Full product information

Britax Romer Advansafix IV R

Discover the seat that does it all, taking your family right the way through from 9 months up to 12 years! An updated version of the popular forward facing seat from Britax Romer, the ADVANSAFIX IV R provides maximum flexibility and protection thanks to its advanced safety features. 


Grows with Your Child

ADVANSAFIX IV R is the only seat you'll ever need! Developed for children from 9 to 36 kg, the whole family can travel in safety and comfort from 9 months right the way through to 12 years thanks to the easy FLIP&GROW function. Switch from the integrated 5-point harness once your child reaches 18 kg to the 3-point seat belt, with nothing to remove and therefore nothing to lose should you want to convert back at any time. The adjustable headrest, extra soft padding and three-position recline ensure that your family are comfortable on every journey.

Extra Safe

Worried that transitioning from the 5-point harness to the 3-point seat belt is less safe? The ADVANSAFIX IV R is fitted with SecureGuard which holds lap belts in the optimal position over the pelvis, reducing the risk of abdominal injuries during collision. In addition, Side-Impact protection and V-shaped headrest provide stability and shock-absorption in the event of an accident, while the Pivot Link ISOFIX System directs force downwards into the seat and then gently forward, greatly reducing the risk of head and neck injuries. 


The V-shaped top tether prevents the seat from rotating and reduces forward movement. thanks to duel anchorage points, the ADVANSAFIX IV R offers greater stability and security while unique pattern stitches are designed to progressively rip in a controlled fashion, absorbing front-impact force.

The high-back booster performs 3 safety functions: The shell protects from hip to head, especially in the event of a side-impact collision, the upper and lower belt guides provide the best positioning for the seat belt, and the padded headrest protects your child's head and neck throughout every growth spurt. 


Additional Features:

  • Quick-remove, machine washable cover for all types of spill
  • ISOFIX indicators ensure seat is fitted correctly
  • One-handed headrest and harness adjustment
  • 2 year guarantee
