Abstract
An elevation structure system possesses anti-decubitus ulcer characteristics, and may cooperate with a mattress overlay also having anti-decubitus ulcer capabilities as part of a mattress overlay system, in which multiple elongate, positionally adjustable, relatively moveable risers are configured for selective placement in conditions of transverse, subposed, under engagement with the sides of an overlay to create substantially non-inclined, elevated, depth-supplemented regions at locations along the length of the overlay. The evelation structure and overlay may each include a dynamic-response core expanse formed of an open-cell, compressible viscoelastic foam coated with elastomeric, moisture- and gas-flow-managing, differential-thickness coating structure load-transmissively bonded to the entirety of the outside of said core expanse to function as a dynamically-responsive unit therewith.
