AdvansaFix IV R (Fire Red) by Britax Romer is a multi-functional forward-facing ISOFIX car seat which offers in-car safety and comfort for your little one as it grows with them. Suitable from 9 months to approximately 12 years and is available for you to buy instore or online from Babythingz.

The Britax AdvansaFix IV R Car Seat has been developed to provide maximum flexibility and protection for your child. With its FLIP&GROW function, you can switch from the integrated 5-point safety harness to your car’s 3-point seat belt once your child has reached 15kg and up to a maximum of 18kg - it can be converted back at any time. Extra soft padding and EasyRecline, with its three recline positions, ensure that your little one will always be comfortable. In the event of an impact, its patented Pivot Link ISOFIX System directs the force first downward into the vehicle`s seat, and then forward, more gently – greatly reducing the risk of head and neck injury for your child.

FLIP&GROW - When your child reaches 15 kg (up to a maximum of 18 kg), you must change the integrated 5-point harness to your car’s 3-point seat belt to secure your child in the seat. Simply adjust the headrest and stow the harness in the backrest so it does not get lost. Then, switch the FLIP&GROW adjustment plate so the SecureGuard is above the seat and you are ready to go.

EasyRecline - Suitable for all ages and allows you to adjust the seat into three comfortable positions, even with your child in the seat and without having to re-adjust the top.

5-Point Harness - A 5-point harness is the safest way to secure your child because it keeps him/her tight in the seat’s protective shell. In a collision, the harness distributes the forces of impact across 5 points: two at the shoulders, two at the hips and one where the harness buckles between the legs - protecting from all directions.

Soft Neoprene Performance Chest Pads - These chest pads fit comfortably on your child’s chest and help reduce your child’s movement. In a collision they add greater comfort to the 5-point harness and can be easily removed for washing without disturbing the harness.

SecureGuard - This helps protect the delicate abdominal area by adding an extra (4th) contact point to the 3-point seat belt. By keeping the lap belt in an optimal position over a child’s pelvic bones SecureGuard helps reduce abdominal forces during a frontal collision by up to 35%* whilst allowing freedom of movement during the journey.

Advanced Side Impact Protection (SICT) - This offers superior protection to your child in a side collision. It reduces impact forces by minimising the distance between the car and the car seat and deforms to absorb the energy before it reaches your little one. To benefit from this protection, simply adjust the SICT on the side of the car seat closest to the door.

Highback Booster Protection - This protects in 3 ways: the seat shell provides head-to-hip protection, especially in a side impact; the upper and lower belt guides provide correct positioning of the seat belt; and the padded headrest provides safety and comfort for their head and neck.

V-shaped Headrest - Designed to control the movement of your child’s head, the V-shaped headrest ensures optimal protection during a side collision whilst providing comfort. The headrest and harness can easily be adjusted from the front of the seat to suit your child’s height.

Top Tether - The V-shaped top tether prevents the seat from rotating and reduces forward movement during a collision. Due to its twin anchorage points, it offers greater stability and security than a seat with conventional tethers.

Quick-Remove Cover - Things can get pretty messy on the road - drinks get spilt and children can get car sick. The machine washable seat cover is easily taken off without removing the harness, so you can clean up quickly and get on your way.
