Our Thoughts
The Diono Radian 3RXT Safe+ and the Safety 1st Grow and Go All-in-One are two high-performing car seats designed to grow with your child. The Diono Radian is particularly well-suited for families with multiple children, as its slim design allows for fitting three car seats across in most vehicles, while the Safety 1st Grow and Go is a budget-friendly option that still offers a combination of safety, comfort, and convenience.
When it comes to safety, the Diono Radian stands out with its steel-reinforced frame and EPS foam for side-impact protection. The Safety 1st Grow and Go, although it meets all safety standards, has had some users report challenges with installation and strap tangling that could potentially compromise safety. Additionally, the Diono Radian holds a weight advantage across all configurations. With a maximum weight limit of 120 pounds in booster mode, compared to the Safety 1st Grow and Go’s 100 pounds, it ensures longer utility for your growing child. Notwithstanding, both car seats are FAA-approved for both rear and forward-facing configurations, enhancing their adaptability for travel.
User convenience is another significant consideration. While both car seats boast machine-washable covers, users of the Diono Radian have found the reassembly particularly challenging. On the other hand, the Safety 1st Grow and Go scores points for not only a machine-washable cover but also being dryer safe – a thoughtful feature for busy parents.
Balancing the characteristics of both car seats, the Diono Radian 3RXT Safe+ is for parents prioritizing top-tier safety and long-term usability, and particularly for those with more than one child in a car seat. However, if budget is a crucial deciding factor, the Safety 1st Grow and Go All-in-One is a worthy consideration with its compatibility across multiple growth stages and convenient maintenance features. Keep in mind, though, to ensure a secure fit during installation as some users reported challenges in this area. Install the car seats correctly every time to guarantee your child's safety.
