Britax Adventure Car Seat - Cosmos Black

Britax Adventure Car Seat - Cosmos Black has been designed to give your child the most comfortable adventure possible. This particular car seat can offer your child a smooth ride, as its back climbs very high - meaning that any passenger enjoying a journey in the Britax Adventure Car Seat can relax, without suffering any compromise on their thoracic support.

Why should I choose the Britax Adventure Car Seat - Cosmos Black? 

The Britax Adventure Car Seat - Cosmos Black is a Group 2-3 car seat, and is suitable for passengers weighing between 15kg to 36kg. This roughly translates as being suitable for passengers aged 4-12; the Britax Adventure Car Seat is therefore a worthwhile investment, due to its potential longevity per passenger.

Due to its intended age group, the chair architects at Britax have ergonomically designed the Adventure Car Seat for an older child. The headrest is adjustable, and the car seat can be modified to reach multiple height positions. The Britax Adventure Car Seat will literally grow with your child (and at the end, you’ll wonder where the time went!), and subsequently, has more ‘mature’ features, such as a pull out snack tray – drinks holder included, of course.

The 3 point harness system correctly sits over your child’s shoulder and pelvis when fastened, and the Britax Adventure Car Seat also offers side impact protection, in the event of an accident. Despite its heavy safety features, the Britax Adventure Car Seat is incredibly lightweight, and transporting it between cars is no issue. The cover for the car seat is also removable and washable, which is especially useful to remember when considering that the snack tray may be used whilst in transit.
