ebp913:I'm really really glad that your baby is okay but this still doesn't mean that Britax makes the "best" or "safest" car seats. Just want to clarify that. All car seats go through the same safety tests.
This is only partially true. All carseats go through the same minimum safety tests. Many companies, Britax being one, go above and beyond in their own research and testing to increase the safety of their seats.
OP - I'm thrilled your LO is okay! We have a Britax Blvd and love the seat and would also highly recommend it. Also, kudos to you for having LO strapped in properly and having the seat properly installed! It's such an important thing to double check!
