🔍 The Key Difference: Forward-Facing vs Rear-Facing Only

The main difference between the two lies in the direction your child can face:

Britax Dualfix M Plus – Rear and Forward Facing

• Allows rear-facing travel from 61 cm up to 105 cm

• Offers the option to switch to forward-facing from 76 cm onwards

• Ideal for parents who want the flexibility to transition their child to forward-facing later on

• Those who have a 3 door car and need to turn the seat forward to get their child in the car

Britax Swingfix M Plus – Rear-Facing Only

• Rear-facing only, from 61 to 105 cm

• Complies with best practice safety guidelines recommending rear-facing travel as long as possible

• Perfect for parents who want to commit to extended rear-facing for enhanced protection

• Rear-facing travel is proven to be significantly safer in a collision, offering better protection for a child’s head, neck, and spine.
