Product Description

The First Years launches a new convertible car seat, the True Fit SI which is easier to install, easier to use, safer for your baby. The SI has all the features of the original True Fit that make it so easy to use. The SI stands for Side Impact, and the new contoured head rest is designed for better head control. The contoured design helps in containing your child's head in the event of a crash. The harness is for use from 5 to 35 lbs rear facing and up to 65 lbs in forward facing installations.

Did you ever try to rethread a harness on a car seat? Ours is hassle free, the harness adjusts simply by moving the side adjusters and they are clearly labeled to help with the correct positioning. The C680 model features smaller bottom rails and the patented Rebound Energy Management system--a flip up rebound bar that actually helps manage the rebound in the unlikely event of a crash, pull the bar forward and it snaps in place with your rear facing installation and flip it back with you move to the forward facing installation. This seat is fully lined with EPP foam and has deep side wings that really surround your child. The larger interior dimensions keep your child comfortable as they grow. We have added a center angle indicator in the front of our seat for use when installing in the rear facing position. This easy to read indicator will help you determine if you have installed your seat correctly. For your infant, it will assist in achieving the recommended 45 degree angle for installation (without our head rest) and as you keep it rear facing to 35lbs (with the head rest) you can check for the recommended 35 degree installation angle.


  • The First Years True Fit SI Convertible Car Seat is side impact tested to international standards
  • Removable contoured head rest
  • Rebound Energy Management system and center angle indicator for rear facing installations
  • No rethread easy adjust harness
  • Two position recline and removable cup holder

      Comments about The First Years True Fit SI Convertible Car Seat - Black/Pink:

      Was close to impossible to get in the car and when rear facing, the straps and buttons that you need to adjust the straps and height are in the front of the seat, that is touching the back of the car seat..awful design. Do not recommend at all.
