I’ve got the cybex sirona and love it x
I have an axkid spinkid which is great for my girly as she is on the smaller side but any axkid would be great as they are Swedish plus tested (very safe) x
We have the Axkid Minikid and a Movekid in my husband’s car, the second is a bit more compact. I’ve got the Britax Maxway Plus and the Britax Maxsafe Pro in my car, they’re a bit cheaper than Axkid but all Swedish plus tested. We’ll be keeping our girls rear facing as long as possible. Ours are 25 or 36kg seats as they’re both 99th centile chunks!
I second the Avionaut Sky - my little girl has been in it since birth and she always seems so comfy in it! And I like knowing that it’s going to last her until she’s actually ready for a high back booster when she’s older!
