I think this is a GREAT idea and I'm SO buying one!

I've been through the booster seat phase twice with my eldest two and my youngest is getting to that age where a booster seat is all he needs now.

He's not in my car all the time and I'm not one for having a lot of kid paraphernalia hanging around in it; having car seats and booster seats rattling around in my boot drives me insane.

So HOW fantastic to have an inflatable booster seat instead; blow it up when you need it, deflate it when you don't and bung it in the glove box or a door pocket; absolute genius in my opinion.

It would also be ideal for the grandparents to keep, just in case they ever need to collect your child from school (or wherever) and your car seat isn't to hand.  OR for taking on holiday and using whenever a higher kiddy vantage point is required.

I'm rather smitten with this inflatable booster seat, can you tell?! And so are others, the reviews are rather grand.

This ISN'T an Amazon 'Deal of the Week' so the price may inflate (or deflate, of course - do you see what I did there?!) depending on how Amazon feel at any given moment; I'm grabbing one now.

Happy inflatable boosting!

A quick look-see around Internet land would suggest that John Lewis has these Trunki BoostApak travel booster seats on sale for the same price BUT you will pay for delivery, unless you can go and collect it from the store; the remaining usual suspects are all selling them for the full retail price.

A Trunki BoostApak travel booster seat before is an interesting combination of a booster seat and a backpack and rather ingenious, I think.

The law requires all children under 12 years old, or 135cm in height, to use a booster seat - my oldest two were mortified when this law came in and were most relieved when they were over the height limit!

We all know this particular law makes good car safety sense - not like the 'cram as many kids as you can in the back of the car' ways of my childhood - but it does mean you can be caught short without a booster seat if the unexpected happens; a  Trunki BoostApak is a nice solution.

Suitable for children aged between 4 and 12 years old, it's a hand-luggage approved rucksack which doubles as a booster seat and is very handy for car-sharing and and taking on family holidays.

If you're going to be out an about travelling by train or bus it will allow your child to be high enough to look out of the windows and if you need to grab a cab then you'll still be able to comply with car safety law.

The Trunki BoostApak has fold-out seat belt guides, hi-visibility horns and reflective trim and the cover is removable cover for cleaning.
