The Peg Perego Prima Pappa Diner is part of the High chair test program at Consumer Reports. In our lab tests, High chair models like the Prima Pappa Diner are rated on multiple criteria, such as those listed below.

Safety: Safety for each high chair was assessed by our testing, which is based on the currently-voluntary safety standard, ASTM F404-16. Tests include evaluations of the restraint system, stability of the high chair, and static and dynamic load assessments as well as other tests.

Ease of use: Ease of use is based on trained panelists' assessments of harness adjustment and use, folding and unfolding, removing and replacing the tray and tray insert (if any), adjusting seat back and height where applicable, removing and replacing the seat cover.

Ease of cleaning: Ease of cleaning reflects how easy or difficult it was to clean the high chair, taking into account the configuration and materials used in the chair frame, seat, seat pad, tray and tray insert, if any. Easiest-to-clean surfaces should be smooth with minimal seams or crevices to collect gunk. Seat pads, if present, should be machine washable and/or easy to clean effectively with a damp cloth or sponge.
