Graco Nautilus with Safety Surround Review

Graco introduced the Nautilus 3-in-1 forward facing combination seat in 2007. The Nautilus quickly became a trusted, well-priced staple in that category of seats.

The Nautilus harnesses from 20-65 pounds, then converts to a high-back booster, then to a backless booster.

Since it was introduced, the Nautilus was joined by two other Graco combination seats: the Argos 65 and the Argos 80 Elite.  All of these seats have a lot to offer the Littles who are forward facing — Littles who require a well-fitting harnessed seat that converts to booster mode to grow with the child.

There are a few varieties of the Nautilus, each with slightly different comfort or safety features. This review peeks under the hood of the Target exclusive model: Graco Nautilus with Safety Surround.

We’ll be taking a close look at the Nautilus with Safety Surround.  This model offers the same basic features and shape as the Nautilus, but adds some extra padding around the head area of the child.

The Nautilus can cause some head slump when passengers fall sleep; it has a bit less padding in the headrest.  We’d suggest the Nautilus with Safety Surround for children who often fall asleep in the car.

 

Assembling the Seat

The Nautilus arrived in two pieces — the base and back of the seat, with the harness attached and the headrest.

Use of the headrest is required. 

To assemble the Nautilus, line each post on the headrest up with the holes in the top of the seat’s shell and push down.  The headrest clicks into the top of the seat.

 

 

 

Installation

Over the years, I’ve owned a Graco Nautilus and the Argos 65 featured in this review.  I found that the neither the Nautilus nor the Argos installed in my 2009 Mazda 5 very well so when this Nautilus with Safety Surround arrived, I was pretty hesitant about starting to install the seat in my car’s second row.

I used all the installation tricks up my sleeve and after more trial and error than I care to admit, discovered the method that worked!

Recline the vehicle’s seat back about two clicks, install the Nautilus with the seat belt.  When all slack is removed from the seat belt, I returned the vehicle seat back to the upright position that my car’s manual requires.  Lo and behold, the seat was installed with less than an inch of movement at the belt path in any direction!

The Nautilus installs fairly easily in my Mazda 5’s third row — a spot that’s typically a huge challenge to get car seats installed.  By moving the recline block on the Nautilus to the  most reclined position, a little sweat equity helped get the Nautilus installed there. The Nautilus also installed without issue in our 2014 Prius V, in a variety of rental cars over the years, and on the flat bench-style seats in the 2004 Mitsubishi Endeavor that we used to have.

The 45 lb. lower anchor weight limit only applies to seats manufactured after February 2015.  Nautilus seats made between February 2014-2015 is 42 lb. Older Nautilus seats have varying lower anchor limits, please consult your manual.

Crotch Buckle Adjustment

On both my 2010 Graco Nautilus and my 2011 Graco Argos, moving the crotch buckle between positions was quite difficult. The webbing was slightly too thick to slide the buckle comfortably out of either position, the task required a lot of finesse, lining the webbing up just right, and often, some grunting and cursing.

I’m pleased to tell you that the 2015 Graco Nautilus with Safety Surround used in this review was quite easy to move between positions!

It can be placed in either position, the only restriction is that the buckle portion not be below the child — the child sitting on top of the webbing is fine, the child sitting on the buckle indicates that the crotch buckle needs to be moved to the outer slot.

 

Harness Height Adjustment

To adjust the harness height on the Nautilus, the seat must be uninstalled from the car.  This can be a disadvantage if the seat doesn’t install particularly easily in your vehicle.  This can be no problem if the seat installs easily in your vehicle.

 

Headrest Adjustment

In both harnessed and booster mode, the manual states that:  “The shoulder belt guides must be even with or just above the shoulders.”  The headrest can be adjusted without uninstalling the seat so it’s just a matter of squeezing the red handle at the top of the seat, then moving it up or down to achieve the proper fit.  The headrest should not cover the top of the shoulder straps in harnessed mode.

