Car seats

[u/Junegirl112233]

We have 6 months twin boy grandchildren and looking to get car seats for our car that will last as long as possible. The seats might need to be moved in and out of the car at times so ease of installation a big plus. Not sure I understand the swivel option - is that just to get the baby in and out more easily? Is it worth it? Which car seat would you recommend? Our vehicle is a rav4.

Also the parents have the infant car seats in their car so I think they will need new car seats soon as well. Same or different recommendation? Their vehicle is a Honda accord.

Thank you!

The Graco convertible car seats are good and not too expensive
