    So far so Great!

    5 out of 5, reviewed on 06.10.2008


    I have a 6yr old, 4yr old, and 2 yr old and have been a very loyal Britax customer and have owned two Roundabouts, two Regents, and two Parkways over the past five and a half years and thought I would never use anything else but I am very happy with this seat and plan on buying two more. I had two Regents and a Roundabout in my car and it was a tight fit and on top of that I couldn't stand how difficult the Regents are to get in and out of the car. They are so heavy and very awkward to handle. They take up a lot of room and while they are very nice after two years I just can't handle the difficulty of taking them in and out anymore. I put all my Britax's up for sale and I'm changing all three of my kids seats to the Graco Nautilus's. Here is what I like about these seats that I believe are lacking in the Regents...
    *Cup Holder
    *The 3 in 1 feature
    *Easier for my kids to buckle and unbuckle themselves
    *Took me way less time to install even considering the fact that I put it together in the trunk of my suv in the Walmart parking lot.
    *Height, I like that it sits up a bit higher so my kids can see out better
    *Size, saves me several inches of room in my suv
    All in all the Regents are nice if you never take them out and if you have two or fewer kids in your car. They do seem to be made of higher quality materials however I have three and do have to take the seats in and out on a few occasions and can't stand the hassle anymore. Love these seats and hope you at least give them a try before you did what I did and spend $280 per Britax seat.

    From Infant carrier to the 3 in 1 car seat I really like having more room unlike the big bulky ones I have used in the past. This car seat provides enough room for the other two booster seats we use in our Truck's 2nd row. My little one seems to like it as well. I look forward to using the next two feature's this car seat provides.

    Car Accident

    5 out of 5, reviewed on 07.07.2013


    I purchased this car seat in December of 2012. In June of 2013, I was in a serious, high speed car accident. My 3 year old son was in the car, safely buckled into this car seat. After fish-tailing and 3 impacts into a guardrail, the car finally came to a stop. We both walked away from the accident. I had severe whiplash to my neck and back but my son never once complained of pain or acted like he was uncomfortable. I believe it was because of this car seat. It protected him 100%, despite the fact that the first impact was to his door. I won't even consider buying another car seat or booster seat. Accidents can happen and do happen in a blink of an eye but now I know first hand that my son will be safe. That is priceless.

    I went to so many different walmsrt stores to find this car seat. I have a 2.5 year old that is big (37 lbs) and very tall for his age. This seat is so well made. The side acctually seem to go around their head to protect them in event of a crash. It also looks like big brothers booster so he thought it was a "big boy" booster =) It is the least expensive car seat that goes to 65lbs that does not require a headrest for proper instalation. This seat was easy to instal, easy to adjust and will convert as they grow older!!
    It is hard to find. So far only Walmsrt is selling them

    Wonderful Carseat for Half the Price!

    5 out of 5, reviewed on 01.28.2009


    The seat overall is pretty heavy, so if you have to lug this thing around, I would suggest another seat. But safety wise, it seems to be pretty solid and is indeed reinforced with metal in the back. I was very impressed with the wraparound headrest. In the pictures, it doesn't even look like it comes out, but it really looks like it would offer a lot of head support in a side impact crash. The headrest is also covered in foam under the padding so I know that it would help. It was very easy to set up, but make sure the harness straps are not caught under the padding and come out from the right place in the seat.

    My son is 2 and small. He is 25 pounds and 34 inches tall, so I was concerned that it would be too big. He fit perfectly and he loves his new seat!

    It was a breeze to install although a bit heavy to carry, but I don't plan on taking it out of the car anytime soon.

    The button to loosen the straps is easy to use, but it is actually a lever that you pull up instead of pushing down. It seems like it would be hard to tamper with if my kid ever tried to loosen the straps himself. The straps do get twisted, but they do that with my Britax as well. You just to make sure they are untwisted when you buckle them in.

    I LOVE how the seat will hold a child up to 65 in the harness. It is sooo much safer than a belt. This carseat will probably be the last one we'll have to buy for my 2 yr old son since it grows with him.

    We also have a Britax Roundabout which we loved, but we didn't want to spend $300 on a new one when the younger sibling outgrew his baby seat. This seems to have much more surrounding support for the head than a Marathon or a Roundabout. You can see from the photo, I compared the two, so you can see the difference.

    This carseat, overall was a great buy. I will buy another for my younger son when he grows out of the Roundabout!

    Excellent car seat. Wish I had this with my first three. However, some display signs may lead one to believe that it is a rear facing seat. It is not.

    I still love it and would recommend it to family ; )

    I bought two and my girls love it! I have twin baby girls that hated their rear facing carseats, to the point where we couldn't leave the house because of the constant tears. As soon as I placed the girls in these seats to test them out, they glowed. Great product!

