Rank #5 in Best Toddler Car Seats 2026: 10 Ranked, and Where the Specs Disagree
Britax Römer Adventure Plus 2 i-Size Car Seat
Price and rating as shown on Amazon when we collected them. Both change.
Fifth in this guide, the Britax Römer Adventure Plus 2 is a forward-facing i-Size seat for the 100–150 cm range, which the listing translates as 3.5 to 12 years. It is £99.00, it is rated 4.7 from 391 ratings, and it installs with the car's three-point seat belt rather than a base or Isofix. At 42 x 44 x 63 cm and 5 kg, it is the sort of seat buyers describe moving between cars rather than leaving in one.
The finding on this listing sits in the origin fields. One bullet reads "Made in Germany - Engineered and build in Germany", while the spec table's Country Of Origin line reads China. The same table also drifts past the headline range: the stated span is 100–150 cm, while Maximum Height Recommendation reads 151 cm and Minimum Height Recommendation reads 101 cm. A centimetre at each end is not a reason to avoid the seat, but it is the pattern this guide exists to show — the marketing copy and the spec table are written separately, and only one of them is a field. Every figure on this page comes from the Amazon listing, not from testing we carried out.
How those 391 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“My son finds this very comfy and happily sleeps away journeys in it. Got this one for its slim fit so a passenger can actually fit in on the seat with it. It's also nice to have an option of colours, fed up of black or black and my son loves blue. All in all a great booster seat that my son will be happy in for a few years to come (hopefully😂).”
Verified purchase“This fits well in the car. Is light to move between cars and easy to install and adjust. The child who sits in it says that it is comfortable to sit in.”
