There is disclosed a substantially completely stable damped liquid displacement support system (11) which comprises an envelope of liquid impervious flexible material having panels (13) and (15) and provided with a valve (17), at least one interior divider (19) provided with a plurality of openings (25) and (27) disposed across the interior of the envelope separating the envelope into at least two compartments (21) and (23), each compartment containing a core (29) of resilient liquid absorbent material and a liquid substantially saturating the core. The opening (25) and (27) permit the liquid to migrate between the compartments (21) and (23) when pressure is applied to the system.

A damped liquid displacement support system which is substantially completely stable with respect to wave action or rolling motion of the liquid contained therein and nonsusceptible to the accumulation of a substantial amount of said liquid in a particular portion thereof when force is applied there

A damped liquid displacement support system which is substantially completely stable with respect to wave action or rolling motion of the liquid contained therein and nonsusceptible to the accumulation of a substantial amount of said liquid in a particular portion thereof when force is applied thereto, irrespective of the spatial disposition of said system, said support system comprising an envelope of flexible liquid impervious material, said envelope having two substantially parallel panels of substantially the same size, each panel having a border surface, said border surfaces of said panels being sealed together in a liquid impervious seam, one of said panels serving as a body supporting surface, a core of resilient liquid-absorbent material occupying substantially all the space within said envelope, a liquid substantially saturating said core, a valve mounted in said envelope for communication between the interior thereof and its ambience for admitting and discharging liquids and gases, and at least one interior divider substantially parallel to and the same size as each of said envelope panels and separating said envelope into at least two compartments each of which contains its own liquid-saturated core, said interior divider having a plurality of peripherally disposed openings and no other holes therethrough, said openings in the periphery of said interior divider being located and sized so as to cause said liquid to migrate between the compartments of said envelope in a controlled substantially uniform flow with substantially no wave action or rolling motion and without accumulation of a substantial amount of said liquid in a particular portion of said envelope when pressure is applied to said envelope having a force component perpendicular to said body supporting surface, irrespective of the spatial disposition of said system, whereby an individual may use said envelope as a support cushion, said liquid within said envelope gradually seeking equilibrium about that portion of the individual\s body contacting said envelope.
