RESNA SS-1:2014

This standard applies to full body support surfaces (i.e., mattresses, mattress overlays, and integrated bed systems). Section 2 is intended to differentiate immersion characteristics. Sections 3 and 4 specify methods for the simultaneous measurement of the heat and water vapor dissipating properties of sleep support surfaces under test conditions that simulate body loading with flat and contoured profiles. These methods are intended to help differentiate performance characteristics of sleep support surfaces and are not intended for determining overall performance or for ranking or scoring of such surfaces.
