Hi, thank you so much 😍

Hi! Some movement of the carseat on the base is normal. This serves to prevent, in the event of an accident, the child from suffering damage due to the impact. If the structure remained completely rigid, the impact forces would reach the baby without being distributed throughout the rest of the chair and its energy-absorbing structure. All existing and future CYBEX and GB products comply with current legal regulations and are subject to extensive internal testing. However, if you want to make sure that the movement you mentioned is normal, you can send us a video through our contact form on our website, or approach your retailer to check it. Kind Regards.
