Summary
Birth to 12 Years in One Seat — Cosatto All in All Ultra 360 Rotate i-Size
From the first drive home to the school run at age 12, the Cosatto All in All Ultra 360 Rotate i-Size is the only car seat you'll ever need. Engineered for safety, designed for real life, and finished in the beautifully understated Whisper colourway.
Effortless 360° Rotation
A smooth one-hand mechanism rotates the seat a full 360°, so you can place or lift your child at the car door — no awkward bending, no stretching. The integrated rebound bar adds an extra layer of collision protection, and the seat locks securely into rearward or forward-facing with a satisfying click.
Grows With Your Child — Birth to 150cm
Starting from birth (40cm) all the way to approximately 12 years old (150cm), the All in All Ultra transitions through every stage: infant, rearward-facing, forward-facing, and booster. The rotating mechanism works at every height, so older children can climb in and out independently.
i-Size Safety — Tested Beyond the Standard
Certified to the latest R129/03 regulation, this seat undergoes mandatory side-impact and rollover testing using the most current crash dummies. Cosatto tests beyond standard R129 speed requirements, in line with ADAC levels — one of the most rigorous independent testing programmes in Europe.
- Premium pop-out SIPS (Side Impact Protection System)
- Deep side-wings with energy-absorbing foam inserts
- Cosatto exclusive 5-point anti-escape harness system
- Anti-slip, energy-absorbing tummy and chest protectors
Comfort That Keeps Up
Four recline positions in both rearward and forward-facing modes. A one-handed harness and headrest adjust simultaneously — no rethreading required. Magnetic harness holders keep straps out of the way while you settle your child, and a colour-coded buckle indicator confirms a secure lock every time. An extendable hood provides shade on sunny journeys, and plush padded liners are fully removable and machine washable.
