Q: Can this car seat be rear facing for a baby that out grows a carrier car seat?

submitted by Lola - 2 years ago

  • A: No. It can only be forward facing.

    submitted byIce cream fiend - 2 years ago

  • A: No, you are looking for a convertible car seat. This car seat is good for ages 2+ since it is forward facing only.

    submitted byBrit - 4 months ago

  • A: Thanks for your interest in our Nautilus 2.0 LX 3-in-1! This model does not have a rear facing mode, only forward facing 5 point harness mode, forward facing highback booster mode, and forward facing backless booster mode. Thanks! - The Graco Team

Q: Does this have a back tether? I do not have latches in my car.

submitted by stephanie - 3 months ago

  • A: Thanks for your interest in our products! The Nautilus 2.0 LX 3-in-1 Harness Booster does not have a back tether. The car seat is installed using the seat belt.- Graco Team

    submitted byGraco Consumer Care - 3 months ago
    Brand expert

  • A: Not sure why Graco is misinforming customers, but I just bought and installed this- it absolutely DOES have a back tether! It does have the option to install with a seatbelt instead of their latch strap, it’s possible the Graco expert is trying to say that maybe the seatbelt installation might not require using the back tether?

Q: Does the cover come off in parts, in case there is a pee accident, can just the seat cover come off or does the whole seat cover need to be removed?

submitted by MSF - 6 months ago

  • A: Thanks for your interest in our products! The seat fabrics does come off as a separate part. We hope this helps! -Graco Team

    submitted byGraco Consumer Care - 6 months ago
    Brand expert

  • A: The seat cover has separate parts for the back and the bottom! But… the cover that would get peed on has loops that attach in the back of the car seat, so you’d have to unhook the entire seat to take the pad off

    submitted byAnna - 24 days ago

Q: What is the max height and weight for the 5 point harness?

submitted by Lexie - 1 year ago

  • A: Make sure to check the weight requirements of the latch system in your vehicle. It is usually 65 pounds but that includes the weight of the car seat .

    submitted byCustomer01 - 1 year ago

  • A: Thanks for your interest in our NAUTILUS 2.0 LX Harnessed Booster! The forward facing 5-point harness mode has a weight range from 26.5-65 lb, and the height limit is up to 49". Hopefully this helps! - The Graco Team

Q: Does this recline? Or is it in one seat position?

submitted by Nat - 7 days ago

  • A: Thank you for your interest in our products! The Nautilus 2.0 LX 3‑in‑1 Harness Booster Car Seat offers four seat recline positions. We hope this helps! - The Graco Team

Q: Does the entire seat cover remove for machine washing or is it only the seat pad [like the convertible car seats]?

submitted by Nat - 7 days ago

  • A: Thank you for your interest in our products! The fabric on the Nautilus 2.0 LX 3‑in‑1 Harness Booster Car Seat is machine washable. We recommend washing it in cold water with gentle soap on a delicate cycle, and allowing it to drip dry. Please do not use bleach. We hope this helps!

Uncomfortable

My 3 year old hates this car seat. He screams every time he wakes up from a nap because both of his legs are asleep. Switched to the graco extend2fit with no complaints.

Purchased late April 2024 and loved everything about it. Super easy to install and was comfortable for my kids. The only flaw I found was after 2 years the fabric on the seat is ripping apart.

Target Sucks

NEVER RECIEVED. Fighting for my money back as they delivered it to the wrong address because they put two shipping labels on one box. Absolutely terrible customer service and will never shop with Target again.

I had the original version of this seat and loved it. When I had a wreck I replaced it with this seat as well as my other child’s E2F. They changed something about them and the cup holders won’t stay on. They lock in but then my kids barely bump them and they are off. Sometimes just the cup being sat in them knocks them off. Otherwise i like them

Too wide fir Kia telluride.

Beware if you have a Kia telluride!!! Impossible to buckle the seatbelt independently when you transition to a Highback booster with how deep Kia's seatbelts are and how wide this seat is. Otherwise we love it. Just bummed it won't work for the telluride.

I had a Diono Rainier for my daughter that we used for four years. I liked it a lot (as I prefer the Diono brand). However, the seat did not fit well in the new vehicle we bought a few months ago. I needed a seat that would fit in the space better and not slide around as much. I have had Graco products in the past but never loved them. However, this seat is great! I love the size of it (it doesn’t take up as much front to back space in the seat) and the no-rethread harness is so convenient. I like that the frame is steel-reinforced (one of the pros of Diono seats) but it’s not heavy or cumbersome to move or install. It was very quick to install with the seatbelt. We are currently using it as a five-point harness but I think it will work well as a booster when she gets to that point. I don’t feel like it’s super padded but my daughter was very comfortable in it on our recent road trip from Texas to South Dakota. If you are looking for a combination seat, this should be on your list.

My little one is sitting very comfortably in this seat. The ease of them able to do their own seat belt as they are in the “I do it” stage gaining their independence. Our child is also tall and the seat belt length is great for their area vs our previous car seat which was too tight and not enough slack

Cup holders need to be revisited

It’s great other than the cup holders. And I realize 2 stars over cup holders sounds extreme but they pop off SO easily and are required for safe use of the car seat. It’s a really poor design choice to make something so poorly designed a part of the safety system in any way.

Recline is a plus

I love the recline feature, for me was a requirement due to head flop. Not too much padding but I rather prefer safe over padding on the seat. Recommended

Grest booster

This booster is very comfortable and well made. It’s easy to install and take out. And the materials feel like an upgraded version of the other Graco boosters.

Over priced annoyance.

I CANNOT stand this car seat! The cup holders CONSTANTLY fall off, it is very cheaply made for that high dollar price they want for it. The only thing I like about it is the color/fabric design and the 5 point harness as some little despite being 40 +lbs are shorter or just little and I don’t think mine was ready for just full booster and seatbelt. It has no LATCH system (I personally like) so it’s just a free range seat in the back sliding everywhere ending up on the floor. There is little to no padding for comfort so I have no clue how my child sat in that thing on a 10 hr road trip! Some like this and this brand but I can’t wrap my head around why?! I do wish I would have just stuck with the NUNA brand.

3-in-1 car seat

Love this car seat! From the padded seat to the best side head protection I’ve ever seen in a car seat, this car seat is very well-built. It also can be turned into a booster seat as your child grows.
