Moreover, I will also be responding to the queries related to the Nuna AACE Booster Car Seat Review in order to help you clear your doubts before you make a purchase.

Does it make sense?

So, without any further ado, let’s begin…

It goes without saying that the NUNA AACE is an impressive booster seat that is equipped with a wide range of comfort and safety options including optional recline and armrests.

Not only does it provide you with a secure fit but also possesses a hassle-free installation process.

This booster seat will last your child from around 4 years of age (40 pounds, 38 inches) to 8 years and beyond (120 pounds, 60 inches)

The fact that this unique booster seat can transition from a high-back booster to a backless booster enhances its duration of use.

Whether you’re a first-time buyer or an experienced professional, the piece of information that we’re gonna share with you in a while will definitely help you to understand the product better and also explore the hidden side of it.

Height & Weight Limits

The Nuna AACE booster seat operates in two modes, that is, high back booster, and backless booster.

In high-back booster mode, the car seat is capable of accommodating children weighing 40 to 110 pounds and 38 to 60 inches tall.

Your kid should be at least 4 years of age in order to reap the benefits of the Nuna AACE Booster seat.

On the other hand, in the backless booster mode, it can accommodate children weighing 50 to 120 pounds and 38 to 60 inches tall.

And, in order to begin using backless booster mode, your kid should be at least 5 years of age.

The good thing about this booster seat is that your child can use it for a longer duration.

In most of the cases, we found kids in the age group of 4 to 8 years were comfortable using it.


Well, let’s have a look at some of the idiosyncratic features that put the Nuna AACE Booster car seat in a different league altogether.

3D Growth System

Frankly speaking, the 3D Growth System is definitely one such feature that will catch your eyeballs.

The 3D Growth System enhances the seat’s lifespan as it accommodates your growing child in three different ways – height, width, and depth.

The first dimension of the 3D growth system is height.

Moreover, the seat is highly flexible and the headrest can move upward as your child grows taller.

It comes with 9 different height options.

Another parameter is the width.

The shoulder wings expand outward as soon as you raise the headrest.

Lastly, we’ve depth which can be increased by shifting the seat base forward or backward.

There are three possible depth settings that provide additional thigh support to your growing ones.

Ease of Use

Whether you’re a first-time buyer or an experienced professional, adjusting your seat in any of the three growth options would be a hassle-free experience.

The Nuna AACE Booster car seat is so easy to operate that the 9-position headrest can be adjusted with one hand.

The best part is, that the shoulder system works in conjunction with the headrest, and as the height increases, the unit will expand outward.

Even though you’re a first-time buyer, you wouldn’t be having any problem transitioning the seat to any of the three depth options.

And, when it’s time for your kid to start using the backless mode, the seat back lifts completely away in one swift movement.

Furthermore, the installation process is simple, easy, and less time-consuming as well.

Colored and guided belt paths reduce the risk of installation error.

In order to inform you of the secured latch, the universal anchorage system connectors have color indicators.

On top of it, in order to make attachments both customizable and safe, you’ve got a choice of installation either in the form of a lower latch connector or the vehicle’s lap-shoulder belt.

Can Serve Two Purposes

Needless to say, there is a tangible amount of time between when your child outgrows their forward-facing seat and when they are ready for a lap-shoulder belt.

Well, many forward-facing seats can be used until your child weighs 60 pounds with quite a few going up to 90 pounds.

Furthermore, you can’t use a lap-shoulder belt until your child has reached the minimum requirement of age and height.

The minimum age requirement is 8 years and the minimum height requirement is 4 feet 9 inches.

Most importantly, you’ll have to install a booster seat for your kid when he has exceeded 60 pounds in weight and is greater than 1 inch below the seat height.

I highly recommend the Nuna AACE Booster car because this little beast is capable of providing service to your kids when they have reached the 8-year age mark.

It is a 2-in-1 car seat – a high-back booster and a backless booster.

The back and headrest easily lift away, leaving a belt-positioning booster seat.

It makes the transitioning of your kid from a car seat to the vehicle’s lap’s shoulder belt system easy, effortless, and hassle-free.

Why Should I Buy Nuna AACE Booster Seat?

Frankly speaking, I can’t tell you whether you should buy a Nuna AACE Booster or NOT.

However, I can help you make an informed buying decision by highlighting some of the mind-boggling features that the booster seat comes with.

Safe Guided Installation

The Nuna AACE comes with a newbie-friendly installation process.

In any mode, the installation process will not trouble you at all as lower anchors are simple to attach and tighten.

Moreover, the seat includes UAS connectors, which stand for a universal anchorage system, that works perfectly fine with almost all vehicles.

And, the best part is, you can also secure a seat via the vehicle’s lap-shoulder belt.

What actually belt positioner does is guide the shoulder belt into the proper position.

Many of you wouldn’t be aware of the fact that in both modes, the guided belt path is colored and clearly labeled, and as a result, decreases the chance of user error.

Finally, side impact protection (SIP) goes over and above in meeting crash protection requirements.

I hope now you can understand that the ease of achieving a secure install makes switching vehicles headache-free.

And, the booster seat safety features mean no matter which car a child is riding in, parents can rest assured that their child is safe and secured.

Adjustable Features

The seat comprises comfort features that offer an 8-position recline, even with the lower anchors attached.

You’ll find built-in armrests in both the modes – high back, and backless.

