Our Thoughts

Delving into two different but highly recommended car seat options, the Graco Nautilus 65 3-in-1 and the UPPAbaby Alta highlight a multitude of features any parent would appreciate.

The Graco Nautilus 65 gets its name from the 3-in-1 functionality it offers as it can transition from a forward-facing harness seat for toddlers to a highback booster and then to a backless booster seat as your child ages. Not just versatile, Nautilus 65 also puts safety at the forefront with the 5-point harness system and a reinforced steel frame. The durability and robust design mean it could potentially be the only car seat you'll have to purchase, handling weights from 22 to 100 pounds. The forward-facing seat supports children up to 65 pounds which offers more extended usage compared to other models. However, some parents have reported that the installation can be tricky, and there are some minor challenges with the buckle's adjustability.

On the other hand, we have the UPPAbaby Alta primarily designed as a high-back booster for children between 5-10 years old, with weight ranging from 40-100 lbs and a standing height of 38-57 inches. Its main advantage is the simplicity of installation thanks to its rigid LATCH system, and the overall ease of use makes it quite user-friendly. Additionally, parents have noted that the spacious design and thick padding make long travels more comfortable for their children. However, a potential setback would be the issue with the shoulder belt, as it tends to slip out of position frequently.

Both car seats have their distinct strengths. The Graco Nautilus 65 offers incredible durability and versatility as it's appropriate for various stages of your child's growth. It's a notable safety contender, making it worth the slightly higher price point. The UPPAbaby Alta, while solely a high-back booster, scores major points for its emphasis on comfort and straightforward installation.

If you're looking for a long-term investment that has the option to transition with your child's growth, then the Graco Nautilus 65 3-in-1 could be the ideal choice for you. However, if immediate comfort, easy installation, and seat cushion maintenance are your top priorities for an older child, then you can't go wrong with UPPAbaby Alta. It would be worth noting that while the Graco Nautilus 65 has FAA approval for usage in Forward-facing mode, the UPPAbaby Alta lacks this particular clearance. This might impact your decision if frequent air travel is a factor.
