Britax Römer Adventure Plus 2
From 100 cm, up to 150 cm (~3.5-12 years).
Pros / Cons
Pros
- Adventure Plus 2 is one of the cleaner booster buys if your car does not have ISOFIX, because the whole seat is built around straightforward belt-fit high-back use rather than pretending to solve earlier stages.
- The shell is compact enough to work well in many cars while still feeling more substantial than the very cheapest boosters.
Cons
- It is still a pure booster seat, so this only works once your child is genuinely ready for 100-150 cm use.
- Because it is deliberately simple and belt-fitted, it gives up some of the planted feel and extra features you get from heavier ISOFIX-friendly rivals.

Britax Römer Adventure Plus 2 makes the most sense if you want a proper high-back booster but your real-world use case is simple belt-fit everyday practicality. That is where it earns its place. Britax is not pretending this is a multi-stage seat or a feature-heavy premium model. It is a straightforward high-back booster that is especially sensible in cars without ISOFIX anchor points, and that clarity is part of its appeal.
The limitation is that clarity cuts both ways. Because it is a pure booster, it only makes sense once the 100-150 cm stage is genuinely appropriate. And because it is deliberately simple, it does not have the same planted feel or extra convenience features as heavier ISOFIX-friendly boosters. It is strongest when you want a sensible, compact, known-brand booster that keeps the brief narrow and honest.
