An innovative new category of car seat for preschoolers to preteens that’s safe and stylish.

About this Product
  • 40-120 lbs
  • High back or no back booster option
  • Expands in all directions to grow with your child


Car safety gets a lot of attention with younger kids, but the Nuna AACE solves for the years beyond that. This sleek and comfy seat grows as they do with a nine position height adjustable headrest, a shoulder system that works simultaneously with the headrest and a seat with three depths that gives growing legs plenty of support and space.

What makes it so safe? Energy absorbing foam and side impact protection pods. And it’s comfy too with eight recline positions. Ventilation panels within the shell pair with breathable, washable knit fabric to create a comfy ride.

The AACE securely attaches with lower anchors that work in your own car and when traveling. And fortunately for kids who may not love the idea of riding in a “car seat,” it feels more like a sleek chair with a seatbelt. There’s a belt positioner that helps with correct shoulder belt routing, along with colored belt path indicators.

The AACE converts from a high back booster (40 lbs to 110 lbs) to a no back booster (50 lbs to 120 lbs).


  • High back booster: 40 to 110 lbs, 38” to 60”, 4 years+

  • Overall seat dimensions (highest position): 33”H x 22.5”W x 15”L
