This is such a fantastic idea, that I cant fault it. My son loves his new backpack, and so do I.
It saves any worry with the school run because often my next door neighbour takes her and my child to school, with the boostapack I don't have to buy several booster seats.
We are flying to France in the summer holidays, and I love the fact that we can pop this in hand luggage and have no worries about having a seat in the rental car - all we have to worry about now is the mental French drivers!
The best thing is that because the bag has a hard shell there is no more crush sandwiches in the bag!!
I cant recommend this enough.
