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 - 6 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 - 5 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 - 4 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?

    submitted byAnna - 3 months ago

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 - 8 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 - 8 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 - 3 months 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: Can you use a mat underneath the seat?

submitted by Nat - 9 days ago

  • A: Thanks for reaching out with this great question! You can use a mat underneath the seat as long as you're still able to achieve a secure installation that moves less than 1" front -to -back or side- to - side. We hope this helps! -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 - 2 months 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!

Q: What size cup will the cup holder fit?

submitted by CBK26 - 4 months ago

  • A: Thank you for your interest in the Nautilus® 2.0 LX 3‑in‑1 Harness Booster Car Seat. We don’t have a specific list of bottles or cups that fit in the cup holder, as sizes and shapes can vary widely between brands. The cup holder has an approximate diameter of 3.75 inches, which may help you determine whether your bottle or cup will fit. We hope this helps! - The Graco Team

Overall experience

[This review was collected as part of a promotion.] Installation was very easy. Besides following the instruction manual, there are also helpful installation videos available on YouTube. Overall, the car seat looks safe and comfortable. The fabric feels soft, although my niece tends to sweat easily, so it can get a little warm during the summer. However, with the air conditioning on, it hasn't been a major issue. Since this car seat doesn't have extremely deep side bolsters, I think it may be a better fit for slightly older children who prefer a roomier seat. A couple of things I wish could be improved: the side headrest padding feels a bit firm and doesn't have as much cushioning as I expected. Also, there are only two crotch buckle positions. Having one additional position would provide more flexibility. My 5-year-old niece is already using the outermost slot, and when she wears a fluffy dress, the buckle area can feel quite snug. She has occasionally mentioned that it feels a little tight and uncomfortable. That said, for this price point, I really appreciate that this is a 3-in-1 car seat with a steel-reinforced frame. The overall safety design gives me peace of mind, and I feel confident keep using it.

Still recommend but I HATE these cup holders

I love this car seat. BUT from day 1 if I would have known how horrible these cupholders are I wouldn't have gotten it. My son us autistic and he needs his cuphokders. They pop off so easily and he gets so mad and the soda or milk spills everywhere. I really like this carseat. Unfortunately im going to have to ask my dad to drill a hole from the cupholder into the booster seat part. Which I dont want to do since it will make it look ugly and im worried about the safety feature. I cant afford another carseat and its brand new. the 3 stars are directed towards the cupholders. If my son was a little more understanding then I wouldnt find the cupholders a problem. Since it is him, I am living in a little cupholder nightmare. 😅 Still recommend but I HATE these cupholders.

Hello. We appreciate the feedback. We DO NOT recommend drilling or altering the car seat in anyway as this can compromise the safety structure of the product. -The Graco Team

Awesome Seat!

[This review was collected as part of a promotion.] I bought the seat when my 3-year-old was ready to be forward facing. The seat she had was very difficult to strap her in and I didn't want to spend the rest of her time in a car seat fighting with buckles. This car seat was so easy to install, it doesn't take up too much space, she's super comfortable in it, and best of all she's easy to strap in. I loved this seat so much that I bought another one for the other car. Highly recommend!

Perfect for kids

[This review was collected as part of a promotion.] I bought this for my daughter who prefers stationary car seats over the swiveling ones. It was incredibly easy to install and is very solid and comfortable. It wasn't too expensive, either.

We love it! Super easy install!

[This review was collected as part of a promotion.] We moved to this when my kiddo moved to forward facing, as I didn't like the way our old seat installed forward. It was super easy to put together, and even easier to install! So easy, I uninstalled it and reinstalled it just to show my friend how easy it is! The harness moves super smooth, and adjusts nicely. My kiddo loves this seat. She's super excited that she has armrests like mommy. 100% recommend! Will be getting a second one when our next child moves to forward facing!

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.

It's great for larger kids. My grandson is 4 and 64 pounds and we're able to still use the harness. Love that it goes to 100 pounds. Good value

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.

Great car seat.

[This review was collected as part of a promotion.] Love this seat honestly I would have rated it five stars it’s versatile, my son says he is so comfy in it. It’s slim and fits well in all of our cars. Graco is one of the safest brands I know of and honestly installation is easy as can be. The only issue I had which took a star away we had a slight hole in the fabric upon arrival I don’t know if it got cut during production or what but the hassle of sending in all of the proof is more of a pain to me than having the tiny tear in it it’s just a bummer that it came like that.

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.

Nice looking, easy to install and use, lightweight

[This review was collected as part of a promotion.] This is a comfortable, sleek, safe high back booster seat for my growing kiddo - we already have 3 other carseats from Graco and this is the best looking one so far. We are moving her from the harness to the seatbelt and this made it so easy. When my younger one is forward facing, we will be happy to use this seat on him too!

Great Seat

[This review was collected as part of a promotion.] I really like this car seat, much lighter and more compact that the front-facing convertible it replaced, and leaves a ton more legroom for my son in my relatively compact car.
