The Britax Decathlon can accommodate children rear-facing from 5 to 33 pounds or forward-facing from 1 year old and 20 to 65 pounds. Its five point harness system features a push-button one-pull front harness adjuster to easily and quickly secure your child. The infant positioning system helps protect newborns in the Decathlon as they grow and the removable head pillow for toddlers keeps them safe and comfortable when they're older. This and other features like the included belly pad and the tangle-free five-point harness make the Decathlon especially comfortable and convenient.
