensures protection not just in frontal collisions, but also in side impacts — one of the most dangerous crash types.
Linear Side-impact Protection (L.S.P.)
The integrated L.S.P. system absorbs impact forces early in a side collision, reducing the amount of energy transferred to the baby. When deployed correctly, it can reduce side-impact forces by up to 25%, adding a crucial layer of protection without complicating daily use.
Energy-Absorbing Shell
The Cloud T’s shell is designed to flex and absorb crash energy, dispersing force away from the baby’s body rather than allowing it to concentrate in one area. Combined with deep side wings, this creates a protective cocoon around your child.
The Base T: A Critical Part of the Experience
While the Cloud T can be installed with a seatbelt, most parents choose to pair it with the Cybex Base T — and for good reason. 180° Rotation for Easy Access, With the Base T, the Cloud T rotates toward the car door, allowing you to place or remove your baby with minimal strain. This is not just a convenience feature; it significantly reduces the risk of Incorrect harnessing, twisting or awkward lifting & back strain for parents
Visual Installation Indicators
Incorrect installation remains one of the biggest safety risks with car seats. The Base T addresses this with:
-
Clear visual indicators
-
Audible confirmation when correctly fitted
This reassurance is invaluable, especially for first-time parents.
Future-Proof Compatibility
The Base T is part of Cybex’s T Line modular system, meaning it can later be reused with the Sirona T i-Size toddler seat — offering better long-term value.
Everyday Practicality for Modern Parents
Luxury design means nothing if a car seat doesn’t work seamlessly in daily life. The Cloud T i-Size excels in the small details parents notice every day.
One-Handed Recline Adjustment - the recline function can be adjusted smoothly with one hand, allowing you to adapt the seat without disturbing your baby.
12-Position Adjustable Headrest - As your baby grows, the integrated headrest and harness system adjusts together, ensuring correct positioning without rethreading straps — a common frustration with cheaper seats.
XXL UPF50+ Sun Canopy - the large sun canopy offers excellent protection from sunlight, wind, and overstimulation, making the Cloud T particularly well suited for urban life and travel.
Premium, Breathable Fabrics - Cybex Platinum fabrics are selected for both comfort and durability. Breathable materials help regulate temperature, reducing overheating — a key concern for infants.
Travel System Ready
For parents on the move, the Cloud T i-Size integrates seamlessly with Cybex pushchairs and many other leading stroller brands using adapters. This allows you to move your sleeping baby without disturbance, create a flexible travel system & reduce the need for bulky carrycots on short trips.
At Chelsea Baby, this makes the Cloud T a popular choice for families building a coordinated travel system from day one.
