THE STROLLER The Z4 measures just 20 inches wide, perfect for adventures where space is at a premium. The streamlined design of the chassis makes maneuvering through crowds easier and more convenient. The telescoping handle accommodates users of different heights and the hand-sewn eco-leather bar adds a touch of elegance. The wheels have a suspension system and 12 ball bearings, which means they are 30% easier to push and can take on different surfaces. The Z4 chassis is travel-system compatible with the Primo Viaggio 4-35 Nido Car Seat (sold separately). The seat is detachable, reversible and can be folded right on the chassis. STREAMLINED DESIGN, EASY DRIVE The streamlined design of the Z4 allows it to be maneuvered with ease through heavy sidewalk traffic, narrow aisles, and crowded elevators. The hood is height adjustable and follows babyâ€™s growth while containing UPF 50+. Wheels with ball bearings and suspension allows for an effortless push, while easily overcoming bumps and uneven surfaces. The frame is composed of lacquered aluminum, which is very solid and sturdy, yet lightweight enough to be easily maneuvered and carried.
