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

Good seat
April 30, 2021
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 didnít want to click together easily. When the seat belt locks when my child unbuckles, itís 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 canít easily get the belt around it, let alone my 6 year old trying to do it.
  • No smell
  • Easy to install
  • Looks nice

No fire retardants - yay!
April 26, 2021
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.
  • Free of fire retardants
  • Clips into the car
  • Uses car's seat belt
  • Cup holder could use more plastic and look like a full cup

This booster is incredible! Itís easy to use, looks nice, safe, and my daughter says itís really comfortable
  • Comfy
  • Looks nice
  • Easy to use
  • Narrow
  • Lots of adjustments to customize the fit
  • The latch system is terrible. It does not work for all vehicles including mine, so we have to buckle the seatbelt when it?s not in use which is annoying

Love this booster- bought 2!
April 10, 2021
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 didnít go with Maxi Cosi because their booster seemed so slender and didnít look comfortable! Britax fabrics are usually all so dark or girlie so didnít 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 heís more of an athletic build with broad shoulders. He and I appreciate how the seat widens as you raise the headrest. Heís a lot more comfortable in this seat, I highly recommend it for larger children.

Bought 2 of these as an upgrade to our Graco Forever seats for our 4 and 6 year olds. Those seats were falling apart, especially the fabric. These are amazing! So nice, plush and stylish and my girls love being able to do their own seatbelt. The covers wash easily and we just love them. We have the Rava for our baby so we are so excited to have 3 nice Nuna seats in our car!!😍

Stylish & Safe
January 31, 2021
My daughter was so excited to show her friends this ďfancyĒ car seat. Haha. Itís really chic! But more importantly, it is extremely safe. My only complaint is the width of the seat. Itís hard for my daughter to buckle her belt because the base of this car seat is wider than the last one we had. Check measurements.

We chose the Nuna AACE for our twins because they requested a booster with the side pillows around the head, which they were used to in their convertible seats. We also like that these can convert to backless boosters. At the lowest headrest heights we do find the shoulder belt sometimes does not automatically go taught, so we are careful to pay attention to the positioning before driving away.

Best booster I’ve come across !
December 16, 2020
My 6-year-old son uses the AACE and it's the most comfortable booster he's tried. The belt fit is excellent- the lap portion sits across his upper thigh/lower hip area and nowhere near his abdomen (which is good), and the sholder portion seems to stay right between his neck and edge of his sholder, never rubbing against his neck or sliding off his sholder. In other boosters he's tried he would often be wiggling around to get comfortable, but he seems to sit properly and relaxed for the entire trip in the AACE. The rigid lower anchors are a dream and the recline feature just puts this booster over the top, he can sleep comfortably and supported on longer trips- can't recommend the AACE enough!!!
By Elizabeth

After several research on the internet I arrived at this. It looks and feels so nice. I have a tall 2 year old and was looking for a perfect car seat that will grow with him and this is perfect. Safety wise I also feel like I got a lot of value for my moneyís worth. Itís definitely a purchase youíll never regret.

I am so happy I went with this booster. My daughter is just at 40lbs and I was really debating about what kind of booster to get her. I am so happy I went with the Aace. Itís super easy to install which is important for me because we fly a ton and are constantly on the go.

The quality and the materials are great. This seat like all other Nuna products is very luxurious.

The only thing I wish it had was a handle to carry it by and the cup holder isnít the most secure but overall itís a great seat.

Perfect Seat for Our Boys
July 22, 2020
We decided on the NUNA AACE car seats after a recent car accident. Our car seats needed to be replaced. During the accident our previous NUNA car seats where untouched. The ridge latch system and so many other factors made them easy to install and because of the breeze of installation, they were placed into our car properly. The comfort we have in knowing that despite our vehicle rolling twice, had the kids been in the vehicle theyíd like have been untouched allowed us to easily decide to continue with the NUNA brand for their added safety features as well as the fact that they are Green Guard Certified! The sleek look of them is certainly an added bonus.

Great car seat
June 21, 2020
Great car seat, very comfortable. Great quality as well. Not as strong/sturdy feeling as a Clek, but seems better quality than most manufacturers. Very adjustable and versatile. The only con, and this seems to be across all car seat manufacturers, is the seat belt is a pain when the car has a recessed belt buckle.
  • Great price
  • Great quality
  • Comfortable
  • Very adjustable
  • Buckle angle for recessed buckles.

