The Peg Perego Pliko P3 Stroller and the Primo Viaggio car seat are the two components that form a complete travel system. Alone, the Pliko P3 is fully loaded. Brakes, four wheel suspension, and swiveling wheels create a smooth ride. The five point harness supports and restrains your child and the front bar doubles as a tray for toys or snacks. There are a few notable features in addition to all of the standard ones.
