Unpleasant bouncing or other oscillations resulting from movements upon aqueous filled furniture or other apparatus, e.g., a water bed, is inhibited by filling the furniture with aqueous fluid and additionally a water soluble viscosity increasing agent. Other additives such as preservatives or algicides are preferably incorporated into the aqueous fluid. This increased viscosity imparts a dampening effect to water movement within the furniture for comfort of the user(s) and yet provides the uniform cushioned buoyancy attributable to conventional water filled furniture.
