  • Failed two major safety tests: The sides are too low and the seat moved too far when pushed sideways and forwards.

How we test

There is no Australian and New Zealand standard for portable seats, so we base our testing on some relevant parts of the AS/NZS 2195:1999 standard for high chairs, with a few other tests specific to portable seats.

Major failures include risk of a fall due to insufficient side and rear barriers, choking hazards from easily removed small pieces, insecure attachment to a chair or table and a harness that allows a child to stand up. Minor failures include less serious examples of major failure conditions, plus limb/finger entrapment hazards.

We also check the stability of the portable seat. If it fits to a table or chair, we check how securely it attaches and that it doesn’t move too much when pushed forwards or sideways. And if it can be used as a floor-seat, we check it doesn’t tip over.

We won’t recommend a portable seat if it has a major safety failure.
