Cosatto Statement On The All In All Ultra Car Seat Which? Review

Here at Cosatto, safety is our number one priority. All products are designed in-house and one of our founding principles has always been to test all our products to the highest possible safety standards. We work with independent test houses to ensure that each product that we release goes above and beyond the standards of each country where it goes to market.

We are proud to be associated with both ADAC and Which? and are keen advocates of the extensive work carried out by them as well as supporting their upmost dedication to continually improving child safety.


When European Testing Foundation ADAC published their results in October 2024, we were pleased that they were commensurate with our own, because we recognise that such tests far exceed legal requirements. Having our All In All Ultra 360 Rotate i-Size included in their list of recommended models reinforces our commitment to remain a market leading manufacturer of child restraint systems.

We understand that Which? utilises the data from the ADAC crash performance testing alongside its own usability tests and gives its own unique score rating.

Whilst we may not concur with the conclusions of Which?, we value their feedback and have already incorporated their observations into our established process of continual product improvement.


We remain confident in the safety of the All In All Ultra 360 Rotate i-Size car seat.
