Hi.
I realize that all seats pass the same safety testing, but what makes Britax so much more expensive? Is it just the clicktight technology that raises the cost?
I had my eye on the 4ever, but my 7 month old looked really uncomfortable, as the head and back part of the seat is not flush resulting in babies head being pushed forward. Just looked like he would get a kink in his neck.
He seems very comfortable in the Grow and Go and the Britax Boulevard. money is no problem, but why pay more for Britax?
Thanks!
