my favorite car seat

After extensive research, I purchased the Nuna AACE for my 5yo, who is in the 95th percentile for height. What I like: - tall 5yo is very comfortable in it, as is my petite 8yo. - It will fit both of them for a long time (big reason for splurging for this seat) - the seat pan can be lengthened as they grow, not just the shoulder space and head rest. - rigid latch, and comes with latch guides - in our car, the LATCH bars are difficult to reach and the guides are VERY helpful! - flame-retardant free fabric - seat belt is a good fit on both kids (and is rated best bet for belt fit in any car by the IIHS) - can be used without a vehicle headrest - can be reclined for comfort when sleeping (not just vehicle seat fit) - when my 5yo has fallen asleep in it, the seat keeps him upright and belt path remains optimal What I don't love but aren't deal-breakers: - upper seatbelt guide could be tighter/harder to undo - in our car at least, the belt gets twisted and comes out when unbuckled with almost every ride - rigid latch is rigid, but has a hinge that makes it slightly less easy to line up with LATCH than our other boosters - no metal in the frame (I know this is isn't necessary and asking for it is probably overkill, but it would still make me feel better!) - the headrest connection has a lot of give when extended. While the manual states that the AACE can be used without a vehicle headrest (another reason I got it - our old car does not have them in the back seat), it doesn't feel sturdy to me without something behind it. That being said, though I haven't found *the* perfect booster yet for my family, I like the AACE better than the other two seats we have, which are Peg Perego Flex (for travel) and Clek Oobr. In the Flex, both kids say because the headrest is so thick, it pushes their heads forward, though it's great for folding up and taking on a plane (it has to be checked but at least isn't an oversized item), and should still adjust to fit my tall kid for a long time. The main complaint with the Oobr is the short seat pan - for both kids, almost 3-4" of their thighs are unsupported by the seat in high-back mode, and they tend to scoot their bottoms forward from the seat back to compensate. Once they're old enough to ride backless, it shouldn't be a problem, but that's a long time to go with a less than ideal fit.

Easy to install and lightweight.

3rd nuna car seat. Can’t go wrong with them. We Love them

Our favorite booster seat. My girls reached the height restriction on their 5 point and we wanted to keep them safe and secure still. This is the perfect option. Easy to use and comfy for my girls!

Another great product from Nuna. We have brought our kids up with Pipa, Rava, and now the Aace. We love the functionality., looks, and of course safety that Nuna provides. Very happy with this booster!

Best booster seat ever! Nuna is my go to brand!

We used Clek car seats and were really sold on staying with Clek for our booster upgrade, until I heard they were uncomfortable. That really stuck with us, and we started researching other options. We came down to the Nuna AACE and the UPPA Alta. We chose Nuna for a few reasons -- comfort, head support, quality, and the ability to convert it to a non-back booster when the time comes. The uppa option did not have the 2-in-1 feature and while it cost less, it meant having to buy a 3rd seat down the line which didn't make sense for our family. The Nuna installed easily, the quality is evident, the "grow with me" feature is awesome and my kiddo says it's comfortable. He does feel like the arm rests make it harder to buckle the seat, and he's pretty skinny so the fact that you have to grow it width wise when you raise it doesn't really help him. Only other "complaint" is that the cup holder is SMALL. It fits a standard kids water bottle (thermos funtainer) but does not fit wider bottles (like a yeti/hydro/etc), so we're trying to find an adapter.

We just converted our 2 boys over to the booster seats. We purchased 2 to try them out and the boys love them. I love that these booster seat are secured into the seat. My 5 year old has no problem buckling himself in and getting out when he needs to.

Awesome seat! Very comfy, love it!

We transitioned from the Nuna Rava carseat to the booster. Easy to install, sturdy, comfortable, and looks great. The way the cupholder attaches to the seat is a little flimsy. Other than that, can't complain!

such a great purchase

This is our 4th nuna car seat purchase and I couldn’t be more pleased. Easy to use and setup, will definitely be ordering a second one for our other car.

My child loves it! Comfortable.

My very favorite booster seat. Easiest installation & love that it goes from high back to backless booster. Bonus that it looks SO good!

We chose this seat mainly for the flame retardant-free fabric. The fact that it is very comfortable, easy to use for our 5-year-old and the fact that it reclines with the seat at all huge bonuses. She loves her seat. The install was easy also.

Wonderful booster option for my 6 year old. We love Nuna, so we decided to try the booster and it’s love, just like our other seats.

I bought two of this car seat already. I also own the Nuna convertible car seat which is heavier than this one. This nuna car seat is very easy to assemble. This is minimal design car seat and I love all the the colors. It’s also lighter than the other nuna car seats so removing this car seat and transfer from car to car is just as easy. I like how this is a 2 in 1 car seat and comes with a cup holder.

I enjoy Nuna baby products, including their stroller, baby/toddler car seat, and this booster car seat. My child can easily take a nap in this comfortable booster car seat. I feel it is pretty safe as well. Definitely recommended.

Easy to install and lightweight. Comfortable and easy to use. Love the cup holder.

Super easy to install and looks so nice! As usual Albee baby online is easy to buy from with fast shipping!

Love how compact this seat is but the bottom seat cover constantly gets pulled off. It is worse when used as a stand alone booster vs. high back booster.

My sons been using this for close to 2 years now and we love it. The latch feature is great and held strong in our recent accident. Install is great and my 10 year old says it’s very comfortable compared to his cheap booster in my other car.

We love all things Nuna, so it only made sense to upgrade our oldest to the next lineup of car seats in their product family. My oldest is 5, and she loves the independence of this car seat. She gets right in and buckles herself. And also unbuckles herself when it’s time to get out! It’s given my big girl so much confidence and it’s really great quality which is expected from this brand. We love it!

