    Great alternative to Nautilus
    1/21/2013

    Customer review by daddy2princesses

    by daddy2princesses

    We have the Nautilus (pink) by Graco and wanted a cheaper/comparable option for our 2nd car. As we have 2 girls (ages 3,4) we prefer not to spend $400 on car seats but wanted to keep them safe. Although we have been to car seat safety inspections, I don't feel my girls are big enough (40lbs,40in) to be in safety belts alone with highback boosters, this is much safer in my opinion. We prefer harnesses. With that said, here's a comparison of this 360 vs the nautilus. You make the call if it's worth the price increase. Nautilus advantages: -Arm rests are higher and have built in storage -Headrest goes about 2 in higher maxed out 360 advantages: -Put together with a large bolt instead of just snap in clips on the nautilus -Price is about $30 less (even better with walmart $20 back credit card deal!!) -Top straps adjust with single hand headrest movement (no feeding straps through holes like nautilus) Headrest adjustment is right behind logo and slides up nicely. -Leg/crotch strap adjusts front to back through an 'I' shaped channel - a bit hard with big hands but still easier than feeding the entire metal through a plastic hole like on the nautilus Overall both a pretty close in size and features making this a great comparable car seat to the highly rated/reviewed nautilus. My girls should be safe until their at least 6 or 7 as this fits kids up to 65lbs and over 50"

    Although this seat is Not a convertible seat like it's labeled, it does still make a great booster seat. For all of the features you get, it really is a good deal. The headrest adjusts and the straps auto adjust with it to accommodate your growing toddler without having to manually retread the belts to the next height shoulder slot. It has a belt tightener in the front for easy and secure fit. The shoulder pads Are very comfortable and the chest clip is very secure. It's the type that is used on much more expensive car seats. I really prefer it! It's very sturdy, not to mention easy to covert to a backed booster and a booster with a seat belt when your child is ready. The last car seat you'll have to buy! These features are usually found on way more expensive seats, but for half the price of those, with just as much quality. I'd definitely recommend. But remember these are NOT convertible seats and are forward facing only. Please don't buy unless you have at least a one year old child that's at least 22 pounds. Weight doesn't make up for age. Don't put any baby under a year old! We bought this for my two year old nephew and he loves it. My ten month old climbed in it and actually fit pretty well, and he liked it too. Thinking of getting him the same seat when he is old enough. Enjoy!

    Got this seat for my forward Facing 4 year old. I got it b/c of it's 17.5" seat base. I was trying not to have to buy two Diono Radians but needed a VERY slim Compaq seat that would fit 3 across in my VERY SMALL sedan. When all was said and done it works. Benefits, the cup holder, it moves from one arm of the seat to the other AND swivels so it is useable even though my seat is smashed up against the another seat in my car. I wish there were more color options but am happy with the fabric type, it seems like it will be easy to clean. This seat dose not allow for any over hang off the car seat, I had over hang so I emailed the company photo's they responded with in 3 days asked me a few questions and had a suggestion, I made the changes and sent new photo's and they approved the over hang. It's also nice to know that when my 4 year old grows out of the harnessed & high back use of this seat she'll be able to just use the booster portion of the seat.

    Customer has been confirmed to have purchased the item from Walmart.

    We got this seat for our 2nd vehicle so any of our 3 kids could use it. We tried it in out primary car first. The seat is narrow, almost as narrow as a Radian, and fit 3 across in our car. The seat is easy to put together and very lightweight. The LATCH connectors are the old type and not the push button kind. The seat itself is very tall, 5 or 6" taller than the Radian RXT and Britax Frontier with the same height child in it so not a good thing for our car as it decreased the visibility out the rear. The seat was fine for our 2 yr old and 4 yr olds on shot trips but there was crying on trips longer than an hour, something that does not happen with the other seats we have. In all this will be a good second vehicle car seat for occasional use and it's cheap price and lightweight constriction add to that estimation. If you have a tall child you'll want to contact the manufacturer when you get your seat and they'll send you a crotch buckle extender (actually a longer belt) so the harness can really be used with children taller than 42".

    I bought this seat a year ago fort my big 3 year old who was outgrowing his convertible car seat. I loved the IIHS rating and good reviews. It fits well in my Infiniti G35, my son can climb in easily, and the cup holder is handy. It's heavy, but I like the sturdy weight. I just ordered one for my in-laws to upgrade the seat in their car. Great buy!

    • A. Read your manual, if you got this seat second hand or from someone you can download the manual at http://www.harmonyjuvenile.com/index.php. It's very simple to assemble and it comes in two pieces. There are two bolts on either side of the bottom seat as well as a bar across the back of the high back. It only took me a few min. to figure it out.

    • A. if you are talking about a seat belt lock off like what is used in an infant seat base, then No. It does come with a belt lock off clip included. If you buy this seat second hand you can contact Harmony and I'm sure they would send you a lock off clip at no charge. If your car is new enough & your seat belts should lock off them selves buy pulling the seat belt/shoulder belt all the way out and it will lock.

    What is the maximum height in this carseat using the 5 point harness? Also at what level are the straps in the maximum height position?
    by ZmcSncmomma 1/28/2013
    6 answers
    • A. This is a VERY old question but the manual states the Max height in harness position is 57". This seat has a 1-hand, no re-thread harness height adjustment and a 9-position, 1-hand height adjustable headrest that extends to 29". SO there isn't really a "level" for the strap hole.

    • A. The manufacturer says 57" but I don't see a way a 57" child could sit in these harnesses. I was trying out the harnesses to see how long they would fit my tall boy (currently 45" at 4.5 yrs). I put the harnesses at the highest slot and could barely buckle my son in. The belt is not long enough. When my son is tall enough to warrant using the highest harness slots, I won't be able to buckle him in (and he is of average weight). HTH!

    • A. The top harness slots are 18.5". I don't think it gives a total height limit, but if you measure your child's torso height you can figure out how long they have. (Have them sit against the wall and measure from the floor to the top of their shoulders. Most kids grow 1-1.5" of torso height per year so a child with a torso height of 14" would have a good 2-3 years at least before outgrowing the harness.)
