The Britax Safe’N’Sound Tourer is a lightweight booster that is not required to be tethered to an anchor point, but simply sits on the cars’ seat, and the child is secured with the adult seatbelt. It is specifically designed for portability and ease of use, most particularly for situations where it is necessary to quickly and easily pop a booster in the car to pick up an extra child, or where a car has no anchor points in the third row of seats.The Tourer is the tallest untethered booster on the market, and features deep EPS foam lined headrest for improved side impact protection. It also has a built in sash guide which helps to correctly position the seat belt across your child’s chest and shoulder. The Tourer also has the extendable Secureguard Clip to prevent submarining (sliding underneath the seatbelt). Also the rear impact bars provide structural support and protection to the neck in rear impact collisions. The fully machine washable cover is quick and easy to take off and put back on.
