Trying to find the right booster seat for your growing child? You’re not alone! For many parents, the choice comes down to two popular models: Nuna AACE vs UPPAbaby ALTA. Today we’re sharing our insights on these two impressive options to help parents make an informed decision about which one may work best for their family.

UPPAbaby ALTA vs Nuna AACE Booster Seat Similarities

The UPPAbaby ALTA and Nuna AACE booster car seats share several common features. Both have adjustable headrests and side impact protection on the sides of the shell, with the AACE having side impact protection pods that can pop out. They both offer dual armrests to give little arms a break and a versatile cup holder that can be attached on either side. 

Design-wise, both booster seats have a sleek and modern appearance, enhanced by high-quality fabric that's not only comfortable but also easy to clean in the washing machine—a lifesaver for parents dealing with spills and messes. Installation is a breeze with both models featuring a rigid LATCH system that extends out the back, preventing it from becoming a dangerous projectile when not in use. Furthermore, both seats come equipped with well-marked shoulder and lap belt paths, making it simple to ensure our child is properly secured. It's reassuring to know that both of these boosters have gone the extra mile to prioritize safety during installation.

The height and weight requirements are also very similar for both seats. The ALTA is suitable for kids 38-57 inches tall and 40-100 pounds, while the AACE accommodates slightly larger children from 38-60 inches tall and 40-110 pounds.

UPPAbaby ALTA vs Nuna AACE Differences

While the UPPAbaby ALTA and Nuna AACE have a lot in common, there are some notable differences worth considering, mostly in the area of comfort adjustments. While both seats offer headrests with multiple positions, the Nuna AACE also features an adjustable shoulder area, a customizable 8-position recline in high-back mode, and a seat cushion with three depth settings, giving growing legs and shoulders plenty of support and space. The Nuna AACE also offers the option of converting from a high-back to a no-back booster once your child reaches 50-120 pounds. 

Price is another factor to consider. The UPPAbaby ALTA tends to be slightly more budget-friendly compared to the Nuna AACE. That said, it's essential to weigh this difference against the specific features and benefits that each seat offers when deciding which one is best for your family.
