I-BOOST i-Size is a perfect solution for children who have already grown out of a car seat but haven’t yet reached 150 cm in height. This booster car seat is ideal for youngsters between 135–150 cm tall, as it guarantees that the car’s seat belt will pass optimally over the middle of the shoulder and chest. It minimises the risk of injury that could arise due to unexpected road incidents. The I-BOOST i-Size car seat has been tested under the latest R129 i-Size standard, meaning it has passed stringent testing. It's lightweight (it weighs just 2.5 kg), so you can easily move it from car to car. It can be installed in cars with and without ISOFIX.
