The Pinch Test for Harness Tightness
How do you know if your harness is tight enough? Give it the Pinch Test.
Your child won’t be safe in his carseat unless his harness is snug. The Pinch Test is the accepted method for testing harness tightness.
An outdated method for checking tightness is to stick a finger (or two) under the harness at the shoulder, but because we all have different finger sizes, it can lead to very a loose harness.
It’s never been acceptable to “pinch an inch” of harness for tightness.
