Hi
I have the Cybex Sirona for nearly 1 month, and I have a major problem with it: my son (18 m) doesn't seem to be confortable at all in it. The problem is that his head is not in alignment, completely twisted. I have used (and still using) 2 other car seats (namely Cabriofix and a Baby Confort 0-4y forward facing car seat that we use when we are staying at grandparents) prior the the Sirona, and DS has always been OK, in a straight position. Note that I used the seat in Back position as DS is not too keen about the shield (but he kind of tolerates it).
I have checked and double checked the instructions and videos, I indeed have left 2 fingers between DS's shoulders and head support, I have tried to fit him deeply in the seat, less deeply etc... but to date, I have never seen DS in what should be the expected potation, i.e. with the head laying upright on the head support.
Has anyone having the Cybex Sirona had a similar problem ? and how did you eventually fix it ? I mean, normally, I guess I would change the car seat for an other brand, but considering the price, you will understand that I am quite reluctant... I dont want to post a bad review about the Sirona seat as the problem may be due to a misuse, but this is not the dream car seat that I was expected, and I must say that I am not impressed, and fairly disappointed.
Looking forward to reading some advise.
