Nuna does it again. Top marks for this booster that grows in so many dimensions with your kiddo. I liked it so much I ended up getting two! Absolutely love it.

With using the LATCH system this seat is easy to install and my son likes how comfortable the seat is.

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.

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!

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. That’s something I was desiring for the long car rides we take often.

Bought for my 4yr old. Super easy to install, the head support when he falls asleep is AMAZING compared to other seats we’ve had. I love how when you adjust The height, the wit also adjust.

Very happy with this seat. My boy is comfortable in it and it's top-rated for safety. Also, incredibly quick and easy to install. Doesn't hurt that it's darn stylish too.

This booster seat gives me peace of mind... while making my seven year old enjoy being in it. It is so comfortable for him and when he falls asleep he says he loves that it has the pillows on the side of his head!

Nice seat but it’s really big and bulky compared to our Cybex Q2 Fix.

It was so easy to install. My 6 year old loves his new booster, especially the extra cushion near the head. I will definitely get another for my 4 year old when he gets older.

The seat is made of great quality materials and is very comfy. So far everything is perfect.

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.

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.

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!

Very sleek and sturdy! Love how the Nuna latch system make the booster more secured!

My husband and I didnt need to do much reasearch to buy this car seat we have been buying the Nuna products since my child was a baby. We really like the quality, it is comfortable and it is worth the price. The installation is easy ans very secure.

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.

Sleek design is both easy to install and comfortable for my son. It's a winner in every aspect.

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 that’s 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.

I really like this car seat a lot. I use it for my 4 year old. It looks very safe and it is easy to handle. The only thing I do t like, I had to wash the part where she sits on, and even though it says it is maschine washable it totally messed up the cushion inside. I had to open up the seam to make everything straight again. For a seat that is that price I expect it to be easier to wash.

The quality is amazing and the safety features Are such a great added.

nuna comes through once again with a great product. I love the duplicity if the design and function of this seat.

This Nuna AACE Bppster Car Seat (in slate) is fabulous. Easy to install. I like the fact that it can adapt to you child’s size and needs. Have only used for my granddaughter a few times so far, but exceeds my expectations. It is also beautiful. Although a little pricey, well worth it.

I did a lot of research on this car seat and the Nuna brand before buying. Nuna is one of the few car seat manufacturers that uses high quality materials not doused in chemicals. The seat fits my 8 year old son perfectly! His only complaint is his drink (a hydroflask) doesn’t fit in the cup holder.

Bought this for my petite 4 year old and this car seat will be the last one that we need to buy. The cushions are great material and comfortable for my little one. Also this car seat allows for a slight tilt for easy naps and holds my toddlers head up perfect. Love this seat.

Love this booster. My sons head no longer falls forward, it’s great!

Nuna always has quality products but you definitely pay for every penny. The thing I love about this car seat is how much detail they put into it. It took a while for my son to get use to having the actual seat belt across his chest but he loves how comfortable the car seat is and how "grown up" it makes him feel. Definitely recommend this.

I bought this booster seat in berry for my 6 year old daughter. I love the color and the design. My daughter loves it too and says it’s very comfortable. Great purchase overall.

We left our daughter pick her color when we were buying our new daughter's Nuna and she chose the Berry color. The red is beautiful and the seat is amazing. We have used the anchor system for reclining the seat on long car trips and the normal attachment for the upright position and both are super comfortable for her. We love the safety of Nuna.

We love Nuna brand! This booster seat is a great addition to our van along with the Maxi Cosi 85 for our 4 years old and 2 years old. Our son loves how comfortable it is and we love how trendy and sturdy it is. Thank you!

I love the color booster for my 6 years old son, very sturdy & nice. He seem to like sitting on it for a long ride. Booster very compact & doesn't take too much room. I would definitely recommend this booster for anyone who's looking to buy a booster out there .

This booster seat is made so well. They really thought of everything. My toddler can sleep comfortable on long car rides and I highly recommend this seat to anyone shopping for that next step seat.

