The recovery characteristic of a seat cushion indicates the ability of the cushion to return to its pre-loaded shape and dimensions following a period of loading.


Why this test is needed

The recover of a surface is associated with repeated loading of the cushion and may be indicative of fatigue of the surface.

How this test is performed

 A loaded indenter is applied to the surface and the height is measured at various intervals. Test report includes the average original thickness of the Cushion at the IT location and the average ratio of the of the recovery thickness to the original thickness at 25s and 1200 s intervals.
