Concord Ultimax i-Size review
This child car seat and Isofix base has passed the regulatory tests required by ECE R129 to be sold as suitable for children from 40cm to 105cm. However, our crash tests found weaknesses in frontal-impact safety. The car seat shell broke during frontal impact crash tests when used forward-facing and the injury risk to a child is high. In side-impact crash tests, the crash test dummy’s head was not protected well enough and hit the side of the car.

It's approved to the latest i-Size R129 car seat rules, has a handy recline feature, side-impact protection and soft padding, but it's not cheap. We've made it a Don't Buy baby car seat in our review because the seat shell broke when we crash-tested it forward-facing. Read our safety alert for more information.