Bought this chair for our son. We like the minimal design that blends with our car interior. Its easy to install, comfortable for our son, great construction quality/ very sturdy yet light enough to move from car to car. The only thing that isn't perfect is the fabric doesn't "breathe" and can be a bit hot for a child who falls asleep in the chair and/or spends a lot of time in the chair on a car trip etc. Overall though we are very happy. We owned a Diono previously and like this chair better.

Recently purchased this seat for my son who has outgrown a 5 point harness, and he is loving it! He tells me how comfy it is and how much he loves his upgrade! I am impressed how easy it was to install and how nice the fabric is! It seems very durable which is great for how rough my boys can be and also very safe. I would definitely recommend to any family looking to move there child into something bigger, who can get in and out on there own!

Very happy with our purchase! Needed a high back booster for my six year old son and for once I don't have to argue with him to sit in it.. he loves it! The material is so soft and the head cushion is perfect for when he falls asleep in the car. The actual car seat is large and still has a lot of room for him to grow with it. Easy to instal and easy to wipe down clean. But my favorite part of all is that the seat stays in place while I'm driving with the seat anchors!

Great quality super easy to install I just took one star because of the arm's rest is too short, it is useless unless it is on backless mode, My kid says he is comfortable.

Awesome design and my daughter loves it. Quick and easy to install in the car.

Purchased this for our 5 year old. It's very well made and easy to put use. The overall design is solid.

Excellent quality, sturdy and well built. Easy to install and very comfortable. My five year old daughter loves it. Definitely recommend!

One of few car seats that actually look good. Great quality and design. Only issue I have is the cup holder could be bigger or even better if it was adjustable. Other than that it is awesome.

Easy to install and super comfy for my big, 6 year old. Love the recline feature and feels so much more sturdy than other brand boosters! Would definitely purchase again!

Seems sturdy and safe. It came with accessories that you may end up needing to make it fit correctly in your car. Looks good and sleek... still takes up a lot of space though. All in all we like it.

This booster has many adjustments for comfort and safety. It is also very attractive.

I ordered this for my almost 5 year old. He looks so comfortable and doesnt complain anymore! Love the color and style and most importantly that it will grow with my son.

So far, so great- we love this booster seat. Our 4 year old (almost 5 year old) weighs in at about 48 lbs, making this seat a great option for him. We have the Nuna convertible seat also, which is great for the earlier stages. I thoroughly researched seats and was between this and the Clek Foonf. Ultimately, I decided to go with this one based safety ratings and looks.

I bought this car seat for my daughter (age 6) and it is amazing! Very sturdy, high quality and most importantly, she doesn't complain about it. I feel great knowing she is in a high back booster and the wrap around style still gives her plenty of room! Additional "growing" features are great! I could not recommend this seat enough!

I always like to use something for a few weeks before I attempt to tell anyone how great it is. I am a mom of 3 and a certified foster home, so trust me when I say I've seen my fair share of car seats + boosters! This particular one is super easy to assemble, even if you are outnumbered by tiny humans and running on tiny energy fumes. You just snap the two pieces together, and bam. Done. Installation is also idiot proof. Give the booster one good push and you're golden. Also, removing the booster to transfer from car-to-car is as simple as pressing in two buttons and pulling the booster out. As far as being comfortable, my 4 year old falls asleep in this thing almost every time he's in it. And, it is, by far, the most padded booster (and maybe even car seat) I've ever felt. We have two Clek's and one Evenflo at the current moment, and this is squishier than ALL three. The seatbelt guide is a nice feature, as is the cupholder. The fabric REALLY does wick away heat! We live in Vegas, so I can definitely say that with confidence. Aside from all of that, the side/neck/head coverage is amazing and I feel really good about my little guy being in it! His head DOES NOT slump forward, not ever, not even once. We have an Infiniti JX35 and a Nissan Rogue, and his head doesn't slump when this seat is installed in either vehicle, regardless of the recline of the seat. We love this thing, and so does the little guy. Highly, highly recommend.

Excellent carseat! My daughter is comfortable, safe, its attractive and it will grow with her for many years to come.
