Our Thoughts
When it comes to keeping your child both safe and comfortable during car journeys, the Nuna AACE and the UPPAbaby Alta booster seats are both strong contenders. Let's take a moment to highlight their key features and understand what sets these products apart.
First off, the Nuna AACE. There's a reason that this booster seat is perceived as premium. Considering its safety, adjustability, comfort, and practicality, it’s obvious why so many parents are fans. Its advanced side-impact protection, multiple recline options, breathable, washable fabric, and no added flame-retardant chemicals make this booster seat stand out from the crowd. It's also versatile, transitioning from a high-back to a no-back booster, catering to children of various ages and weights. The Nuna AACE offers room for growth without being overly bulky, a feature appreciated by many families. In terms of installation, the adjustable latch connectors and clear instructions make the process quite straightforward, allowing for minimal stress during setup.
On the other hand, we have the UPPAbaby Alta. This booster seat is celebrated for its emphasis on safety, proper belt positioning, and ease of use. Balancing comfort and essential safety features, the Alta makes car journeys comfortable for older kids. One of the standout features of this product is its rigid LATCH connectors for a secure, accurate installation. Additionally, it has an adjustable seven-position headrest, a built-in SecureFit belt routing system, and side impact protection pods, all of which contribute to the safety and comfort of your child. One additional attribute is the machine-washable seat pad, which simplifies the cleaning process—a definite plus for busy parents.
However, the weight limit for the UPPAbaby Alta is 100 pounds, while the Nuna AACE accommodates up to 120 pounds, making the latter a better option for prolonged use. Also, neither of these seats are FAA-approved, hence they might not be suitable for families who frequently take long-haul flights.
While both of these booster seats are excellent choices, I recommend the Nuna AACE if you're able to accommodate a higher price tag. With its impressive safety measures, ease of cleaning, added longevity due to higher weight limit, and its feature-rich design, this seat is well worth the investment. However, if you are seeking a comfortable booster seat with a unique rigid LATCH system for secure installation, and your child is within the weight limit, the UPPAbaby Alta is an equally good alternative.
