Axkid minikid 4 is a test extended rear facing seat up to 36kg, also Swedish plus tested. We just bought the minikid 2 as well and love it! Not isofix but extremely quick to install and easy to move between cars if needed. Unfortunately extended rear facing and isofix don’t normally go together!
What centiles is baby on? What’s your budget?
Isofix and long lasting don’t really go together cause isofix has a low weight limit, with a handful of exceptions. Best to add your little one’s weight and height so the group can help
Axikid One 2 for us. Could last up to age 7 (we have a tiddler 3yo) so even though it’s expensive we will get the use out of it and it’s safe 👌🏻
I’m going to get the maxi cosy 360 🩷
