How We Tested

How We Tested Car Seats for 3-4-Year-Olds
  • We recently tested several car seats suitable for children between the ages of three and four. 
  • Through our comprehensive testing process, we have identified the perfect seat that meets every safety requirement while being comfortable and fully adjustable.
  • We conducted extensive research on each seat to understand its features, performance, weight capacity, and overall fit in a vehicle. All seats were evaluated according to industry standards and guidelines from the American Academy of Pediatrics (AAP).
  • We put each seat through a series of rigorous tests to ensure it would provide maximum protection for 3-4-year-olds. 
  • This included crash testing with an impact sled simulator, which measured how well the seats managed forces generated in a real-life crash situation. Our experts also examined every strap and buckle for durability and strength.
  • In addition to evaluating crash test results, we looked at how easily each seat could be installed into cars. The seats were tested in vehicles from major manufacturers to ensure they fit correctly with all safety features working properly. 
  • We took notes on installation time, ease of use when adjusting straps or buckles, if any additional parts were required, etc.

Finally, when looking at the comfort levels of each car seat we considered padding materials used as well as overall design elements such as straps that wouldn’t constrict movement too much or become uncomfortable for long drives.

    Graco 4Ever DLX 4-in-1: Does the recline 1,2,3 for rear-facing have a weight restriction?

    1. Nicole Moore Avatar

      The Graco 4Ever DLX car seats come with a newborn- friendly design, allowing them to be used in any position and still providing optimal protection for your little one. We recommend having it reclined as far back into its seat belt harness strap notch possible so that there’s no strain on their neck when they’re sleeping or just sitting watching you drive off!

    Graco 4Ever DLX 4-in-1 secure when in rear-facing mode or does it slide side to side?

    1. Nicole Moore Avatar

      The Graco 4Ever DLX car seat is a breeze to install, and once you get the adjusting done there’s no movement whatsoever. I tried pushing from both sides – not only does this chair not budge; if anything my older grandson was able lean back more securely in his new high tech booster seat! The rear facing position feels very secure so until next time enjoy these seats while they last

    Does Chicco NextFit Zip fit in the Chicco travel system?

    Where is the strap release button for the Chicco NextFit Zip? Is it under the padding next to the belt?

    1. Nicole Moore Avatar

      Chicco has created a clever design feature with their NextFit Zip car seat. The release button for the Chicco’s Installation is hidden under its cover, and it can only be accessed by sticking your finger in between two slots which are very tight spaces that require some effort on behalf of an adult to push down onto them so they will pop open easily when released from their position being depressed against each other due either accidentally or upon intent- this would not bode well if there were smaller children around trying do something as advanced suchafely opening upgear gadgets!
