The All in All+ from Cosatto is here. With ISOFIX fitting options in all modes up to 36kg (approx. 12 years old), the All in All+ comes with a range of new features including extra side impact protection and more modes than ever before. The All in All+ offers Extended Rear Facing (ERF) as it’s scientifically proven to be safer to travel rearward for as long as possible. ERF mode is suitable up to 18kg (approx. 4 years old). This seat means you won’t need to consider any other car seat for your child’s entire car seat journey as it takes them all the way up to 36kg (approx. 12 years old). The All in All + is suitable for a wide variety of cars both rearward-facing up to 18kg (approx. 4 years old) and forward-facing up to 36kg (approx. 12 years old). The All in All+ can fit in most cars whether they have ISOFIX points or not. All in All+ comes with a flip-out side-impact protection system and the exclusive Cosatto 5 point plus Anti-Escape system. Plus, even more padding – adding more in-car safety. An easily adjustable harness and recline-lock indicator are just two new features that have been added to improve the comfort and ease of your All in All+ experience. Plus, with one hand easy-adjust, even more recline options and a smaller design for easier transportation, it has you covered.

The current safety guidelines advise that newborn babies are not left in their car seat for longer than 30 minutes. For babies 2-6 months, no longer than 2 hours. It is also safer to keep your child rear-facing for as long as possible –  a minimum of 15 months but ideally 4 years. A child should never be in their harnessed car seat with a thick winter coat or snowsuit on.

2 reviews for Cosatto All in All+

  • Christie Chapman

    It’s amazing my little girl loves it and fits perfectly

  • Tim Gibbons

    Great seat, high quality and very comfortable.

    But way more impressive was the incredible customer service received from pushchair expert.

    Ordered different seats at first which ended up being too wide to fit two of in the bench seat of my van.

    The patience and assistance shown to me by at least 3 different members of staff in deciding whether to swap them, or keep them for the car and order different seats for the van suggests an underlying company policy rather then getting lucky with a particular member of staff.

    Extremely helpful professional service

    Very very impressed

    Very very refreshing

    Thank you
