ASTM F1566 Cornell Test, Firmness Retention and Surface Deformation Method

ASTM F1566 | Firmness Retention and Surface Deformation | Cornell Testing

In the mattress industry, the fundamental goal is to develop a mattress that will maintain quality and retain firmness over a long period of use. The Cornell Test within ASTM F1566 was created to measure two critical elements of a mattress, firmness retention and surface deformation, at various cycle points from 0 to 100,000 cycles in efforts to simulate mattress performance after approximately 10 years of use. 

ADMET’s H-Frame Cornell Mattress Tester is designed to perform the Cornell Test without the need for operator interaction. The system comes equipped with a specialized controller in which the user specifies the desired cycle points and initiates the test. The system then cycles between two forces per the specification, and automatically takes measurements at the specified cycle points. Upon test completion, a report displaying the force values at specified deflections for each cycle point is generated for calculation of surface deformation and firmness retention.
