What is the difference between this new version and the seat before?

Compared to its predecessor, this seat has been upgraded with 3 new features:
1. The Dynamic Force Absorber™ in the headrest takes side impact protection to a new level
2. The additional side impact protection SIP+ is now designed with a slide-on construction for quickly and securely attaching it to the seat
3. The Ergo-Move Shoulder Pads™ are developed based on insights from the back-development experts AGR and give the child added movement space for the arms
