Mattress overlay system with positionally adjustable, lateral ramp-wedge bolster structure

摘要: A bolster structure system possesses anti-decubitus ulcer characteristics, and may cooperate with a mattress overlay also having and-decubitus capabilities as part of system, in which multiple elongate, positionally adjustable, relatively moveable bolsters are configured for selective placement conditions lateral under-engagement the sides an to create inclined, side elevations these at locations along length overlay. The each include dynamic-response core expanse formed open-cell, compressible viscoelastic foam coated elastomeric, moisture- gas-flow-managing, differential-thickness coating load-transmissively bonded entirety outside said function dynamically-responsive unit therewith.
