Our Thoughts

When it comes to car seat options for your child, there are two strong contenders: the Diono Radian 3R and the Nuna AACE. Each seat comes with its own set of strengths and unique features, making the decision one that should hinge on your individual needs as a family.

The Diono Radian 3R is a convertible car seat renowned for its slim profile and robust build. It can handle different seating positions: rear-facing, forward-facing, and as a high-back booster. This versatile seat is loved not only for its functional flexibility, but also for its ability to fit three across in most vehicles. This is due to its narrow design, making it a dream come true for families with smaller cars or multiple children. It offers a sturdy steel frame construction and memory foam padding, adding to both safety and comfort. Additionally, it accomodates children upto 100 pounds in the booster mode and upto 65 pounds in the forward-facing configuration. It is also FAA- approved for both forward and rear-facing modes. However, some points to consider are its weight and some difficulty in installation in smaller cars. There have also been reports about difficulty with removing and cleaning the cover.

The Nuna AACE, on the other hand, transitions from a high-back booster to a no-back booster, ideal for children over 4 years old and boasts a slightly higher maximum weight limit of 120 pounds in the no-back booster configuration. It shines for its commitment to safety with features like its SIP side-impact protection pods and energy-absorbing foam. Parents will appreciate its machine washable fabric and simple disassembly for cleaning. It does fall slightly behind the Diono in terms of versatility, as it does not offer the convenience of being used in a rear-facing position. However, it makes up for this with its sleek modern design and commitment to comfort.

In essence, choosing between these two will come down to what is most crucial for you as parents. If you are looking for a long-term investment, with a car seat that will adjust with your child as they grow, and especially if you have multiple children or a smaller car, the Diono Radian 3R might be your best bet. However, if you place more importance on a higher weight limit, resounding safety features, and a sleek design, and are willing to spend a little more, the Nuna AACE may better suit your needs. Regardless of your choice, both options prioritize your child’s safety and comfort, promising a safe journey for the little ones.
