Nuna Nuna - Aace Booster Seat 2019 / 2020

About the Nuna - Aace Booster Seat 2019 / 2020

Kids grow up so fast – but not fast enough to instantly go from a car seat to a safety belt, alas. A booster is a must for kids under 4’9”, ensuring that the safety belt is correctly positioned across their shoulder and hips to prevent injuries in the event of a collision. With the stylish and elegant Nuna Aace Booster Seat, it’s easier than ever to keep your kids safe in the car, and it’s designed to grow with your kid to adapt for perfect comfort!


The Nuna Aace features the new 3D Growth System, which grows in three ways with your child:


  • Growing up: The 9-position headrest can be adjusted with one hand;
  • Growing out: The shoulders of the seat expand simultaneously as you pull up the headrest, giving bigger kids more space on all sides;
  • Growing on: The seat has 3 depths, for custom support for growing legs.


Safety features on the Nuna Aace Booster Seat include:


  • Energy-absorbing foam and Side Impact Protection pods for side impact security;
  • A belt positioner to ensure that the shoulder belt is placed correctly;
  • Colored belt path indicators to decrease user error;
  • LATCH connectors to attach the seat firmly to the car, so it doesn’t become a projectile in the event of a collision.


Along with the 3D Growth System, the Aace pampers kids in the car with comfort features including an 8-position recline, ventilation panels, breathable fabrics, built-in armrests, and an included cupholder. The seat pad can be removed and machine-washed, to keep your Aace booster looking tidy and smelling fresh. While usage as a high-backed booster is the best way to take full advantage of the safety features of the Nuna Aace Booster Seat, you can also easily click off the top portion and use the booster without the back. This may come in handy for carpooling!


The Nuna Aace Booster Seat weighs 15.6 pounds, and can be used with the back installed for kids from 40-120 pounds and 38-60 inches, ages 4 and up. As a backless booster, it can be used from 50-120 pounds, 38-60 inches, and ages 5 and up.

In this video, Eli from Magic Beans introduces you to an exciting new safety advance from Nuna: the Nuna Aace Booster Seat! The Nuna Aace is designed to make it as easy as possible to keep your child safe in the car, and to customize the fit to your kid as they grow.


This terrific booster features the exclusive 3D Growth System, which lets you adjust all dimensions as kids grow up and out: when you raise the 9-position headrest, the shoulders of the seat automatically also expand! Plus, you can adjust the depth of the seat to provide proper support as your child’s legs get longer.


We recommend using a booster seat with a back, but the Nuna Aace Booster Seat can also serve as a backless booster when necessary, giving it yet another dimension that you can customize to fit your family.


Check out the video to learn more about why we love the Nuna Aace Booster Seat, and if you’re not sure if this is the booster for you, ask us! You can reach our baby gear experts at, or call us at 866-600-2326.
