Rank #3 in Best Toddler Car Seats 2026: 10 Ranked, and Where the Specs Disagree
Britax Römer Discovery Plus 2 i-Size Car Seat
Price and rating as shown on Amazon when we collected them. Both change.
The Britax Römer Discovery Plus 2 is a forward-facing high-backed booster listed at £109.00, third in this guide with 4.7 out of 5 from 599 ratings. Britax Römer sells it for children of 100–150 cm, which the bullets translate as 3.5 to 12 years, and it takes ISOFIX or the car's own 3-point belt. The listed weight is 5.9 kg and the listed dimensions are 42 by 44 by 63 cm, which is the sort of width that lets the third bullet claim up to three seats across the back row of many cars.
The listing disagrees with itself in two places, and both are worth reading before you buy. The second bullet reads "Made in Germany - Engineered and build in Germany", while the spec table's Country Of Origin field reads China. And although the size range and the i-Size name are height-based — 100–150 cm — the spec table also carries a Maximum Weight Recommendation of 36 Kilograms and a Forward Facing Maximum Weight of 36 Kilograms, weight figures that a height-based 100–150 cm seat does not otherwise use. For context, the 100–150 cm seats in this guide run from £59.99 to £189.99, so £109.00 sits in the middle of that band rather than at either end.
Everything on this page comes from the Amazon listing for this seat, not from any testing we carried out.
