The Trunki BoostApak can go everywhere you go, taking the hassle out of travelling with your child's booster seat whether you are car pooling or travelling abroad. When you need to take the seat out of the car, BoostApak can be worn as a hand luggage-approved backpack, with 8 litres storage capacity for your travel bits and bobs. It's lightweight enough for a child to carry, and the hard plastic shell protects contents from getting squashed when in use.
