In Their Own Words: Actual Users’ Reviews of the Graco Nautilus 3-in-1 Car Seat

better than radian or britax in my humble opinion – by Misstico (Bayside, NY)

“So I did a LOT of research before buying this, read multiple message boards, then to the store to look at them…I finally decided to go for it b/c of
1)price (though it really wasn’t an object) but I am a big fan of bang for your buck,
2)sturdiness, i was never a fan of graco until i bought this seat. It’s got a nice weight, sturdy frame.
3)comfort, memory foam! DD loves it, she sleeps very comfortably in it without slumping over like she used to.
4)size, not gigantic like the regent but large it enough to have a big kid sit in it
I was concerned about its looks but it’s much better looking in person.
Finally, who can beat amazon’s price!…”

A great 5-point option for a tall toddler – by E. Jayasuriya (Silver Spring, MD)

“We decided on this seat after we suddenly had to retire our Evenflo Triumph. Our son is a tall skinny 3-year-old and I wanted a seat that would let him stay in a 5-point harness as long as possible. The instructions were clear enough that 2 exhausted people could put it together and install it at 10:30 at night. Setting up the straps was pretty easy and adjusting them is VERY easy. The seat seems comfy enough, and I really like the head rest–my son can doze much more comfortably on longer trips now than he could before.”

Choosing the right car seat for your toddler can be a daunting task. After hours of research, it feels like you’re buying a whole car, not just a car seat. While there are many features available, the three most important are safety, versatility and comfort. This car seat covers the basics in a big way and then offers much more at a reasonable price. The Graco Nautilus 3-in-1 Car Seat is a great choice for parents that want to comfortably protect their young children from four-wheeled dangers without breaking the bank.

* Author’s note: While researching the Nautilus, I found a discrepancy in the listed weights on and the manufacturer’s website. I called Graco’s customer service number and the operator (who was very cordial) confirmed that the Nautilus’ correct weight is 21 pounds
