Introducing the Nuna AACE booster car seat. Drum roll, please….It’s not just any booster car seat. It’s Nuna’s 2-in-1, high-back 3D Growth System booster, designed to grow with your child, just like your child grows. In fact, the AACE is coined the “grow-volution”, allowing us all to rethink the way a car seat grows with our child… You’ll be amazed to know that the AACE grows in three different ways:

• Grows up, with aone-hand, 9 position height-adjustable and comfortable headrest
• Grows out with ashoulder system that expands out while growing up, working simultaneously and harmoniously with the headrest
• Grown on with a baseseat that sports 3 varying depths, giving your precious one’s growing legs ample amount of space and support

And the 2-in-1 design of the AACE turns from a high-back booster to a no-back booster in a breeze!