My son was so happy to be out of a five point harness! The seat is safe, well-built and we are very happy with it! My only two complaints are that the snaps often come undone on the bottom of the seat cover and I wish the cupholder was built-in instead of removable.

We bought this for my 42in tall 5 year old! We take long trips often and our old booster seat lacked the padding and comfort our AACE does! We bought a nuna baby seat when she was born and I should've known better and purchased the AACE the first time around when shopping for a booster. Love the reclining feature and that the width of the seat increases and the headrest setting gets higher.

Great booster seat. I feel so safe with my kids in it after attaching it, it wont even budge.

One of only 2 boosters on the market that is free of fire retardant. We love this high back booster that grows with our child. Easy to adjust with a rigid latch. Cant beat the safety, design, and comfort!

I don't have much to compare this to. But after my son grew out of his Nuna Rava, I read and watched tons of online reviews and decided this would be a good next step. I really like it and my son does as well. I bought the black one. It looks great, very simple. It does not visually scream "kid seat," which I prefer. The way it latches into my car is so easy it's amazing compared to the Rava. It takes maybe 10 seconds to remove or install. It's on the large side. I wouldn't want to carry it around too much. But swapping into the other car is easy breezy. Most importantly it feels very solid, safe and well built. Small gripes: 1) the seatbelt pops out of the little internal hook and I have to rethread it. Not a big deal, but a little annoying. 2) When there is no one in the seat, it rattles over bumps and such. It's not loud and it's not bad, but the Rava never did that. But then again that seat took time and muscle to get it properly loaded up. I imagine most people wouldn't notice it. My wife doesn't. But being somewhat "sound sensitive," I have noticed. 3) The beverage holder only holds beverages, and only of the right size. His previous one he could put in hot wheels or whatever else he wanted. This was a disappointment to the little dude. The AACE is built like a tank, latches very easily and very solidly, my son is very comfortable in it, and it looks terrific.

I bought 2 of these Nuna AACE Boosters for my grand kids that grew out of their regular carseats. The kids love how cushioned and comfortable they are compared to their other booster seats. They are a little heavier than most but you can feel how much better they are made. These boosters are pricey but well worth it for the quality.

Nuna makes great products with great features that are easy to use. These booster seats are no exception. Everything adjusts to grow with your child. This booster seat is more expensive, but you get your money’s worth with the adjustability, comfort, and overall ease of use! The quality, engineering, and customer support make Nuna the best car seat manufacturer in my opinion.

Easy and secure install! We love our nuna rava seats, so going with another nuna was a no brainer for us. Material is great! I think it will be very easy to clean. Lots of extra features for a booster. And love that rigid latch to help ease my mind from a five point to booster transition. Albee baby shipping was very quick as it has always been in the past. Thank you so much!

The only reason this seat didn't get a 5 star was because the cup holders are very small. We use the kids size Hydro Flask and it won't fit.

We got this item for our second vehicle and it’s amazing as the rava I can’t wait to transition my other two kids to these.

Beautiful and functional. I love all the nuna products, definitely a luxury appearing brand.

When I started my search for a new booster seat I was important to me to find a company who values health and safety - the AACE is a safe, and easy to install booster while also being without toxic flame retardants. Over the next few years, my son will be spending a lot of time in this seat and so I definitely want to limit any exposure to toxic chemicals if I can help it.

I purchased this after buying a Nuna Pipa for my youngest, and what sold me was the ease of installation... There's NOTHING like it. A quick push and it locks into place, or a simple push off the buttons and it's out... No more breaking my fingers trying to teach into the latch. Three natural is really nice and wipes easily, and we loved that the seat depth is adjustable for kiddos with long legs. I'll forever be a Nuna fan after this!

This seat has fit our needs perfectly. It’s sturdy, comfortable and very adjustable! I have tried quite a few other seats, and hope we can use this one until the end!

Was fairly easy to put together. You have to lay the upright part flat on the ground then fold it into the bottom seat. Was a little tough to do and felt I was going to break the hooks, they didn’t want to click together easily. When the seat belt locks when my child unbuckles, it’s tough to get it back far enough into the seat belt return area to unlock it, the wing of the headrest gets in the way and I can’t easily get the belt around it, let alone my 6 year old trying to do it.

Love this new booster - very happy that it was possible to finally find a fire-retardant-free booster for my kid. It does not have its own seat belt system - have to use the car's seat belt, which can be cumbersome for mom to clip in and un-clip. Glad that it came with a cup holder, although they really saved on plastic there - would be better if it was fully cup-like and could double as little toy/mitten storage. These are minor compared to the health benefit of fewer chemicals.

This booster is incredible! It’s easy to use, looks nice, safe, and my daughter says it’s really comfortable

This booster has been in our lives for 5 years and still going strong!

I researched many boosters! I Love Britain and Maxi Cosi brand! We had the Britax infant then when needed to upgrade we needed a convertible car seat with light breathable fabric for our southeast Texas weather and Maxi Cosi pria max sand was just what we needed! Looked at Britax and Maxi Cosi for a booster seat but ultimately landed with Nuna! Love the attention to detail of this car seat and width which is why I didn’t go with Maxi Cosi because their booster seemed so slender and didn’t look comfortable! Britax fabrics are usually all so dark or girlie so didn’t choose one of them. This Nuna booster is made very well and easy to clean!

My son is a big 7 year old, he weighs 70lbs but he’s more of an athletic build with broad shoulders. He and I appreciate how the seat widens as you raise the headrest. He’s a lot more comfortable in this seat, I highly recommend it for larger children.