    I have bought 4 of these. One recently for my mom in her car. A few months ago we were hit by a drunk driver on I 10 in Beaumont, TX who was going about 100 miles an hour...he hit my daughter's side of our truck. We had gone up on to a concrete barrier and slid down it about for about 200 ft...truck completely totaled. My daughter didn't know what happened but wasn't shaken. The car seat had kept her head from whipping side to side. Even the fire fighters who showed up on scene commented on how awesome this seat was. So because it was in a wreck I had to buy a new one and we have one in our other vehicle too. It saved my daughter's life on top of someone up above looking out for my whole family in the truck that evening.

    life saver

    5 out of 5, reviewed on 02.23.2011


    We were recently in a very bad car accident, I rolled my F-150 pick up truck going 65 mph. I had bought this car seat more for style than anything. It was a life saver. My 2 year old son was in this seat and the car seat held up the roof of the truck! My husband and I had critical injuries but my son walked away without a scratch! The seat saved my son's life! I have since then bought 3 more seats just like this one. People say I'm crazy for spending the extra money but how can you put a price on something that saved your children's life. Absolutly would recommend this carseat to ANYONE!

    I bought this seat two weeks ago for my six-year-old and we both love it. She's pretty close to 40 pounds and was about to outgrow her current seat. I'd like her harnessed a little longer in one of our vehicles that has "backseat issues". I was thrilled when this seat came out. I really like Graco products and since this was more of a want than a need, I couldn't justify $300 for some of the other higher-weight-harnessing seats.
    Putting it together was a little weird. It was difficult to pop the arm rests in. It's supposed to make a click, but it was a very quiet sound. They must be in right, though, because she puts her weight on them getting in and out and they haven't wiggled.
    The strap adjuster took some time to get used to. It has a shield over the release so a child can't loosen the straps. But this also means you can't see it, so you have to feel around for it.
    The cupholder is great. It actually holds a real bottle of water rather than just a sippy cup. Big kids use water bottles!
    I've installed it in my Camry with the lap/shoulder seatbelt and it went in like a dream. It will eventually be in the Jeep Cherokee. Although I haven't tried it in there, I don't anticipate any problems.
    The headrest sticks when you raise and lower it, but it should loosen up and that won't need to be done all that often, anyway.
    Be sure to pay attention to the specifics. Children must be one year old and weigh 20 pounds (both, not either/or) to use this seat and it's forward-facing only. Even though you can use it at 20 pounds, I'd recommend leaving your child rear-facing until 30-35 pounds (depending on the seat) in a convertible seat. Not only will your child be much safer, you'll get more use out of the Nautilus. Since it expires after six years, if you buy it for a one year old, it'll expire when he's seven and you'll need to buy another booster. If you buy it when the child is three, it'll be good up to age nine when most kids can go into a seatbelt.

    Recently we were involved in an accident on the freeway. We were rear ended in the slow lane, which caused us to cross all lanes of traffic and hit the center divide head on and roll over. The only passenger of my vehicle that is 100% pain and injury free, is my 5yr old son who was riding in his Graco Nautilus Bravo in the rear center seat position of our vehicle.

    I have these seats in each of our vehicles and will now purchase a replacement seat for the car seat that involved in the accident. The car seat itself does not show ANY signs of stress from the accident, but it will be discarded properly after being involved in such a forceful accident.

    I fully attribute this car seat, the car seat being properly installed and secured in our vehicle to our son's pain-free results after such a horrific accident.

    I bought this as a back up seat for my 5 year old in my husbands car. he typically rides in a Britax Regent, but I didnt want to spend that much on an occasional use seat. I'm very impressed. He has lots of growing room. The pad is to be removed when the harness isnt on the lowest setting. I plan on replacing my daughters seat with one with she has outgrown her seat RF. We practice extended rear facing(my daughter is 27 months old and still RF) and exntended harnessing. This seat really does fill a gap that is needed in the car seat market. Great job Graco!

    Awesome Seat!

    5 out of 5, reviewed on 02.29.2008


    We have a Britax Marathon and we were looking for a backup seat for grandma's car/etc when we found this one.
    The only thing I cared about in a seat was that it harnessed longer than 40lbs, and this one does! up to 65lbs!
    We got it home and had to keep it in the living room for about a week because my daughter fell in love with it. I love that it has a cup holder and cubby holes on both arm rests for all her little things she's just gotta take with us in the car.
    my daughter is 3.5 years old 36inches tall and 38lbs
    She's still on the bottom slot for the belts on this one with the headrest pushed all the way down so this seat will last a very long time, also it turns into a booster after 65lbs, which means we don't need to buy another seat ever again for her!
    The set up was a little funky, but after looking in the book it wasn't hard to figure out. Easy to install for either the latch system or in my case normally, the seat belt.
    We've only used it a couple times, but my daughter looks very comfortable in her new seat! The britax seat only has one more slot left, so I think she'll be out of that one in height WAY before this one!
    I reccomend it to Everyone looking for a seat that harnesses for longer, but is less pricey than other seats that do the same thing.
    Thank you Graco for making this Seat!!

