The car seat then goes onto a Group 2/3 seat giving you a total of four seats in one! Accommodating your child from birth until approx. 12 years old, the Every Stage FX car seat will be a familiar travel companion throughout your child’s childhood. With Guard Surround Safety panels this seat provides extra side protection which can be individually activated for extra room in your vehicle. The 5 point harness and padded headrest adjust simultaneously with the use of just one hand and the autoadjust side wings widen as headrest is raised, eradicating the need for tricky rethreading every few months. Finally, the integrated compartments store the 5 point harness when used as a group 2 booster.
