We went for a Wow 3 pram but the car seats from cosatto are not recommended so we went for a Joie car seat instead
We also went for a wow 3 pram set with the baby car seat (Everything bundle) - I had a look on Which? and the baby car seat was the same score safety wise etc to maxi cosi. We didn’t go for the all stage bundle as the all stages seat scores really low. Plus, when we were in the shop, the assistant pointed out that all babies are different and it’s not as simple as one seat suits all, so better to wait to see how your baby fits in the next stage seats when they’re actually ready for them.
I went the wow 2 everything bundle. The acorn car seat is fine from Cosatto (rates as well as anything else) but unless you are going for the collaboration Cosatto/Axxkid next stage one then I would look for something else. Axxkid is a Swedish brand and they have extra safety features because Swedish requirements are more strict. The pure Cosatto next stage ones don't rate very well I believe.
I went for the wow continental bundle in silhouette. Absolutely love it, and it’s British made and environmentally sustainable. https://www.cosatto.com/products/wow-continental-everything-bundle-a2-silhouette
If you are UK based i would recommend joining the Facebook group car seat safety UK. They recommend buying prams and seats separately as the ones included in bundles are usually safety tested to a lower standard. We have the maxi cosi cabriofix (this was their recommeneded budget infant carrier) but if the seat wouldn't be needed until 15 months I would recommend waiting and buying closer the time as lots of them have different weight and height limits (which is exceeded quicker if your baby is high percentile) hope this helps abit lovely x
