Perfect not bulky

[This review was collected as part of a promotion.] My child loves her new seat it's slim & comfortable, I went with this car seat because it's not bulky, it has a metal frame and all around seems like a good seat for children.

Nice for preschool age and up

Purchased for my 4 year old grandson. Works well for him. I like that it can recline and he can use it as he gets bigger. Only thing I would change is the anchor clips. Would be easier if it had the buckle type rather than the clip type.

Big Kid Seat

[This review was collected as part of a promotion.] My 4.5 year old is so excited to move into a “big kid” seat with armrests and bigger cup holders than his convertible infant seat. Super easy to put together and install.

Love this car seat

My husband bought a newer truck. So we needed a seat for his. First off we had a different Brand before we purchased the nautilus. The other brand was a nightmare to install and we never could get the seat anchored to where it wouldn't move. We ordered the nautilus right before we went on a weekend trip. The car seat arrived very quickly. Once we received i put it together and put in my husband truck in about 20 minutes. VERY easy to install and fits perfect in his Toyota Tacoma. My daughter loves it! We've had this car seat for about 2 months and have moved it between different trucks at least 5 times. Each time has been very easy to remove and install. So happy with our purchase.

3 year old car seat sent

I love this car seat so we bought a second one to have in my husband's car. Just received it and it's already 3 years old. Sending it back. Sad as it's a great car seat but can't keep buying new ones every couple of years just these are being sent with only a half life left in them. They should be marked down much more when they are this old.

Easy to use and install harness booster seat.

This is a great seat, very easy to move the shoulder piece up as your child grows. No need to uninstall the seat and move the straps as in other models. We had purchased one for our older child 2 years ago and liked it enough to get a second one for our younger child. This seat met our requirement of fitting nicely in a sedan. We also love that it will carry our kids through the booster stage.

2nd purchase!

[This review was collected as part of a promotion.] I bought my first seat 5yrs ago for my son. It has been is favorite seat, has held up amazingly well, is solid & sturdy. So I just bought another one for my daughter who needed to upgrade. They are a heavier carseat & are not the simplest to move from car to car but that is ok for me. I prefer a solid build seat to protect my kids. This seat does not dissappoint!

Awesome carseat

I am a grandmother and have purchased 3 car seats and 2 strollers.... they are the safest and best quality on the market... the latest purchase was due to an accident that could have been so bad but no one was seriously hurt... there were 2 kids in the back in this seat.... thank you so much
