2020 Nuna AACE Booster Car Seat


The Nuna AACE grows with your child during the pivotal transition from pre-schooler to pre-teen, starting as a high-back booster and converting to a backless booster for big-kid status.

The AACE allows your child to grow up and out, thanks to its 3-position seat depth and 9-position adjustable headrest that simultaneously expands the shoulder area, too.

Energy-absorbing foam with side-impact protection pods provide top protection, while the belt positioner and color-coded indicators minimize the possibility of user error.

New for 2020, the AACE is fire resistant without the use of any flame retardant chemicals, from the fabric to the foam used in this booster car seat. The AACE meets the standards for Greenguard Gold certification, which means it has been thoroughly tested and certified to not contribute VOC's, or hazardous chemicals, into the air your child breathes.

The Nuna AACE helps keep your child comfortable on long car rides, thanks to 8 recline positions in high-back mode, an included cup holder, breathable and washable fabrics, and ventilation panels inside the shell of the seat.
