Awesome Seat!

[This review was collected as part of a promotion.] I bought the seat when my 3-year-old was ready to be forward facing. The seat she had was very difficult to strap her in and I didn't want to spend the rest of her time in a car seat fighting with buckles. This car seat was so easy to install, it doesn't take up too much space, she's super comfortable in it, and best of all she's easy to strap in. I loved this seat so much that I bought another one for the other car. Highly recommend!

We love it! Super easy install!

[This review was collected as part of a promotion.] We moved to this when my kiddo moved to forward facing, as I didn't like the way our old seat installed forward. It was super easy to put together, and even easier to install! So easy, I uninstalled it and reinstalled it just to show my friend how easy it is! The harness moves super smooth, and adjusts nicely. My kiddo loves this seat. She's super excited that she has armrests like mommy. 100% recommend! Will be getting a second one when our next child moves to forward facing!

Overall experience

[This review was collected as part of a promotion.] Installation was very easy. Besides following the instruction manual, there are also helpful installation videos available on YouTube. Overall, the car seat looks safe and comfortable. The fabric feels soft, although my niece tends to sweat easily, so it can get a little warm during the summer. However, with the air conditioning on, it hasn't been a major issue. Since this car seat doesn't have extremely deep side bolsters, I think it may be a better fit for slightly older children who prefer a roomier seat. A couple of things I wish could be improved: the side headrest padding feels a bit firm and doesn't have as much cushioning as I expected. Also, there are only two crotch buckle positions. Having one additional position would provide more flexibility. My 5-year-old niece is already using the outermost slot, and when she wears a fluffy dress, the buckle area can feel quite snug. She has occasionally mentioned that it feels a little tight and uncomfortable. That said, for this price point, I really appreciate that this is a 3-in-1 car seat with a steel-reinforced frame. The overall safety design gives me peace of mind, and I feel confident keep using it.

Comfortable and easy for my child to use

[This review was collected as part of a promotion.] My 4.5 yr-old child transitions from a 4-ever car seat to this. He like it, saying it's less hot and more comfortable. It's lower, easier for him to get in (win-win) and he can now buckle himself.

Great car seat

[This review was collected as part of a promotion.] The adjustability is perfect for a growing kid and the comfort for him is a win. He loves his new seat and we love how affordable it was. It's very easy to install and change. 5/5!

Exceeds all expectations!

The Graco Nautilus 3-in-1 car seat arrived exactly as described and exceeded my expectations! Instructions for installation were completely clear and the car seat was set to go in under 10 minutes. Love the look- the pop of color on the trim is very attractive. The storage compartments on the inside of the seat arms are easy access for the kiddos- a great place to stash toys and snacks. The seat is easy to install in the car and I have peace of mind that my littles are safely secured and protected while on the road. The quality and value of this particular seat are apparent- double thumbs up from this satisfied momma!

Love the color

[This review was collected as part of a promotion.] We chose this car seat because it has the option to recline, however, the recline feature is quite difficult to use depending on your backseat. Otherwise, we live the color and the adaptability for it to also become a booster as our kiddo gets older.

Comfortable, safe carseat; needs shoulder straps

[This review was collected as part of a promotion.] I like the car seat and my kids always say how comfy it is but I wish it came with shoulder pads on the straps. After riding in the seat they end up with a line across their neck from the strap. I had to buy pads to go on them so it doesn't become painful.

Do not buy

I was sent a car seat that was three years past its manufacture date, Graco states it's "out of their control how long products are sitting on their shelf's" . At this price, selling a three year old car seat is insane granted that it's good 6-10 years so that makes the lifeline shorter. On top of that, I have yet to get a refund after returning. Do not buy this car seat from this website.
