Cosatto All in All Ultra 360 Rotate i-Size Car Seat – Whisper

Finding one car seat that genuinely supports your child from infancy through the school years can make family life significantly easier. Instead of replacing seats every few years, parents can invest in a solution that evolves alongside their growing child while maintaining the highest standards of comfort and safety.

The Cosatto All in All Ultra 360 Rotate i-Size Car Seat – Whisper has been thoughtfully engineered to do exactly that. Suitable from birth to approximately 12 years (40–150 cm), this premium all-stage car seat combines cutting-edge safety technology with intelligent everyday convenience and luxurious comfort.

Its seamless 360-degree rotation, integrated ISOFIX base, extended rear-facing capability, and elegant Whisper finish create a car seat that feels every bit as premium as it performs. Whether you’re bringing your newborn home for the first time or driving your older child to school, the All in All Ultra is designed to protect every journey.

One Car Seat for Every Stage of Childhood

Children grow rapidly during their first twelve years, and their travel needs change just as quickly.

Rather than purchasing multiple car seats as your child develops, the Cosatto All in All Ultra adapts effortlessly through every stage.

Beginning as a rear-facing infant seat from 40 cm, it gradually transitions into a forward-facing seat before finally converting into a high-back booster suitable up to 150 cm, approximately 12 years of age.

This intelligent versatility provides exceptional long-term value while ensuring your child remains protected with age-appropriate support throughout every milestone.

Smooth 360° Rotation for Everyday Convenience

One of the standout features of the All in All Ultra is its effortless 360-degree rotating seat.

Using a simple one-handed mechanism, parents can rotate the seat towards the vehicle door, making it significantly easier to lift newborns into position or help older children climb in independently.

No more awkward stretching, twisting, or leaning into the vehicle.

The integrated rebound bar not only contributes to the smooth rotation but also enhances safety during a collision while creating additional legroom for growing children.

Unlike many rotating seats, the All in All Ultra continues rotating throughout its entire lifespan, making everyday use remarkably convenient even as your child gets older.

Advanced Safety Without Compromise

Safety is the foundation of every Cosatto car seat.

The All in All Ultra has been developed to meet the latest R129 i-Size regulations, including mandatory side-impact and rollover testing using the newest generation crash-test dummies.

It has also been tested beyond the minimum R129 requirements, following ADAC-level testing principles for enhanced confidence.

The seat incorporates Cosatto’s premium Pop-Out Side Impact Protection System (SIPS), helping absorb collision forces away from your child’s head and neck during a side-impact accident.

Deep side wings, energy-absorbing foam inserts, and a reinforced protective shell work together to create a secure environment for every journey.

Extended Rear-Facing Protection

Experts recommend keeping children rear-facing for as long as possible because it offers superior protection during frontal impacts.

The All in All Ultra supports extended rear-facing travel up to 105 cm, allowing your child to remain in the safest possible position well beyond infancy.

As they grow, the seat smoothly transitions into forward-facing mode before eventually converting into a high-back booster.

Every stage has been carefully engineered to provide appropriate support while maintaining maximum safety.

Cosatto’s Exclusive 5 Point Plus Anti-Escape System

Young children naturally become curious and active during travel.

To help prevent little passengers from slipping their arms out of the harness, Cosatto has developed its patented 5 Point Plus Anti-Escape System.

Available during the harness stage (76–105 cm), this exclusive feature provides parents with additional reassurance that their child remains securely positioned throughout every journey.

Combined with anti-slip chest and tummy protectors, the system improves both comfort and overall restraint performance.

Premium Comfort for Growing Families

Long journeys become considerably more enjoyable when children travel comfortably.

The All in All Ultra features a multi-stage newborn insert that provides tailored support from 40 cm to 87 cm, ensuring smaller babies remain correctly positioned during their earliest months.

As your child grows, the inserts can gradually be removed to create additional space while maintaining ergonomic comfort.

An extendable hood offers valuable shade during sunny journeys, helping create a calm and comfortable environment for sleeping babies.

Four recline positions are available in both rear-facing and forward-facing modes, allowing children to relax comfortably whether awake or asleep.

Intelligent Adjustability

Children’s growth never follows a schedule, which is why the All in All Ultra has been designed for effortless adjustments.

Its 11-position adjustable headrest works together with the non-rethread safety harness, allowing parents to change both simultaneously using one hand.

This intelligent system eliminates complicated strap adjustments while ensuring the harness always remains correctly positioned.

When your child becomes ready for booster mode, the harness stores neatly within the seat itself, eliminating the need for separate storage.

Eco-Friendly Materials

The Whisper edition demonstrates Cosatto’s commitment to sustainability.

Its soft premium fabrics are produced using recycled plastic bottles, reducing environmental impact without compromising comfort or durability.

The plush covers are fully removable and machine washable, helping parents maintain a fresh, hygienic seating environment despite everyday spills and messes.

Simple ISOFIX Installation

Installing the All in All Ultra is quick and reassuring.

The integrated ISOFIX base with support leg provides secure vehicle installation while clear quad green installation indicators confirm when the seat has been fitted correctly.

This reduces installation uncertainty while helping parents travel with complete confidence.
