The base for the Primo Viaggio 4-35 is equipped with the “Right Tight
System,” which easily and securely locks the base in place for added
stability with either the UAS strap or the vehicle seat belt. The base
has colour coded belt paths, which act as a guide for the vehicle seat
belt routing. A modern design with a rounded-shape 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.