 

Padding

The seat includes a pretty robust extra pad.  Since it’s only designed to be used with children who are using the lowest harness slot, it’s of no use to us.  The lowest slot is a mere 12″, which is a setting that’s more for a child who’s about 1-year-old.

Since the Nautilus is a forward facing only car seat, we don’t consider the Nautilus an option for children small enough to require the padding — we’d suggest that children that young and that small ride rear facing, then switch to a forward facing seat when they’ve outgrown their rear facing car seat.

 

Harnessed Mode: Fit to Child

Preschooler

Graco Nautilus: 4 years old, 43 inches and 56 pounds

Graco Nautilus: 4 years old, 43 inches and 56 pounds

 

This model is 4 years old.  She’s 56 pounds and 44 inches tall.  Not only did the harness fit her well, she had plenty of room left in the harness.   This is great news — not all harnesses include enough length to fit children on the larger end of the growth curve so it’s nice to know that the Nautilus is an excellent option for children in this size range.

One caution: it’s likely that this model would outgrow the seat by weight before height.  However, the Graco Argos Elite 80 would offer her the same great harness fit and would likely last until the end of her need for a harnessed seat.

Graco Nautilus: model is 5 years, 4 months old , weighs 45 pounds and stands 45 inches tall

 

This model is 5 years old.  She’s 45 pounds and 45 inches.  She’s able to climb into the seat and buckle herself in without issue.  The seat fits her well — my only complaint is that the strap tends to twist a bit if I’m not keeping an eye on it when she buckles herself in and out.

She’s roughly 17 inches at the shoulders so she has about an inch of harness height left in this seat.  That could equate to about a year left of use in harnessed mode.

This model is especially fond of the cupholder and the two cubbies.  They’re already home to a few stuffed friends.

 

 

 

 

 

 

Headrest Position: Harnessed Mode

The manual states that: “The shoulder belt guides must be even with
or just above the shoulders as shown by dotted line.”

 

Harness Height Adjustment

Adjusting the harness is a two-step process:

1. Adjust the harness height by doing the following:

Unthread the harness by removing the loops from the splitter plate on the back of the seat, thread the harness through the next slot up while ensuring that each side of the harness goes over the red rollers on the seat.  Attach the harness straps to each side of the splitter plate, then pull the slack out of the harness to confirm that everything is attached correctly.

2. Adjust the headrest so that shoulder belt guides are even with,
or just above the child’s shoulders.  This may mean that the harness is coming from below the headrest in some instances.

Switching Between Harness and  High-Back Booster Modes

Removing the harness and switching the seat to high-back booster mode takes a bit of effort, though it’s not as difficult as the manual’s 13 step process might seem.  Here’s a streamlined summary of the process:

Remove the Harness

Uninstalling the Graco Nautilus

Uninstalling the Graco Nautilus

1. Uninstall the seat (if you haven’t already) by unbuckling the seat belt and disconnecting the top tether anchor.

3. With the seat’s bottom facing you, remove the crotch strap by pushing the strap retainer through the slot on the bottom of the seat.  Flip the seat over and pull the buckle from the top of the seat pan, to pull it completely out of the seat.

4. Pull on the harness adjuster strap on the front of the seat to lock the splitter plate into place.  It stores at the end of a plastic gutter on the bottom of the seat.
5. With the seat still facing you, grab hold of both shoulder straps and pull them out of their respective slots on the seat’s back.

6. On the rear of the seat detach 2 lower seat pad elastic straps from hooks.  Also detach the elastic straps that are threaded through the vehicle belt guides on the sides of the seat. Repeat on other side.

7. Pull the seat pad out-of-the-way to reveal the red buttons in the seating area .
Slide the buttons to release the back support from the base and lower it into a flat position.
Pro tip: Hold the back support or sit near a wall while doing this step to avoid having the back of the seat falling  back and hitting something when the seat back releases.

8. Remove harness straps from arms.
Pro tip:  Once you’ve removed the harness, store the harness straps, crotch buckle and any pillows in a safe place for future use.  I put mine into the seat’s original box.9. To convert the seat to high-back booster mode, at this point, move the seat pad fabric out-of-the-way, then raise the seat back so that both arms LOCK into the gutters. You should hear a CLICK when the arms lock into the gutters.

