Can you get a replacement polystyrene head support

Good Afternoon

The original Maxi Cosi Priori carseat has been discontinued in the UK for some years and it is no longer recommended for use as in the UK it is at least 5 years old. We recommend that a carseat is replaced once it is 5 years old as the plastics and polystyrenes which make the carseat safe will naturally degrade over time and in the event of an accident it may not provide the protection required. For this reason we are not able to provide spare part items in the UK for this product. If it is a Maxi Cosi Priori SPS, Priori XP or PrioriFix please contact customer services regarding this by going to www.maxi-cosi.com and selecting the country you're in for your message to be sent to the customer service department in your country.
