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.

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. Itís 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.

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.

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 itís time to get out! Itís given my big girl so much confidence and itís really great quality which is expected from this brand. We love it!
Safe, non-toxic Conversion Booster
By Nicole

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.
  • Safe, non-toxic, comfortable, sleek design
  • Snaps on bottom of sea cover often come undone especially with these seat extended.
  • Cupholder is too narrow to fit most reusable water bottles and comes out away from the seat easily.

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.

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 moneyís 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!
  • Easy to install.
  • Very soft fabric.
  • Rigid latch system for the win.

Pro's: Easy to install and no flame retardants
By Stacey

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!

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.

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

  • Comfy

  • 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

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!

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!!😍

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.

By Irina

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!!!

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.

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, 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.

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!
