Car seat installation

Kayla
So we have had our car seat base in the car for a few weeks now but I started to question it the closer we are getting to actually having our baby. We have it set up in the middle using the seat belt instead of the latch system. Ive always heard middle is safer, but also heard latch system is recommended over the seat bet. I have looked over our car manual what seems like 100 times and it doesn't recommend one over the other. Help?!?!
