Searching for a Car seat for a Hyundai Sonata hybrid



I have a 2013 Hyundai Sonata that I need to fit 3 car seats in. My infant seat will have to go in the middle because of the design of the other two car seats I have. ( Diono radian 3xrt: they wobble in the middle seat and don’t feel secure) The problem is there is a hump in the middle but it’s an odd shaped hump. Anyway, I’m trying to figure out what car seat I should purchase for my new baby that will fit.
A picture can be seen here of the hump shape.

First, thanks for finding a picture so we don't have to go searching for one!

The good news is that infant seat bases are generally pretty narrow, so you have a pretty good chance of finding something that will work with the hump. Do you have a budget in mind? Do you expect your newborn to be especially large or small? These answers will help us tailor our answers to your needs.

Here are some recommended seats you can start looking at:

And here is the short version if you want one or two options for various price ranges:
