Potential Drawbacks

Weight and Dimensions

The Safety 1st Grow and Go 3-in-1 Convertible Car Seat is one of the lightest seats in the group, weighing 16 pounds. This makes it a convenient option for grandparents or as a spare seat. The seat is somewhat wide, measuring 18.7 inches at its widest point, which is slightly above the average for convertible car seats

Installation and Ease of Use

Installing the Safety 1st Grow and Go using the LATCH system can be challenging. The seat features hook-style LATCH connectors, a line level decal, and no lock-off mechanism, making it difficult to secure the seat properly. Additionally, the recline adjustment handle design is similar to other seats that did not score well, and the strap threading area is congested. It would be beneficial to have color coding or other indicators to help with installation, but the seat's black design requires careful attention to the manual.

Crash Test Performance

The Safety 1st Grow and Go 3-in-1 Convertible Car Seat has a slightly above-average crash test analysis result. While it meets federal guidelines, its performance is not exceptional compared to other seats in the market. The HIC sensor recorded higher than average results, which negatively impacted the overall score. However, the chest clip sensor showed fewer G-forces, indicating impressive performance in this area.
