Graco Nautilus 65 3-in-1 Car Seat.

Graco Nautilus 65 3-in-1 seat review is a prime example of not knowing what you don`t have until you realize there`s so much more out there for you to utilize as a parent, keep your child safe and allow them to enjoy the ride.

What is Graco Nautilus 65 ?

Graco Nautilus 65 is a harness booster car seat that was first introduced by Graco in 2015.

Since then, this seat has gained prominence and reputation among the young families.

According to Graco, this is probably the last seat you`ll ever buy for your kid.

While the Graco`s versatility captured my attention, the safety and durability of the seat kept my interest on the seat.

Aptly named 3-in-1, the Graco Nautilus comes as a harness booster car seat that can be used as a forward-facing with harness car seat for your 22-65 lbs toddler, then converted into a high-back booster car seat for the 30-100 lbs kids and finally used as a backless booster car seat for 40-100 lbs kids who are no longer comfortable with high-back booster mode.

In this Graco Nautilus 65 review, we shall explore everything you need to know about this seat, including its features, functioning and cons to help you make an informed decision.

Key Features of Graco Nautilus 65 3-in-1 Car Seat​

Safety First, as Always

A good car seat is needed for your kid`s safety.

So what are some of the safety features on the Graco 65?

1. Steel Construction

The safety of the Graco 65 is undeniable.

Constructed with Graco`s proprietary SafeSeat engineering, this seat is durable and reliable.

The SafeSeat engineering combines the plastic frames with the steel frames for the ultimate safety for your kid.

While the steel reinforcement is a pretty safe choice, it adds on the bulkiness of the seat, and this can make switching the seat from car to the other a tad hectic.

But this should be a non-issue provided your toddler is safe, right?

2. Safety Surround Side Impact Technology

With car accidents being the leading causes of death in children from ages 1-3, having a car seat with excellent ratings should be a priority.

Graco 65 has been thoroughly tested to ensure it`s completely safe. The seat has even gone through a side impact safety test by NCAP, and it has proven that it can withstand a crash twice better than the national standards set by NHTSA.

In a nutshell, the Graco is a remarkable choice that meets and exceed all the safety requirements.

SimplySafe Adjust Harness System

If you`ve ever tried changing a car seat harness from the back of the seat with the clips and belts, you know how challenging it can be.

Now, with the SimplySafe technology, you can now adjust the harness and headrest in one motion.

The adjustment process is quite simple.

Beyond the simplicity, the open loop belt guide on the seat will help you in placing your car`s seat belts through the car seat with ease.

This feature is quite handy especially when you`re transferring the car seat and for quick replacement.

EPS Material

For the ultimate safety, Graco has included a lot of EPS foam padding, and this helps in absorbing the impact in an accident. The padding will help in drawing the harm away from your little one.

Moreover, the padding will stand up to the very energetic kids who are always hard on the seat.

Alongside the foam padding is the three-position reclining feature for the ultimate comfort. Contrary to the un-reclined seats, the Graco will not have your kid`s head bob from side to side when they fall asleep.

Heat Management

During the summer, it can get really hot, and temperatures can soar to unbearable levels.

To avoid the uncomfortable conditions, Graco designed the Nautilus 65 3-in-1 seat to withstand the hot temperatures. This is quite handy since the temperatures can reach up to a whopping 124 degrees Fahrenheit.

Unfortunately, the claim is not backed up by any test.


Undoubtedly, the Graco 65 is a safe option, and this is obvious.

What about its biggest selling feature: the different modes?

Let`s have a look.

3-in-1 Mode 

The convenience of having a single car seat that will work for three different car seat types is a huge plus to any dad or mom.

With the Graco 65 you can use this seat in three ways;

  • First, you can use it as a regular seat, and this is in the case with the older babies.
  • Secondly, you can turn the Graco 65 into a belt-positioning seat.
  • And finally, you can transform it into a backless booster seat.

The configuration of this seat is in line with the AAP, which recommends that toddlers should stay in their seat as long as they can snugly and safely fit according to the manufacturer`s limits.

When they`re all grown up, and at the final stages of their childhood, AAP recommends that they move to the booster seat, and this should be done as long as they`ve outgrown other modes and they can fit on that position. Ideally, this should be anywhere between ages 8-12 depending on their size.

Besides meeting all the stipulated requirements, the Graco saves you from purchasing three different car seats, but instead get all the three in one.


According to some of the Graco users, the Graco Nautilus is durable and offers a generous life span of six years, which is standard, but the simple booster seat portion offers eight years.

At the very least, this should be enough for you to raise your kid.

And when you`re done with this car seat, you will feel that it was a worthy investment since it will have served you to the maximum hence you will gladly dispose it.

Graco Nautilus 65 Review- Other Features.​

Presence of Cup Holders

If you`ve ever taken your kid for a ride, you know how frustrating it can be having to stop every ten minutes to pick something they`ve dropped.

With the Graco, you can safely secure your kid`s drinks and cups on the seat. While the cup holder will not prevent spilling, it`ll certainly help.

Simple Transitioning

With a multi-position system, you might get tempted to think that the Graco Nautilus is challenging to install.

According to Graco Company, Graco Nautilus 65 is intuitive thanks to the simple installation system that is further underlined by the presence of red indications that will direct you on how to do it.

The installation process is quite easy as you`ll simply need to fasten the car seat using the seat belt, then passing it between the seat pad and the shell. While at it, it`s crucial that you ensure the belt passes through the plastic lock off.

Similarly, using the Graco Nautilus 65 is also an easy affair as it only requires fastening of the belt of your kid then looping it over the shoulder guide. The good thing with using the seat belt is that the red line acts as the guide to follow.

In case you have an older kid, you`ll still follow the above setup, only now that you`ll need to adjust the headrest.

If you`re still in the dark on how to go about this, the seat comes with an easy to follow manual that will instruct you on the right way to do it.

If you`re a modern dad like I`m, you`ll only need to do a YouTube search on how to get the seat in place.

What users love about the installation process is that it will require zero tools, which is great news to many of us who are not DIYers.

What We Don’t Like About the Graco Nautilus 65

Like most of the car seats, the trouble of cleaning them continues with this one. While cleaning of the pads is not an issue, the struggle of removing the seat pads from the Graco and putting them back on is a real struggle.

Another issues with this car seat is that it`s relatively big and will consume a huge space on your car, and this is quite a deal breaker, especially for those with small cars.


Undoubtedly, the Graco 65 comes with high safety ratings, side impact strength and the steel frame- all amazing features that you don`t see in most car seats.

The sturdiness and safety of this car seat make the Graco Nautilus a great buy overall. Moreover, it`s priced reasonably, especially considering the above average safety features plus the amazing ratings.

Though some parents find it bulky, the extra pounds are by no means a deal breaker, provided it keeps your kid safe and provide him/her with a pleasurable riding experience.
