The Britax Duo Plus is a Group 1 forward-facing car seat which is designed for children from 9kg to 18kg (around one to four-years old). It can be secured using Isofix, the car's seatbelt or a top tether (if your car has one). It's been in Britax's range for a while, and won a variety of awards over the years. But unlike some others, we crash test all car seats we review. Read the results of this Britax car seat to find out more.
