Strollers weren't the only big story at the ABC Kids Expo this year. Car seats made a newsworthy appearance at the show, where one stroller company introduced its first car seat, a well-known car seat company unveiled its latest innovations, and a European company showcased its first foray into the US market.

Take a look at the latest innovations to come to car-seat design — we promise, you don't need an engineering degree to use them!
