Full product information

Britax Romer Kidfix 2 S 

The Britax Romer Kidfix 2 S in Cosmos Black is the latest highback booster from Britax, suitable from 4 to 12 years (approx.) with Side Impact Protection, ISOFIX or belted installation and, unlike past models, has the ability to be used without the backrest as a standard booster seat. 



The Britax Kidfix 2 S features a removable backrest to allow you to transition easily from your highback booster to a standard booster seat. Britax recommend using the seat as a highback booster for as long as possible, however have allowed the Kidfix 2 S to be used without the backrest once your child reaches 135 cm in height. When the backrest is fitted it provides a number of safety features, including high side wings and Side Impact Protection that helps to absorb and divert any force of impact away from your child in the event of a collision. The headrest is also ergonomically designed to provide the optimum position for on-the-road naps. 


The Kidfix 2 S is able to be installed into your vehicle using the ISOFIX connectors, your car's 3-point seat belt, or a combination of both for optimum safety. The seat features SecureGuard technology that helps to position the lap belt in the best position over your child's pelvic bones, which reduces the risk of abdominal injury on impact. The belt clip is also designed to hold the seat belt in the best position over the shoulders when used as a standard booster. 


The adjustable headrest allows the Kidfix 2 S to grow with your child over the 8 years of use, and ensures that they are well supported and protected with the headrest sitting at the recommended height of just above their shoulders. The V-shaped back allows for extra support and space as they grow and develop, ensuring your child is completely comfortable throughout the entirety of the seat's use. To help keep your Kidfix 2 S clean over the years, the covers are easily removed and are suitable for machine washing.