Converting to Backless Booster Mode

If you’d like your Nautilus to be in no back booster mode, simply leave the back off at this point and reattach the fabric loops at the base of the cover behind the seat.

1. Tuck the seat pad in between the gap of the back support and seat area of the booster seat.  You’ll see 2 elastic straps showing at the rear of the seat.  Attach those 2 elastic straps from the seat pad onto the hooks on the rear of the seat.

2. Pull the elastic straps on the seat pad through the vehicle belt guide on the side of seat and attach to the hooks.  Then, repeat on other side .  You’ll now have a high-back booster that’s ready to ride!

Lower Anchors: Booster Mode

The lower anchors can be used to secure the Nautilus in the car while in high-back booster mode.

Fit to Child: Booster Mode

5 years old

Graco Nautilus: 5 years, 4 months old, 44 pounds, 45 inches

Graco Nautilus: 5 years, 4 months old, 44 pounds, 45 inches

Here’s our model from earlier, she’s 5 years, 4 months old, stands 44 inches tall and weighs 45 pounds.  This was her maiden voyage in booster mode!  The open shoulder belt guides made setting the seat up for her a snap.  Like so many combination seats, accessing the belt guides was much easier once the headrest was above the shell of the seat, confirming that making the switch to booster mode is best started when the child has outgrown the combination seat in harnessed mode first.  Otherwise, the headrest would be below the shell, making the shoulder belt guide hard to access.

 

Apparently, all the times I’ve reminded her sister to sit properly paid off because more than once, I heard her gasp because she’d started to slouch a bit, then she would remember to sit in an upright position.  She’s not quite ready for full-time booster use but with this seat, she’s got all of the help she needs to start the process.

The Safety Surround headwings absolutely helped with reminding her to sit properly.  In my opinion, and for my youngest kiddo, the Nautilus with Safety Surround would be an excellent option for booster training!

 

8 years old

Graco Nautilus, booster mode: 8 years old, 55 pounds, 50 inches tall

Graco Nautilus, booster mode: 8 years old, 55 pounds, 50 inches tall

At 8 years, 10 months old, 55 pounds and 50 inches tall, this model is at the top end of the size range for the Nautilus in high-back booster mode.  It still provides an excellent belt fit — the shoulder belt sits squarely across her shoulder, and the lap belt is on her upper thighs.

She reports that while the padding is comfortable behind her, the sides and headwings made her feel a bit cramped in the seat, at least in high-back mode.

 

Fit to Child: No Back Booster Mode

Graco Nautilus: 8 years, 10 months old, 55 pounds, 50 inches tall

Graco Nautilus: 8 years, 10 months old, 55 pounds, 50 inches tall

Here we see the our same 8-year-old, 55 pound and 50 inches tall model from the high-back booster section.  She’s much more comfortable using the Nautilus in no back mode.  The belt fit across her shoulders and across her lap is excellent and she also enjoyed the cubbies/cupholder!

Manual Storage — The manual stores in a handy compartment on the bottom of the seat.  Just tuck your manual into the slot and it will stay with your seat in case you need it during your travels.

Overall Thoughts

The Nautilus is a mainstay of the combination seat category — and with good reason!  It fits children of most body types and sizes well, in both harnessed and booster mode.  The Safety Surround padding on the headrest plus open shoulder belt guides made it an excellent option for both booster training and extended booster use for older Littles.

Coming in at a reasonable price point, the Nautilus has a lot to offer.  We issue a small word of caution that it’s not compatible in harnessed mode in every seating position we tried, but it was compatible with every other position in every other car, so it’s a safe bet that the Nautilus would work well in most cars.

Graco advertises that the forward facing Nautilus is the last car seat a child needs and we’d have to concur. Once your Little has outgrown their convertible car seat in rear facing mode, the Nautilus is an excellent option to take them to the very end of their car seat-using days!
