About

The Cosco Stack It! is part of the Car seat test program at Consumer Reports. In our lab tests, Booster seat models like the Stack It! are rated on multiple criteria, such as those listed below.

Booster fit (no-back): A rating that reflects a booster seat's ability to correctly position the lap and shoulder belts in various test vehicles using a child-sized dummy, when used as a backless booster. Additionally, it includes an assessment of the booster's compatibility with vehicle seats and interior components.

Ease of use: Our evaluation of how easy each seat is to use, including items such as the clarity of labels and instructions, the ease of achieving an appropriate belt fit, and the transition between highback and backless modes where applicable.
