Hello there,
I believe you want information on the Evenflo (not Everflow) Triumph. Looks like there is only one submission on this fit combination you can view
here.
All of the data we have has been submitted by people just like you. Anyone is welcome to submit their information on our form
here. Ultimately, all submissions are reviewed by one of our three staffed Certified Child Passenger Safety Technicians to try to ensure installations that are available for viewing in our database meed best practices for safety. (for example we would question a submission of a car seat installed in the front seat of a mini van). There are no restrictions on models of car seats or vehicles that are accepted into the database.
I hope that answers your questions.
Thanks!
