The Primo Viaggio 4-35 Lounge becomes a practical urban stroller when paired with a Vivace Chassis. Its more than just a car seat, with its easy fold, spacious basket, and comfort recline feature! The Primo Viaggio 4-35 Lounge on Wheels combines comfort and maneuverability for both baby and parent. The Primo Viaggio 4-35 Lounge car seat for babies features the Comfort Recline function: the backrest reclines and the leg rest extends, allowing the child to lie down in the best ergonomic position when used on a stroller. The extendable Pagoda Hood provides full coverage, shielding baby from outside elements. The base's Load Leg and Anti-Rebound Bar work together to increase stability and significantly reduce the risk of injury in case of an accident. The Kinetic Pods offer enhanced side impact protection: just a few of the innovative features that help protect your newborn. The Primo Viaggio 4-35 Lounge on Wheels 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 comfortable handle provides a centralized fold with a convenient one-handed opening and closing. The hand-sewn eco-leather bar adds a touch of elegance. The wheels have a suspension system and ball bearings, which means they are 30% easier to push and can take on different surfaces. The Primo Viaggio 4-35 Lounge on Wheels chassis is compatible with a reversible Vivace seat or bassinet (both sold separately). The seat is detachable, reversible and can be folded right on the chassis in either direction. The streamlined design of the Primo Viaggio 4-35 Lounge on Wheels allows it to be maneuvered with ease through heavy sidewalk traffic, narrow aisles, and crowded elevators. 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.
