I initially chose the Britax B-Safe 35 Infant Car Seat based on research on car forums. After a week of use, we ended up replacing it with the Cybex Aton, which was slightly smaller and lighter, to better fit into our small car.
This car seat worked well for our purposes, but this version has a limited canopy that provides minimal sun protection, and the material was not very comfortable for the baby, although I think it is more comfortable than many other car seats.
FYI, Meritt did not like either car seat.
If I had the choice again, I would try one of the Maxi-Cosi car seats because the material felt more comfortable.
