Light infant car seats

Hello! I am currently pregnant with our third baby pretty unexpectedly. I have hEDS and shortly before I found out I was pregnant I suffered two pretty severe shoulder dislocations that have left my shoulders pretty weak.

I’m super worried about lifting an infant car seat in and out of a car. Does anyone have experience with this or did anyone know any lighter car seats that will be easier for me to lift out of the car? I should be pretty okay with carrying them, but I’m super worried about the lifting part.
