For car seats, while basically all infant carrier are safe in crash tests because they all have the same basic concept, not all are supportive for newborns and especially tiny and premature babies. They can put babies in a chin to chest position which can restrict my their airways. And some seats have really bulky inserts which fit a newborn well but have an awkward transitional stage where they’ve outgrown the inserts but don’t fit properly in the seats. Some of the more supportive ones are Avionaut Pixel/Cosmo; BeSafe Go Beyond; Britax BabySafe; Maxi-Cosi Cabriofix; Cybex Cloud Z. You can sometimes get these seats in bundles.

We briefly had this for my LO when she was 3ish, but found out you can still rear face with the Britax Romer!

We started out with the britax travel set up. Came with a jogger stroller and infant car seat that popped in the stroller. Can be placed in a car with a seat belt and no base if necessary. Its lasted us 4 kids, still looks great. I still use the jogger stroller for my 1 year old. But also I had purchased the britax double stroller since it was all compatible and I had my kids close together. And I have a decent umbrella stroller for tight spaces and easy grab and go. But, the jogger stroller is definitely the most durable, good quality and still glides quiet and smoothly after 7 years.

Highly recommend Britax One4life. They also make a slim version. Was in a head on crash when someone crossed the median on a highway and hit us head on. We’re so lucky we survived and my daughter who was 14months at the time had no injuries. I only use Britax car seats now.. expecting my third and got a Britax infant seat.

Love Britax! We did the infant seats (they fit our strollers) & then switched to the All4One (which I think is being phased out for a different one.) So easy to use - installation, adjustments, day to day use, genuinely dummy proof.

Both my kids sit in their child seat since day 1, no exceptions. We use Britax Romer seats, they are the ones that are used in the actual crash tests.

Meillä ollut britaxin istuin, kaksi lasta viihtynyt siinä hyvin. On kyllä aika iso ja raskas vehje. Oli hetken aikaa myös motonetistä hommattu joku Cybexin malli, mutta siinä ei lapset tuntuneet viihtyvän. Se lähti sitten kiertoon ja pienemmälle tuli tuo vanha britax kun isompi muksu tarvitsi isomman istuimen. Tosiaan, käykää liikkeissä koeistuttamassa lasta noihin, ja lukekaa noita autoliiton testejä niin hyvä tulee. Monissa paikoissa myyjät ei kuitenkaan mitään tiedä niin kannattaa pari minuuttia perehtyä tuohon asiaan.
