The Nuna AACE Combination Booster Car Seat grows right along with your child from preschool to pre-teen. Its 2-in-1 design allows it to convert from a high-back booster to a no-back booster, while its 3D growth system allows it to expand up and out as your child grows.
The customizable side impact protection pods and belt-path indicators make riding super secure. Your child one will enjoy wearing a seatbelt just like you do. And you’ll be happy because you know they’re safe. And comfy. When they have an adjustable headrest, and an extendable, expandable seat with eight recline positions, how could they not be?

Nuna AACE
Had the Rava for my son and recently upgraded to the AACE. While the cup holder doesn't fit many of his cups the carseat is still a great choice. It was easy to install and he sits in it comfortably (4 years old).
