The Chicco KeyFit infant car seat made a splash when it hit the market, and now the company's NextFit Convertible ($280) is likely to do so, too. Inspired by the KeyFit's easy installation system, the NextFit uses a unique LATCH pulley system — called Super Cinch — to significantly reduce the effort needed to tighten the seat's LATCH straps. Suitable for kids from five to 65 pounds (and with a rear-facing weight limit of 40 pounds), the seat also features nine (yes, nine!) recline positions and a great leveling system so parents can easily tell if the seat is installed properly. Truly one of the easiest convertible car seats to install (so easy I could do it myself), the NextFit will be the must-have car seat when it arrives in stores in Spring 2013.
