Britax Boulevard Convertible Car Seat Onyx

I searched and searched for a car seat when it became apparent the baby seat for my little one was not working for him (He got hot and sweaty and got a rash from it). He needed one that would allow his skin to breath. This seat is great! He sits up high so he can see out the windows, he doesn't get too hot in it, and it is easy to install both with the latch system and the regular seat belt (we transfer from my car to grandma's every morning). If I would have known I would have used this seat from the very beginning! It fits in my car and my mom's just fine (Sportage and Tuscon). Don't mess around with the little baby seats - just get this one! It may seem expensive, but you will not have to buy another one until they are about 5 and ready for a booster.

We were not really able to use it rear facing for our 13 month old daughter in the BMW 325 (E46) - there was no space for her legs between the seat and the rear seat. However, it was just perfect forward facing. She is always quite happy in it - the straps only occasionally get twisted and even then are quite easy to sort out. I like the added stability from the top tethers. Quite happy with this seat

Got two of the Britax Boulevard Convertible car seats; one for my ten months old and one for my three year old. I have used Takata seats in the past so I know that child seats can be bulky but these seats where just massive. Especially when in the rear-facing position. When I drive; the seat is up against my headrest actually forcing me to sit in a more upright position than I would normally do. (And this is in a van.)
In terms of usability I do appreciate the adjustable back harness but the crotch strap is positioned so that the kids end up sitting on it in 90%+ of cases making it a hassle to get the kids seated.

In sum, the safety that this product provides is probably good but I am sure that there are better alternatives out there. For rear-facing I have yet not tried anything else but for forward-facing I would definitely recommend the Graco Nautilus product Graco Nautilus 3-in-1 Car Seat in Matrix, which I have recently switched to for my older kid.

This is a car seat designed especially with kids in mind along with great safety features not found in other car seats. Its so cozy that my daughter likes it so much that some times she doesn't want to be taken out of it. Overall, i'd recommend this product.

My partner and I wondered if we were overspending on this -- twins equals expensive times 2 -- but if you are ever going to blow it out, a child's car seat is the place to do it. As others here mention, this is a *big* seat. It's great in our minivan, but be apprised. We are very happy with the seats.

Regarding customer service: under stressful conditions, I needed to move one of our seats from our newer Odyssey, which has LATCH connectors, to our older Accord, which does not. This lead to some questions about where to install the seat, and whether I was doing it correctly, so I called Britax customer service. This kind of detailed phone support can be hard, and the person I spoke to was bright, articulate, precise, personable, and extremely helpful in ensuring that I was doing this correctly and in spec. So, wow, awesome.
