Abstract
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.