Furthermore, you’ll also have a dishwasher-safe cup holder present next to the armrests which is easily accessible.

The good thing about this car seat is, that as you adjust the seat headrest, the padded shoulder wings will also adjust saving you both time and money.

In order to give your kid more room, they will automatically move outward, interesting, isn’t it?

In simple words, the adjustable depth feature helps to support growing legs.

In fact, each component results in a spacious seat for your kid.

Even though you’re going for an outing or trekking, the breathable fabrics and included ventilation panel will make the seat cool by preventing heat buildup and allowing proper air circulation.


If you’re a working mom like me then definitely, the Nuna ACCE Booster car seat can be a boon for you.

The car seat is easily installable and one-handed adjustments are straightforward to use.

As they work in conjunction with each other you don’t have to perform multiple actions.

Booster car seat fabrics are machine washable, and as a result, you can save time.

The removable cup holder is dishwasher safe which is definitely something to brag about.

Things That We Didn’t Like About NUNA AACE Booster Seat – MUST READ

Enough of bragging and boasting about the Nuna AACE Booster car seats.

Like any other product in the world, it also comes with its own sets of pros and cons.

The review wouldn’t have been unbiased if we hadn’t talked about the CONS of the Nuna AACE Booster car seat.

Bulkier and Heavier

Yes, you heard it, RIGHT.

The Nuna AACE Booster car seat is bulkier and heavier.

Everyone appreciates the idiosyncratic comfort features that the Nuna AACE Booster comes with, and the probability is very high that it will grab your eyeballs as well.

However, the drawback of the comfort feature is that it makes your seat a bit bulkier and heavier.

If I’m not wrong, in its highest position, it has a height of 33 inches, a width of 22.5 inches, and a length of 15 inches.

To be honest features such as shoulder supports, side-impact pods, and armrests are meant to add bulk.

With a weight of 15.6 pounds, the Nuna AACE booster car seat can be crowned as one of the heaviest booster seats on the market.

When you remove the back, the seat will become narrower and lighter.

Your kid can use it in the backless booster mode ONLY when your child fits the height, weight, and age recommendations.


Don’t wanna discourage you but it’s the fact that if you’re on a shoestring budget it would be difficult for you to afford this luxurious yet expensive car seat.

However, the price tag is justified seeing the kind of features that the car seat is equipped with.

It’s an investment that can pay you in the long run.

Harness Booster vs. Belt-Positioning Booster

Many first-time buyers wouldn’t be aware of the fact that Nuna AACE is a belt-positioning booster seat.

So, what does it actually mean?

In simple words, Nuna AACE doesn’t use a 5-point harness system but rather relies on the vehicle’s lap-shoulder belt to restrain your child.

However, a 5-point harness system is regarded as the safest restraint type for young children.

As per the recommendation from AAP, a 5-point harness should be used until the age of at least 5.

A transition from a harness to a high back booster should ONLY be done if your child is mature enough to maintain proper posture and meets the seat’s height and weight limits.

And, this maturity is achieved in most children between the ages of 5 to 7 years.

As most forward-facing car seats accommodate children up to 60 pounds your child should easily reach this benchmark before making a switch to a booster car seat.

And, trust me, once your child is ready, the Nuna AACE is definitely one of the safest booster seats that I’ve come across in recent years.

Definitely, the NUNA AACE Booster car seat will help you to achieve a perfect position across your child’s shoulder, chest, and lap.

NUNA AACE Booster Seat Alternative

In case, you’re not satisfied with the NUNA AACE Booster car seat and looking for an alternative, then definitely, you can definitely opt for an Uppababy ALTA belt-positioning highback booster seat.

The Uppababy ALTA belt-positioning highback booster seat is almost similar to NUNA AACE.

Essential and must-have features such as impact protection, a cup holder, and armrests are included in both the car seats.

Needless to say, Nuna AACE is more expensive but the price is justified seeing the increased longevity and more options that it comes with.

The ALTA has 7 possible headrest heights compared to AACE 9.

Moreover, the ALTA doesn’t offer any recline position.

Not to forget, the AACE can become a backless booster while the ALTA can’t.

So, it’s totally up to you to choose between the NUNA AACE and ALTA.

It’s A Wrap

First and foremost, I would like to thank you for being with us till the end.

Secondly, I would like to bring to your notice that I along with my core team have put loads and loads of effort into coming up with this idiosyncratic piece of information.

And, in case, you liked our efforts then please share the information with like-minded people and the ones who are in need of it.

After all, sharing is caring, isn’t it?

To cut a long long story short, the NUNA AACE Car seat is one of the best and safest seats that I’ve come across in recent times.

Not only does NUNA AACE offers working mom a sense of belonging, safety, and security but also ease of use.

We’ve emphasized time and again that the NUNA AACE Booster car seats are equipped with many convenience and expansion features to keep your children comfortable until they are at least 8 years of age.

In simple words, your kid can use a NUNA AACE Booster seat for years to come.

To be honest, it isn’t easy to find a car seat that grows with your child in depth, height, and width.

Not to forget, that a booster seat that reclines is also rare to find.

It goes without saying that the aforementioned unique features put the NUNA AACE Booster car seat in a different league altogether.

I’ll accept that the car seat is pricey but you need to also understand that it is a top-of-line booster with a longer lifespan and unique features making it a “value for money” investment that will pay you off in the long run for sure.

That’s all, as of now :):)
