With my first we had a Cybex Cloud Z and had a lot of problems with head flop which we only really got around by ditching the base. We have a Ford Focus and the seats seem slightly sloped which I think is what was causing the problem.
Looking to buy a new seat for a 2nd baby and wondering which option would be best to avoid the same problem again. It will also need to either fit behind a tall driver or in the front seat with airbag off as DD is currently in a huge ERF seat. Must also be easy to carry into the house
