My 2 1/2 year old grand-daughter was in a recent tragic car accident with her mother. Her mother did not survive but my grand-daughter only had minor injuries. She was in the Britax-roundabout. The ER doctor told us that the side protection and the sturdiness of her car seat helped saved her. I will never put my grand-children into any other brand except a britax!

I like britax products and their quality, however, I'm disappointed with this seat. Though is says it can rear face up to 40lbs my 25lb 32in daughter is already feeling the squeeze. Compared to my other seat (chicco) it seems shorter in the leg room area. Also, no matter how much we tighten the install feels loose to me even with the latch system. Our britax infant bucket was nice and snug, but this installs loose. I also have issues tightening the straps, I try to follow the "pinch test" so that she's nice and snug but I pull really hard and she still feels loose in it, I've rethreaded it in hopes to correct it to no avail. My baby is on the lean side but she's not tiny at all. Anyway, I'm sad to say we weren't happy with this and will get a second chicco nextfit instead.

    Needed a second car seat for baby as we both drive kiddo around a lot and forget to switch. The anchors on each side make installation a breeze and each side secures down tight with its own pull strap. Only had the seat under a month and haven't noticed anything wrong....

    Nice car seat, unhappy with material & delivery

    Comments about Britax Child Safety 1011449 1011449 Britax Roundabout (G4.1) Convertible Car Seat - Onyx:

    I personally have this exact car seat, and I like it although the material keeps coming apart. I've had a replacement cover sent and that one is having the same issue. I was a little unhappy that this particular order (that was purchased for a friend) came in a box that had looked like giants played soccer with it. There was an attempt to re-tape the damaged areas, but I don't think I would be comfortable putting my child in a car seat that arrived in that condition (aren't you supposed to throw away a car seat that had been in an accident??).

      Best car seat I've ever purchased

      By AprilA

      from Wyoming, United States

      Comments about Britax Child Safety 1011449 1011449 Britax Roundabout (G4.1) Convertible Car Seat - Onyx:

      I purchased the Britax Roundabout for my son when he was about 8 months old. He turned three last month, and we're still using it. I love it just as much today as I did when I purchased it. Every couple of months I take the cover off and wash it, and it looks brand new. The seat is extremely easy to install/uninstall in the car, and is much more comfortable than most seats. It's also very easy to buckle my son into.

      Comments about Britax Child Safety 1011449 1011449 Britax Roundabout (G4.1) Convertible Car Seat - Onyx:

      I really like Britax products and we had the Bsafe infant carrier. When we transitioned our infant to the Roundabout we were disappointed with the harness. We struggle on a daily basis to get the harness snug enough. We like the design and fit. It seems like a really safe carseat, but struggling to get the harness snug is a big disappointment. I want to make sure my child is safe.

        I use this car seat for taking my son to preschool in the morning, but we have a larger, more advanced car seat in my wife's car for road trips. I like the quality of the padding in the seat, but the shoulder straps and tightening mechanism feel a little chintzy (but still safe).
