Give your big kid a booster that’s as comfortable as it is safe. The Nuna AACE is a luxury high-back booster with Nuna’s 3D growth™ system—so it fine-tunes to your child for an exceptional fit on every trip. Raise the 9-position headrest, the shoulder wings expand automatically for more room, and the seat base offers 3 depth settings to support growing legs. On longer drives, the multi-position recline (when anchored with the lower anchors) helps kids relax and stay properly positioned.

Parents love how easy it is to secure: use the vehicle seat belt for the child and attach the booster to the lower anchors for added stability (or install without anchors if the car doesn’t have them). Plush, FR-free fabrics and energy-absorbing side-impact protection round out a premium ride that pairs beautifully with your other Nuna gear.
