Nuna AACE Booster Car Seat

It's streamlined, custom-able and as beautiful as a booster seat gets. AACE grows comfortably with your child and even converts to a no back booster seat. It also exceeds American safety standards--the only thing about it that's overdone.  

Join the grow-volution.  


  • one-hand, 9 position height adjustable headrest
  • shoulder system works simultaneously with the headrest, expanding out while growing up
  • seat sports 3 depths giving growing legs plenty of support and space
  • converts from a high back to a no back booster car seat
  • energy absorbing foam and SIP pods take side impact security to the next level
  • lower anchor connectors allow for 8 position recline in high back mode & easily secure car seat to vehicle seat during use or transport
  • belt position-er aids in correct shoulder belt routing and minimizes user error
  • colored belt path indicators help decrease risk of user error
  • ventilation panels within the shell and breathable (and washable!) knit fabric create a comfy climate for even the longest of trips

Every little detail:

    I went from a pipa, to a rava, and now an aace. I've had a great experience with NUNA products. The safety features, quality, and the support is amazing.

    This Nuna AACE Booster Car Seat is fabulous! It's so easy to install. I like the fact that it can adapt to your child’s size and needs. I got the seat in Caviar. Although it was a little pricey, I am so glad i purchased it!
