    Own 2 Frontiers and the Nautilus, May 19, 2009
    P. moore “P” (Mesa, Az) –

    I own 2 Britax Frontiers in Pink, and the Graco Nautilus in pink as well. As a Mother who owns both models, I will tell you the major differences between these two seats from my point of view.
    #1 Frontier is more expensive (which is why I got the Nautilus for my spare)
    #2 Frontier is SO much easier to adjust the shoulder height strap. With a simple squeeze of a lever, the straps go up. The Graco needs to be rethreaded. This is BIG pain when you have another child who wants to use the seat. With the Frontier, it is no biggie to pull the lever.
    #3 Frontier seat material is prone to wear where the child’s bottom and legs rub on the seat. It also shows WAY more stains and soaks up spills quicker than the Graco.
    #4 Frontier has 3 crotch strap adjustments for easy fitting. The Graco only has 2 which makes the older kids sit on the strap. This can get uncomfortable. My oldest DD takes the pad off of the crotch strap on the Frontier (she says it makes the seat look like a “baby seat” with the pad), but she can not do this with the Graco, as the crotch strap rubs on her legs causing red irritation when wearing shorts. The graco pad is very thick and wraps the entire strap (between the legs) and then goes up to sit on the belly. She does not seem to mind sitting on it, but it does not look too comfortable to me.
    #5 Padding on Frontier is WAY thicker (on both seat and seat back)and more comfortable to sit on. I can’t imagine that the Graco would be comfortable for long trips.
    #6 Heads slump forward for younger kids when sleeping in the Graco. The “wings” around the head are very fat (giving the appearance of a “yonger child’s seat”) and are so close to the child’s head that it causes it to go forward when sleeping. The frontier has wider “wings” and are perfect for sleeping children. The “wings” are farther away from the head and are angled just right as to allow sleeping and looking out the window. The “wings” are thinner and have more of a “big” kid look. This thinner look in NO WAY implies that Graco is safer for the thicker “wings”, as Britax states that its wings are “true side impact protection”. Graco does not state this. The plastic around wings appear to be of stronger material on the Frontier, even though they are thinner. Frontier also has the “hugs” system on the harness to minimize forward head movement. Graco does not.
    #7 The Graco has only a 12.5 inch seat width for the child to move around in. The Frontier has a 12.5 seat area around the tush, but opens to a spacious 17 inch wide seat. This may not be an issue for the younger kids, but the older ones need more space. This may, however, be an issue for small cars.
    #8 Cup holder and “hidden” storage are neat in the Graco. The Frontier has 2 cup holders, but they can not both be out, as one hits the door when installed on far right or left. The cup holders also do not go smoothly in and out when installed in the vehicle, as the seat blocks the cup holder from retracting. This does not happen when the seat is not snugged down, but when installed….. This is not too much of an issue as we just leave them out. This is only an issue when I have a third child trying to walk to the back 3rd row between 2 Frontiers with cup holders out!

    Bottom line. If you need a car seat around the time that Britax has a sale, I would get it over the Graco. The price difference at that time would only be $50. I think that your big kids will be happier in the Frontier. If you have a smaller child, remember, he/she will be a big kid soon!

    Would have been a 5, except for one thing…, January 29, 2009
    Dad of two boys (Lewisville, TX) –

    The crotch strap.

    This seat looked ideal in every way. I liked it right out of the box, and when I put it together. It was exactly what I was looking for.

    Then, I sat our average-sized 3 1/2 year old in it, boxed it up and sent it back, very disappointed.

    The crotch strap, in the closest position, was beneath the back of my son’s crotch. In the farther (and only other) position, it was even with, and slightly pressing against, the front of my son’s crotch. In other words, no room to grow whatsoever. There is no way possible that this seat would allow my son to sit comfortably in a five-point harness all the way up to 65 pounds. At that point, the strap would be well beneath his crotch and be uncomfortable and dangerous. No way… and I really wanted it to. If there was one additional slot for the strap, an inch or so farther out, this seat would be PERFECT, in my opinion.

    So, I gave this seat a 3 out of 5. For a younger child, or one just reaching my son’s age and size (again, he is very average in weight, height), I would probably rate this seat a 5. But, since it clearly will not be able to do what it says it should do, up to 65 pounds, I cannot give it a 5. I honestly don’t know how any child can be accomodated in this seat up to 65 pounds, unless they are a very, very skinny 65 pounds.

    If Graco updates this seat to add one extra slot an inch or so farther out for the strap, I would buy it again immediately. I was, and am, a little angry that the seat won’t work as advertised. Buyer beware; look up the few other comments on the crotch strap first. Then, please, go to the store and “test seat” this seat before buying, and please consider how big your child will be at 3 1/2, or older. Otherwise, you may find the same disapointing fact I did.