    This is an awesome seat! My son (a BIG 28mo. old- 38lbs/39") absolutely LOVES it! I love that it harnesses to 65lbs and will more than likely actually get him to 65lbs in a harness because of the harness slot height! (keeping your preschool'er in a 5 point harness until they are mature enough for a booster (usually age 6) is the safest thing you can do for your child) When he's ready for a booster, it will make a great belt positioning booster seat. Don't waste your money on anything else...this seat has it all!

    This carseat is fantastic! I also, like some of the others have a big 2 1/2 year old. I did a ton of research a couple of months ago to find a big booster for him and at that time, I found the Evenflo generations seat. I liked it, but then I happened to see this one in Wal-mart. The Evenflo is being returned! Oh my word, I knew I would have to have it. Of course the store I was in only had the display model. I had to call around to all of the surrounding stores to see if they had one, even though the online info. said they did, some did not have one. I finally found one and they held if for me. So I drove an hour (which took me almost 2 hours) in the snow and picked it up. I'm so glad that I did! We love it!
    It's big and sturdy and will hold up to my son. I don't feel like it's going to break when I set him in it and I love that it can grow with him. The other seat we had, the straps were already to the highest position, in this one, we still have one to go! The head rest is awesome. He fell asleep in it for the first time today and his head held in place, unlike the other one. He loves it. Oh, and the straps are so easily adjusted, it's a dream come true! I recommend this to anyone. Good luck finding one. I called Graco and yes, right now for awhile Wal-Mart is the only store to have them and they are hard to find. Be patient and WAIT for this seat, I promise you'll be glad you did!

    This car seat has it all! This is one stop shopping for children OVER a year or over 35 pounds! Only reason I gave it 4 stars is because it does not say anywhere on the box or in the description that this is a front facing seat only. It is dangerous to put an infant in a front facing seat until they meet the requirements so I had to purchase an "interim" seat. My son had outgrown the infant seat, but not yet ready to face forward.
    That said, this seat looks great, is very comfortable, and will be able to grow with my child. I tested it out in my Subaru Forrester and it fits perfectly and works great with the latch system.

    My husband and I bought this carseat for our 3yr old son...We already had another one, but wanted to get another one so we could both have one in both of our trucks. That way we would not have to switch it out, if my husband was gonna take him somewhere in his truck. Anyways, I did a lot of looking around and reading the reviews of many carseats, and decided on this one. I do like how the 5 point harness goes up to 65 pounds. My son is already 3 ft 5 in at 3 yrs old...tall for his age, and weighs about 42 pounds, so this is perfect for him.

    I did read the reviews about how it is not a good one for sleeping, how it doesnt really recline too good. Well, I dont know if it depends on what car/truck you have...but, in my 2008 Dodge Truck (quad cab) it is perfect....I guess it is how my seats are, because my husband didnt even have to recline it back...it is already perfectly reclined for my son. So, his head will not be leaning forward if he falls asleep in it.

    I love that it has a cup holder.....my son thinks it is the coolest thing!

    My son and I will be driving up to Northern California in May to go visit my new nephew, and I am very comfortable knowing that he will be comfy and safe in it as well. It will be about a 6 hour drive for us...and I know he will be just fine!

    I would definitely recommend this!!!

    My wife and I struggled through a sea of car seats as our first born out grew his rear facing seat. So many to choose from at so many different prices. We typically worry and just pay top dollar for things because it's our baby after all. We found this one on many different websites all with great reviews. Wal-Mart had the best price - low enough to make us worried about quality. Let me tell you - this seat is great! Our son isn't a "car baby" and frequently would cry the whole time in the car. On the FIRST trip facing forward and comfortable in this great seat he was smiling and laughing. Huge transformation. We just did an impromptu 21 hour (each way) road trip for Thanksgiving from Mass to Florida to visit family. Despite everyone I know calling me crazy for the trip with a baby (15 months old) who hates car rides, it was no problem. He loved it and barely made a fuss. Only difference was this seat. Sounds crazy but we love it.

    We purchased 4 of these after deciding to harness our small children past 40lb. Our children are not going to be tall enough to use the seat belt correctly on the cheaper seats we had in daddy's car, and our better seats didn't fit in his car correctly.......so we started all over with these.

    Our kids are 2 (20lb 32 in) and 4.5 (33lb 40 in) and love them. Our 4 year old can buckle and unbuckle himself, which is helpful. Our 2 year old loves the fact hers is just like brothers. They each love the little cubbies and can both reach their drink. Both kids have slept comfortably in them as well.

    They were easy to set up and install and installed rock solid in both our Chevy Uplander and Buick Rainer. I will say the seat is a bit heavy, but we don't ever take ours out. Their safety means more to us now than ever since a stint in the hospital for one.

    I am glad we took our pediatrican's advice and got new ones so we could harness them longer.
    We purchased 2 in store, and then ordered 2 more on line.......saved $15 on the second set.

      This seat is forward facing only, please check your states requirements as to the minimum age a child can be forward faced.
