Nuna AACE Booster Car Seats

The Nuna AACE is a 2-in-1 belt-positioning booster seat that converts from a high back booster to a no back booster. It is designed for children from 40 to 120 lbs. The AACE features a unique 3D growth™ system, adjustable side impact protection, and a LATCH system that allows for 8 recline positions. Built with flame-retardant-free materials, it is the ideal choice for parents seeking a long-term, comfortable, and easy-to-use booster for their growing child.

Why Parents and Kids Love the AACE

The transition from a convertible car seat is a major milestone. Your child wants to feel independent, and you want to know they're safe. The Nuna AACE is engineered to satisfy both needs. It's a seat that respects your child's growing desire for autonomy while delivering the uncompromising safety and quality you expect from Nuna. As one parent told us, her daughter calls it "her throne."

A Seat That Grows in Three Dimensions

Kids don't just grow up; they grow out. The AACE is designed with this reality in mind. Its 3D growth™ system is awesome:

  • Grow Up: The one-hand, 9-position headrest adjusts effortlessly for height.
  • Grow Out: The shoulder system expands outward simultaneously with the headrest, giving them more room instead of feeling squeezed.
  • Grow On: The seat base has 3 depths, extending to provide plenty of support for growing legs on long trips.
End the Car Ride Complaints

An uncomfortable child can make any trip feel longer. The AACE tackles comfort head-on. Ventilation panels built into the shell and breathable, washable knit fabric create a comfortable climate, even on hot South Carolina summer days. With eight recline positions (in high back mode), your child can nap comfortably without the dreaded head slump.

Fostering Independence, One "Click" at a Time

"I can do it myself!" The AACE is designed to empower your child. The colored belt path indicators and open design make it easy for kids to learn how to route the seat belt correctly. As one parent of a sensory-sensitive child told us, the independence of buckling himself in was a "game changer" that made car rides far more pleasant.

Engineered for Safety

Nuna's design philosophy puts safety first, using smart, practical features that make a real difference.

  • Side-Impact Protection: The AACE features energy-absorbing EPP foam and adjustable SIP (Side Impact Protection) pods. These pods attach to the side of the seat facing the vehicle door, creating an additional crumple zone that absorbs impact forces before they reach your child.
  • Secure LATCH Installation: The AACE's lower anchor connectors (LATCH system) are a key feature. They secure the booster seat directly to the vehicle's frame, which does two things: It keeps the seat stable and prevents it from becoming a projectile in a crash when your child is not in it. It allows for the multi-position recline, providing stability even when the seat is angled back for sleeping.
  • Healthy Materials: From the fabric to the foam, every element in the Nuna AACE is sourced to be flame resistant without any added fire-retardant chemicals. It is also GREENGUARD Gold Certified, meaning it's tested for over 10,000 chemicals and proven to have low VOC emissions, contributing to healthier air inside your car.

Nuna AACE: Frequently Asked Questions

Q: What is the difference between the Nuna AACE and the AACE LX?
A: The AACE LX is a newer, more premium version. The primary differences are that the LX has a magnetic buckle holder, additional ventilation, and comes with two cup holders instead of one. The core safety and 3D growth™ features are very similar.

Q: Can you recline the Nuna AACE?
A: Yes, the AACE has 8 recline positions when used as a high back booster and secured with the vehicle's lower LATCH anchors. This is a standout feature not found on many boosters.

Q: How do you clean the Nuna AACE?
A: The micro-knit fabric seat cover is easily removable and machine washable on a delicate cycle (use cold water and lay flat to dry). The plastic components and cup holder can be hand-washed.

Q: When should my child switch from high back to no back booster mode?
A: A child should use the high back booster for as long as possible, as it provides crucial side impact and head protection. You should only switch to the backless booster when your child has outgrown the height or weight limits of the high back mode (110 lbs or 57 in), and their ears are above the top of the headrest at its highest setting.

Q: How long is the Nuna AACE good for before it expires?
A: The Nuna AACE has a lifespan of 10 years from the date of manufacture. You can find the manufacture date on a sticker located on the bottom of the seat.
