GRACO QUATTRO TOUR DUO all the way! It is my 3rd double stroller that I have owned and is by far my VERY favorite! It is a tandem stroller, but the the front seat holds a child up to 50 lbs and comes with seperate snack and cup holders that allow an older child easy access in and out when they are to that point. My middle son is now 3 and likes to walk in the mall a lot, but gets tired. He can get in and out at will, or at my will I can strap him in and he stays put. It manovers awesome and is my very favorite piece of equipment. I would say it should most likely accept your infant seat because it should stay put by the snack tray, but I would bring your seat to the store and try it out just to be sure. Hope this helps.
