Trunki Boostpak Group 2/3 Car Booster Seat, Black/Green

Product information

With the law requiring all children under 12 years old or 135cm in height to use a booster seat it’s important to have one to hand at all times. Boostpak is the ideal solution, a spacious, hand-luggage approved rucksack which doubles as a booster seat, perfect for car-pooling and family holidays.

The Boostpak eliminates the need to hire a second hand car seat when renting a vehicle on holiday. It also doubles as a dining booster when eating out, and can be used for trips to the cinema.

Featuring a hard plastic shell, fold out seatbelt guides, wipe clean removable cover, ergonomic back padding and ID tag. The Boostpak is certified to regulation ECER44.04 and is suitable for Group 2 and Group 3. It has hi-visibility horns and reflective trim, so your little one can be safely seen when they're using it as a back pack.

Suitable for ages 4-12 years (15-36kg, or up to 135cm)

All our car seats and infant carriers comply with current European regulation ECE R44.04.


  • Under no circumstances should a car seat be used on a passenger seat where there is an airbag.
  • Correct fitting of all car seats and boosters is of paramount importance to make them most effective in the event of an accident. Not all car seats fit all cars and it is important to check for fitting suitability on all cars you intend fitting the seat to, as well as re-checking if you change your car.
  • Always read the instruction booklet which comes with your car seat to achieve a safe and correct fitting, retaining the guide for future reference. We recommend fitting your car seat in advance of first using it.
  • We recommend that babies shouldn`t be left in Group 0/0+ car seats (infant carriers) for prolonged periods.



  • Please make sure that you check the car seat you choose is suitable for your car before ordering.
  • Some of our shops offer a car seat fit test, where a Nursery advisor will test the display model in your car to check that it will fit properly. Please contact your local shop to see if this service is available. Alternatively, please contact the car seat manufacturer who will be able to advise whether their model will be suitable for your car.

Q & As

Rated 4.8 out of 5 by 60 reviewers.
Rated 5 out of 5 by Big hit with my five year old grandson The trunki is ideal for days out and my grandson loves it. I bought it for our trip to Italy later in the year but he has used it on every day trip out with myself and his other grandparents since I bought it. Worth every penny and even keeps all his super heroes in a safe place for the journey. 17 May 2016
Rated 5 out of 5 by Compact and practical Good option for travelling and for avoiding paying unnecessary car seat charges to the rental company. Easy to carry. Not suitable however for long term daily use as seat is not as comfortable as a regular car. Good solution for travelling. 27 April 2016
Rated 5 out of 5 by Really useful product I love it - Neat and tidy and the fact that my son can store toys in it resulting in a tidy car. Really handy when we go shopping as he wants to carry everything 10 November 2015
Rated 4 out of 5 by Very useful I bought this for my granddaughter to use when we went on holiday to Turkey recently. She used it to carry her bits and pieces on the plane and we used it on transfer and taxi rides whilst there. Not sure if we used it correctly though as the instruction diagrams are quite difficult to follow.I think she'll get future use out of it too. 10 November 2015
Rated 5 out of 5 by Brilliant product Great idea, I wish I had known about it ages ago, to save me the hassle of trying to stuff booster seats into already overfilled suitcases! Used only on one holiday so far but product looks durably made and of high quality. Son loves it, plenty of space for snacks and games whilst travelling. He said it was comfortable to sit on, too - and he did had to spend a fair few hours sat, so it must be ok! 02 September 2015
Rated 5 out of 5 by Wish I had known about this sooner! Bought this product to take on holiday. Saved more than the purchase price by not having to hire a car seat from the car hire company. Useful storage compartment when carried as a backpack. Great quality. 01 September 2015
Rated 5 out of 5 by Ideal item for a 3+ child. Bought it online and collected it from Waitrose London. No problems getting it. I bought it for my granddaughter as she was getting too big for the other car seat. The product was light practical and easy to fit. Plus she actually could carry it as her backpack. An excellent idea, plus it says this could be used for up to 10 years of age. 21 July 2015
Rated 4 out of 5 by Great product Our 3 year old loves this seat. Perfect as a second car seat for short journeys, trips to theatre/cinema as booster seat etc. Easy to use and carry. A good buy 17 February 2015