Perfect for tall kids
June 15, 2020
My son is almost 5 and was telling me he felt squished in his Graco Nautilus. I could tell it wasn't the 5 point harness making him uncomfortable but the narrowness and depth of the seat. He's tall for his age and has a long legs and a long torso so I knew it was time to upgrade his carseat. I wanted something nice for my vehicle since I do pre-school drop off and pickups. And my vehicle also serves as the family vehicle on the weekends. I knew Albee Baby would have the best selection so it was a no brainer to order here. The adjustable seat depth and sides sold me. I let my son choose the color and he chose Aspen. I ordered on a Sunday and had it by Friday. Installation was quick and simple. It took me a minute to figure out that I needed to push the bottom seat back after clicking the latch bar in place for the seat back to sit flush with the vehicle seat. But that was the only hiccup I ran into. My son says he's much more comfortable and loves his new big boy car seat! And although the cup holder isn't what we're used to, I can appreciate that it's one less thing to clean!

I purchased this brand for my youngest son and when my older boy needed a new car seat it was a no brainer to get him a Nuva. My son loves feeling like a big boy and is very comfortable. I love how easy it was to secure to my car, how safe he is and that it grows with him so I wonít have to buy another car seat for him ever again!
  • Safe, comfortable, grows with him and easy to clean.
  • Wish had a better cup holder option

High Quality Booster Seat
March 28, 2020
We have a Rava that we love for our baby, and when we had to replace our high back booster after an accident, I did a ton of research. Ultimately, the AACE had the most of what we wanted. Installation was straightforward. The adjustable seat depth is a nice touch. The seat color is beautiful.

We bought 2 of these for our 8yr old as she wanted out of the 5 point harness seat. They arrived within 5 days and the packaging was fun! The seats were easy to assemble and fit into the car. We chose these not only because they stylish and comfortable, but also because the isofix bars lock into the seat making them very sturdy and safe.

November 19, 2019
We like this seat primarily for the fact that it grows upward / outward as the child grows and also has a removable back for when it's time for a backless-booster. Looks nice in the car and also seems sturdy as far as booster seats go! My daughter says it's comfortable to ride in as well.

The one "con" is that in my particular vehicle (2018 Lexus RX350) it's so difficult to buckle the seatbelt around the seat that my 5-year old cannot do it herself. And it takes some struggle for me to do it as an adult. *However,* I think this is almost all to do with how the seatbelts are configured (the insertion point is completely buried within the seat rather than having any of it above the cushion and it sits directly against the side of the booster) rather than the booster seat itself. I searched for a booster with a narrower footprint to see if that would mitigate the issue and could not find one.

This is exactly why we needed to transition from a convertible car seat to a booster. We love have loved Nuna since our Pipa and are so happy they offer this option for our child to grow.

Good but could be better

I like my Nuna booster, very nice and goods elegant. I gave four starts in stead of five only because the cup holder falls so easy and it is not stay with the booster. Very easy to get lost. So, this is a very good booster but can be better!

Great for a tall child
July 30, 2019
We purchased this for my over 4 feet tall 5 year old and it is large and accommodating. Overall it is great quality for a booster seat! I would say my only con is that it could use more padding for the actual seat. Thatís something I was desiring for the long car rides we take often.

Great quality, Comfortable, with some minor issues
March 12, 2019
This booster seat has excellent quality. My kids, 7 yo and 4 yo, said that the seats are really comfortable. It's also very easy to install. I especially like the design of the adjustable seat depth for growing legs. I haven't seen this feature in other booster seats. My only complain is that the Vehicle Shoulder Belt some times come out of the RED shoulder belt guide very easily. And my kids some times find it hard to place the lap seat belt under the armrest in order to reach the RED lower belt path. But I guess they could get used to doing it that way after doing many times. Overall, I'm satisfied with this product.
By Kevin
So far so good!

I just received the seat. The quality is looking fine. My child is liking the seat for the couple of times that the child has tried it. The fabric materials could be better.

Best Booster Seat!
March 3, 2019
My 6 yr old loves this booster seat! It is extremely comfortable for him and holds his head in the proper position well when he naps. The fabric is superior quality. The rigid latch is perfect and easily accessible. The seatbelt glides through the belt guide every single time; this was my top priority in my search for a booster seat. We were transitioning from a Britax Frontier CT because the seatbelt constantly got stuck/caught in the belt guide and therefore unsafe! No complaints whatsoever with the AACE! So glad we spent the money to get this booster!

Bought this for my almost 8 year old to replace his Britax Parkway SGL after a crash and wow what a difference. This seat is definitely worth the cost. Premium fabric, comfortable, easy to adjust and install, and it seems long lasting. I love that the seat adjusts out and the back gets wider as you adjust it taller. Nuna definitely thought of everything with this one.

January 13, 2019
This seat is very nice looking and has the safety features I was looking for (rigid latch and sip pods). I do wish the instruction manual was a bit clearer about a few things but thatís about my only complaint. I had to go the csftl website to clarify use of the of the sip pods and never did find a lot of info on the recline function of the seat. It has a decently high belt guide and fits my 9 year old daughter well.
