Safe and Secure

The essence of purchasing a child car seat is to ensure the safety of the most precious passenger in the car. So regardless of the brand, you opt for, the safety of the car seat must never be in question.

Luckily the Nautilus 65 comes with a good number of interesting safety features that make it not only safe for your kiddo but also durable and reliable.

The restraint basically consists of a plastic frame merged together with a good number of steel parts. The reinforced steel frame is what makes it incredible and safe for babies.

However, the choice of steel also has an effect on the weight of the seat, which might not be cool but still understandable. With a whooping weight of about 20.5 pounds, you will agree that this unit is better off confined in your car.

So except you’re heavyweight, you might want to leave it in one place to save yourself from the physical exertion.

In addition, this car seat also features a 5-point safety harness and EPS foam for absorbing impact. This is extremely important as it helps to keep your child safe whenever there’s a collision.

It will also interest you to know that this product has been subjected to both crash and performance tests and found to be completely safe for infant.

According to NCAP, this safety seat has two times more capability to survive a crash than the average convertible seat in the market. In fact, it doesn’t only meet all the safety requirements required for child car seat but also exceeds them.

It was very difficult for us to look away from all these.

Graco Nautilus 65 LX is Versatile

No doubt, convertible garco car seats are meant to grow with kids; at least, that’s why they are called “convertible” in the first place. Unfortunately, it’s not always as it seems. With many brands, the problem is either a low weight limit or a harness that is not adjustable or difficult to adjust.

Luckily, this is not the case with the Nautilus LX. With this convertible seat, you get a lot out of one restraint.

It’s not even the fact that it’s incredibly safe (which is pretty obvious) that makes this seat so attractive, but the fact that it comes with different modes which offer a simple transition for your kid. In other words, this is one of those child safety seats that grow with your child.

The Nautilus 65 is referred to as a 3-in-1 restraint because it comes with 3 different modes which include the booster seats, the backless booster seats, and the forward facing seats.

In other words, this is meant to graduate from a normal safety car seat for toddlers to a belted booster seat, then to a booster seat with no back support.

We highly recommend keeping your kids in the forward-facing seat for as long as they fit safely. Only switch to the booster seat when their weight or height is above the limit specified by the product manufacturer.

At all stages of transition, you will be required to disassemble some parts.

You will find instructions on how to do this in the owner’s manual or the company’s website. You can also check out Amazon or places like YouTube for video tutorials.

The process is really simple; it should only take you about 5 minutes to switch from regular to a booster. No tools are required; it’s a piece of cake.

Latching and Seat Belt

The LATCH system and seat belt option are other wonderful features of this car seat. You have the option to decide whether you want to use the seat belt or LATCH system for seat belt installation, depending on the one you find most convenient.

While Latching is recommended for this seat, it might give you a tight fit like when you use your vehicle’s seat belt. However, you may find the LATCH a bit more difficult to use except when converting the seat to a booster.

Recline and Harness of Graco Nautilus 65 LX

At a very tender age, kids don’t have control over the movement of their heads. As a result, a little snooze can put them off balance causing their heads to shake uncontrollably, which can be terrifying. One of the ways convertible seats help to prevent this is through various recline positions.

The Nautilus LX comes with three recline positions, which might not be enough to completely stop bobbling heads in some situations. This is because, most of the time the seat changes by about an inch when titled, thereby needing more recline. Except you are using a big minivan or SUV, this might be a problem.

This seat also features a 5-point harness which is pretty easy to adjust. This makes it extremely easy to loosen the harness straps. But getting them tight enough might be a little challenging; you will definitely need some muscles to do that.

Luckily, this convertible seat doesn’t require rethreading, which is a big plus for you. So you don’t have to worry about rethreading its seat straps to accommodate your growing kid.

Instead, you can grab the handle and pull up harness straps and headrest to create more room for your growing kid. This is supplemented by a bottom buckle which can be adjusted outward. This whole process saves you a lot of time and effort.

The same way normal car seats are designed with parents in mind, child car seats are also designed with babies as the prime audience. And for a restraint like the Nautilus LX, you can expect more than just a convertible nautilus car seat.

Padding for body support is also included for older babies. But this can be removed once the kids are old enough because they might not be comfortable anymore.

  • Highly durable and sturdy
  • Super safe
  • Machine washable
  • Doesn’t require rethreading

What You May Not Like

Like any other car safety seats, there are a few areas users have complained about when using the Nautilus LX 65; one of the closeness of the crotch strap.

Given that this seat is meant to grow with your baby, a close crotch strap can be a bit discomforting for older kids. Although this is manageable, it would have been better if the strap had an adjustment.

Also, you may find cleaning a little challenging as you may struggle to remove and replace the seat pads.
