All 15 infant seats were tested over a 5 month period side-by-side to fairly evaluate their performance in each rating metric. Each seat was used extensively by multiple testers and in multiple vehicles. We utilized four very different vehicle makes and models in our primary testing of installation and ease-of-use in an effort to get a general overall feel of functionality and features for installation purposes. Each seat was used according to the manufacturer manual.
At the outset of testing, we engaged with the National Highway Transportation Safety Administration (NHTSA) and a certified Child Passenger Safety (CPS) Technician to help us develop a set of comprehensive tests on infant car seats. As with all of our reviews, the car seat test plan and testing process was reviewed and overseen by Dr. Juliet Spurrier, our founder, mother of two, and a board-certified Pediatrician.
We researched and analyzed the crash test data in professionally prepared reports based on sled crash tests. BabyGearLab contracted with the same crash test facility used by NHTSA to perform crash tests on car seats in compliance with the same testing protocol used by NHTSA and under the FMVSS 213 standard. We combined our test data with crash test data obtained from NHTSA's own tests to create a comprehensive analysis of each seat.
Crash tests utilize a test dummy with G force sensors located at various points in the body. We analyzed the data and rated the seats in comparison with one another apples to apples. The more a seat exceeded the Federal safety standards, the better it scored in our analysis. It is important to keep in mind that all of the seats comply with Federal safety guidelines, but each seat responded differently in sled testing and resulted in scores that we believe can help differentiate one seat from another for the purposes of comparison.
