Avionaut pixel pro is a fantastically rated seat but it is outside of some people's budget. I really like the Britax babysafe core which is also highly recommended. They both fit on universal/maxi cosi adapters which I assume is what you have with the pram?
Maxi cosi pebble pro
We have the cybex cloud T. I really like it, it's a tad heavy but it's tested to the new standard in the EU
We had a Cybex one when we had our Ocarro for our daughter - sorry I can’t remember exactly which model, possible Cloud?
I've got an ickle bubba 360. I would 1000% recommend a 360 rotating one though
I have the cybex cloud t with the Ocarro ☺️
The cybex is great for comfort and safety but is heavy
Maxi Cosi Cabriofox/ pebble would be good budget options Avionaut pixel pro is just a good seat overall but don't know if it goes on your adapters
The avionaut is fantastic and also really light. It fits on our Joie with the maxi cosi type adaptors. I was told in one of the Baby stores that most car seats fit on most pram adaptors.
Cybex Cloud T x
We have the Maxi-Cosi Cabriofix and don’t like it so I would go with another option
Cybex cloud T with swivel base
Just to add, avionaut have come out with a rotational base for their pixel pro car seats
Avionaut Cosmo is highly recommended
