From the Manufacturer, Peg Perego:
Safety, Comfort and Style All in One!
Safety and design
The innovative and upscale shell design of the Primo Viaggio 4-35 Infant Car Seat with Base optimizes baby’s safety and comfort at any growth stage. Side Impact Protection (SIP) is adjustable to six different positions with no re-threading required to protect baby’s head and shoulders at any growth stage. An energy absorbing EPS lined shell enhances protection and is perforated to guarantee maximum air circulation. Dual Stage Cushion System includes two (2) cushions to properly position baby’s head and shoulders within the protected side wings.
Ease of use
The Primo Viaggio 4-35 Infant Car Seat with Base weighs 9.5 pounds, allowing easy portability from car to stroller. The patented handle design is short and compact, which makes it easier to move in and out of vehicle. Seat and handlebar have color coded belt paths to help in belt routing if base is not in use. The Primo Viaggio 4-35 can attach directly to any Peg Perego stroller (except for the Pliko Mini and Skate), without the need for adapters.
The base for the Primo Viaggio 4-35 Infant Car Seat is equipped with the “Right Tight System,” which easily and securely locks the base in place for added stability with either the Latch strap or the vehicle seat belt. The base has color coded belt paths, which act as a guide for the vehicle seat belt routing. A modern design with a scallop-shaped bottom allows for a better fit and is gentle on any vehicle upholstery. The Primo Viaggio 4-35 base includes a built-in anti-rebound bar for superior protection in the event of a collision.
