Graco: Quattro Tour Deluxe Travel System
Of course you don't NEED to have a matching stroller/car seat combo. But, you do need to have a stroller that accepts your infant carrier. Not all stores have shopping carts that will hold your infant seat, so for many places, baby must be carried in a carrier, sling or infant car seat. Since most babies go to sleep in the car, it's a shame to wake them just to put them in a carrier or sling - it's much easier to leave them in the car seat and wheel them around. Plus, with the car seat attached, the two awnings meet and cover baby completely from sun, breezes, or light rain.
