Key Difference: Comfort

The main difference between the Britax Graphene and Graphene+ car seats lies in the comfort features they offer:


  • Memory Foam: The Graphene+ car seat includes memory foam for added comfort. Memory foam is the key feature of all Britax “+” models which also includes the Millenia+, b-first ifix+, and b-first ClickTight+.


  • No Memory Foam: The standard Graphene car seat does not come with memory foam.

Why Choose Memory Foam?

Memory foam can be a valuable addition to a car seat for several reasons:

  1. Enhanced Comfort: Memory foam conforms to the shape of the child’s body, providing customized support and reducing pressure points. This can make the car seat more comfortable for the child, especially during long rides.
  2. Improved Body Support: The adaptive nature of memory foam may help distribute the child’s weight evenly across the seat.
  3. Temperature Regulation: Some memory foam materials are designed to regulate temperature, ensuring that the child stays cool in hot weather and warm in cold conditions. It can, however, sometimes have the opposite effect.
