Nuna Tres lx review

Product alert

This child car seat has passed the regulatory tests required by ECE R129/i-Size to be sold as suitable for children from 40cm-145cm. But in our own tests, which are conducted at higher speeds and stronger forces than the standard requires, our lab experts spotted issues when testing the frontal impact. Any car seat scoring 45% or less will become a Which? Don't Buy. Log in or sign up to Which? for more details.
