Comfort and flexibility for every family

Comfort is a key factor to consider when buying a car seat for your child. A comfortable car seat keeps your child relaxed and safe during the journey, which can make all the difference on a long car journey.

The Britax Advansafix IV R has soft, comfortable padding, an adjustable headrest to support your child's head during naps in the car, and an adjustable seatbelt support to keep the seatbelt in place without getting in your child's way. The seat features the EasyRecline system, which makes it easy to vary the seat's inclination, even when the child is in the car and the top tether strap is in place. It offers three recline positions that can be easily changed if necessary.

The Advansafix Flip & Grow system makes it easy to convert a Group 1 car seat into a Group 2/3 booster seat by automatically positioning the SecureGuard and storing the 5-point harness in the seat back. In this way, the seat can be used as a car booster seat for older children. Although this is an undeniable advantage, it can be difficult to appreciate at the time of purchase for some parents who are familiar with the difficulties of converting a group 1 2 3 car seat, such as removing the straps, freeing the headrest and not losing any parts so that the seat can be reassembled later.

With the Advansafix, the cover can be easily removed, the straps can be stored in special slots, and the central strap with the harness buckle can be turned around to become a SecureGuard guide for the seatbelt. The only obvious disadvantage of the Advansafix is its price, which unfortunately increases with each new feature added.

Advanced security features for everyday use

The Britax Römer Advansafix IV R has a 5-point safety harness that offers optimum protection for children between 9 kg and 18 kg (Group 1). In the event of an impact, the harness distributes the forces between the child's shoulders and waist, minimising the risk of injury. What's more, for children between 15 kg and 36 kg (Group 2/3), the harness can be stored inside the backrest to allow use of the vehicle's 3-point seatbelt.

Your child's safety is our top priority. The SecureGuard keeps the lap belt in the optimum position to reduce the risk of injury in the event of an accident. The adjustable SICT side protection system and V-shaped headrest provide excellent protection against side impact. The car seat has also been tested by the ADAC, which gave it a "Good" rating of 2.3.
