Prince lion heart seat protectors awful, too big and not flexible.
I would suggest confirming what stroller you will use then you can determine first seat.
We bought a bugaboo bee pus which only works with a few seats. We chose the maxi cosi mico with two bases. One in each car. Now that she is older we have the recaro pros portion the m3 and the proride in the q5. Proride is almost too tall for rear facing in the m3. No leg room either. But both are perfect for forward facing.
