Best Car Seat for Taking on Holiday Abroad (UK, 2026): 7 Compared
Last updated 24 October 2026. Prices and ratings taken from Amazon UK listings that day.
The best car seat for taking on holiday abroad depends on your child’s height and weight, because the seven travel-friendly seats we compared on Amazon UK on 24 October 2026 split into two groups. For older children, the BubbleBum inflatable booster is the lightest at a listed 500g (£36.99), and the My Babiie MBCSB10 is the lowest-priced at £15.99. For toddlers, the Maxi-Cosi Nomad Plus2 is the lightest foldable harness seat at a listed 4.26kg (£159.95). Prices ran from £15.99 to £159.95. Follow the maker’s instructions, and check the official guidance for your destination on child seat rules. Our method is below.
Best car seat for holiday abroad: our pick by child’s height
- Toddler (listed from 76cm): the lightest foldable harness seat here is the Maxi-Cosi Nomad Plus2 (£159.95, 4.3 from 958 ratings, 4.26kg listed, 9 to 18kg). A cheaper foldable option is the My Babiie MBCS80 (£69.99, 4.6 from 165 ratings, 8kg listed), and the Cosatto On The Go (£129.95, 5.7kg listed) has only 17 ratings.
- Older child, hand luggage: the BubbleBum inflatable booster (£36.99, 4.3 from 4,854 ratings, 500g listed), whose listing says it is approved as cabin baggage.
- Older child, lowest price: the My Babiie MBCSB10 (£15.99, 4.7 from 1,004 ratings) or the Graco Booster Basic (£17.99, 4.8 from 455 ratings). Both are backless boosters, listed from 125cm and 135cm.
- Older child, foldable high-back: the Cosatto Ninja i-Go (£69.95, 4.8 from 14 ratings, 4.1kg listed), whose page says it is not approved for use as a child seat during flights.
These are picks by listed weight and price, not safety recommendations.

What to check before you choose a travel car seat
A car seat is a safety product, so follow each maker’s instructions, and use the listings below only as a starting point. Four checks matter before you travel:
- Your child’s height and weight: the listings give ranges in centimetres and kilograms. Check your child fits the range for the seat you choose. The Maxi-Cosi Nomad Plus2 lists 76 to 105cm and 9 to 18kg, the My Babiie MBCS80 lists 76 to 150cm, and the booster-only models list minimums of 100cm (Ninja i-Go), 125cm (MBCSB10) or 135cm (Graco), and the BubbleBum lists 15 to 36kg.
- The approval standard: the listings name different standards, such as R129 or i-Size, or in the BubbleBum’s case R44/04. Check the approval label on the seat you receive and what your destination and hire companies require.
- How it fits the car: some seats use ISOFIX and a top tether (My Babiie MBCS80, Cosatto On The Go) and others use the seat belt, such as the Maxi-Cosi Nomad Plus2 and the backless boosters. A hire car may not have the same fittings.
- Flights and luggage: the listings give weights and dimensions, but only some say how small the seat packs down. The BubbleBum listing says it is approved as cabin baggage, and the Cosatto Ninja i-Go and On The Go pages describe airline cabin compatibility, but check your airline’s rules for car seats and hand luggage. The Ninja i-Go page also says it is not approved for use as a child seat during flights.

Its A+ content gives conflicting age ranges, so check the maker’s instructions. It lists 8kg and 42 x 46 x 55cm. The listing does not say how small it folds or give a carry bag, so check with the maker.

How we chose these seats
We searched Amazon UK for lightweight, foldable and portable car seats and boosters and picked seven that cover backless boosters, an inflatable booster, foldable boosters and foldable harness seats across a range of prices and brands. We took prices, ratings, child ranges, weights and features from the Amazon UK listings on 24 October 2026, and the figures here are the listings’ own claims, including any safety or approval claims. We have not checked any approval or certification claims ourselves, so check the label on the seat you receive. Ratings are shown with their sample size. Four of the seven have more than 400 ratings, so treat the Cosatto scores (14 and 17 ratings) as early signals. We left out seats not described as lightweight, foldable or portable, and seats with very few ratings or unclear listings. Prices change often, so use the links to see the current price.
Car seat for holiday abroad: FAQs
What is the best car seat to take on holiday abroad?
It depends on your child’s height and weight. For an older child, the My Babiie MBCSB10 (£15.99) and Graco Booster Basic (£17.99) are low-priced backless boosters, and the BubbleBum (£36.99) is listed at 500g and deflates flat. For toddlers, the listings include the Maxi-Cosi Nomad Plus2 (£159.95) and the Cosatto On The Go (£129.95).
Can you take a car seat on a plane?
Check your airline’s rules. The BubbleBum, Cosatto Ninja i-Go and Cosatto On The Go listings describe cabin-baggage or airline compatibility, and the Maxi-Cosi Nomad Plus2 listing describes a travel bag. The Ninja i-Go page also says it is not approved for use as a child seat during flights. The other listings do not say what airlines allow.
