BoostApak is the best way to avoid hire charges when travelling abroad. It's a hand luggage-approved backpack that doubles as a booster seat with plenty of space for toys and games to keep everyone content during long journeys. It's also an ideal solution for sharing lifts and travelling in coaches or taxis. BoostApak is a ECE44.04 approved car seat for group 2 & 3, certified to European Union safety standards, recommended for children under 135cm weighing between 15 and 36 kg (approx. 4–12 years). Booster seats are not only important to ensure that your child is safe and comfortable during a car journey, but UK law requires that ALL children under 12 years old or 135cm in height use a booster seat. So it’s essential to always have one with you when travelling by car or taxi.
