My kid's infant car seat was a click 'n go bassinet with a soft fabric liner. His convertible car seat stays in the car, but it still reclines better than any adult seat, with more plush padding than the car itself. He actually prefers the car over the bed for naps. Only problem is that he's still rear-facing and his legs are getting a bit too long for the seat, but he solves that by putting his feet up.
Kid stuff is one area where I've been pleasantly surprised by how technology advanced when I wasn't looking. Car seats, strollers, baby gates, and toys are all way more advanced (and cheaper, inflation-adjusted) than they were in the 80s.
My main gripe about the car seat is all the damn waste. We have four of them and you can't sell them or even give them away. I'm not sure about the recycling situation yet, but even in the best case not much can be recycled.
My opinion is that it's way overblown, how many people have a serious crash with kids in the car? How many of them would then go on to resell the car seat? How many of those people would go on to have another serious crash to test the theory?
That said, when it comes to protecting our children, it's hard to justify saving a few bucks.
