Integrated child seats and side support – does anyone have experience / photos?

Hello, two years ago I had the integrated child seats swarmed up. Only when my child was sitting on it did I find that it has no side stop on it, especially when it falls asleep and the head inevitably falls to the side. In the bad passat there is a really good solution for this case: a kind of headrest with shoulder guide, which is placed on the top of the backrest. However, with Volvo, the often famous pioneers in terms of safety, one seeks such an aesthetically appealing and seemingly safe solution in vain. Instead, a padded cover and headrest in bright blue with dots is recommended, the whole should be pushed over the integrated child seat. So far I have spared the expenses for this ugly part, but meanwhile the child finally grows out of its Roman seat, especially his legs hardly fit into the footroom behind my seat (am even 1.97 m tall) – the integrated seats could not help here. So what do? Has someone experience with the reference available as original accessories plus. Headrest and perhaps also a photo of the whole thing in his V70?
