PIPA. RAVA. AACE. The gangs all here!

You’ve probably heard of [or used] the Nuna PIPA, then the Nuna RAVA, and rounding out the Nuna family of car seats is the AACE Booster Seat. If you are shopping for a booster seat, then your little one's car seat days will soon be gone so you’ll want to make sure that you choose a booster seat that will actually last them until the end of their car seat career.

We love that the AACE can be modified to fit your growing child [comfortably] with its adjustable head rest, adjustable sides, adjustable seat, and more – bonus points that it can also morph into a backless booster – but we are getting ahead of ourselves.

Today we are sharing 3 features we love about the Nuna AACE Booster Seat.


  • High back booster: suitable for children 40 - 110 lbs. and 38" - 60" tall.
  • No back booster: suitable for children 50 - 120 lbs. and 38" - 60" tall.
  • Dimensions: 11.8" W x 14" D x 22.4" H
  • Weight: 16.4 lbs.

It Grows With Your Child

We listed the specs above for your convenience, but the AACE can be used from 40-120 lbs, or 60” tall. Let us do the math for you – that’s 5 feet. Some moms and Grandmas are 5 feet, so you know that you’ll definitely be able to use this seat for years! The 10-position adjustable headrest allows the seat to grow up – and grow out as the sides of this seat can expand in width to accommodate a bigger body. We love that this shoulder system works simultaneously with the headrest and is so simple to adjust as needed.

Extendable & Expandable Seat

We mentioned that the AACE has expandable sides, but you can even adjust the seat depth! There is a lever under the front of the seat that gives you 3 different depths to choose from to accommodate a bigger bum or growing legs. Plus, when the time comes the AACE can be converted to a backless booster – we love a good old 2-in-1.

Machine Washable Fabrics

All black [caviar] comfy cozy foam and fabrics will make your big kids feel like the pre-teen that they are with a sleek seat that looks like it is part of your vehicle. There are even ventilation panels within the shell to keep your rider cool!

The included clip-on cupholder is the cherry on top giving them a place to put their Frappuccino – your little one sure has come a long way from their rear-facing days! *cue the tears*

Safety in Every Stage

The AACE is made with energy-absorbing foam and side impact protection pods. We also love that it can be installed using UAS rigid latch [that fold into the base for simple storage] with red/green indicators.

Confident Cruising

What do you think of the AACE? Does it check all your boxes? It is wild to think that this really is the last car seat you will purchase for your child. Moving from a 5-point harness to a booster seat is a big deal so don’t try to make them grow up too fast! You'll want to check out our Booster Seats Tell All to ensure that your “mini-big-kid" really is ready to transition to a booster seat before you buy.

Happy shopping!
