Horizontal Stiffness

Why this test is needed

This test shows the change in force over time in response to a displacement, or how hard a cushion pushes on the tissue following a change in position.

How this test is performed

A loaded buttock shaped indenter is applied to the support surface and is pulled laterally and the force is measured.
