What Infant Car Seat Latch System Is Best For You?

Little Canadian offers a vast selection of Infant car seats, each with its own unique features and installation methods, however, choosing from this selection can be difficult. A feature that may heavily factor into any parent’s choice, is the ease of installation. Infant car seats offer three types of installation, rigid latch hooks, soft latch hooks, and a hybrid of the two. These latches are a part of the Universal Anchorage System, UAS for short. Cars manufactured after 2002 should have these in the rear passenger side and driver side, with few having a UAS in the center seat. Cars without the UAS are still able to carry infant car seats, but they must be secured with a seat belt instead.
