The Britax Römer KIDFIX III S is an excellently designed high back booster seat for children from around 3.5 to 12 years. This version of the popular KIDFIX series is equipped with a shock-absorbing XP-PAD, longer seating area and lined with premium quality fabrics. The SecureGuard system ensures that the vehicle seat belt is always in optimal position even without the backrest.

Height-adjustable headrest and V-shaped backrest ensure a perfect fit throughout your child’s development.
