Patent ID: 7681268

Claim:
A featherbed, comprising; upper and lower outer fabric layers, substantially identical in configuration and secured together along their respective longitudinal and end edges; a plurality of solid connections between the upper and lower layers, each connection having an undulating configuration from end-to-end thereof, in one direction of the featherbed and extending to opposing edges of said featherbed, thereby preventing communication between adjacent internal volumes between the solid connections, wherein the connections are spaced apart in the orthogonal dimension of the featherbed, wherein the connections are positioned in pairs having opposing undulating configurations, generally in the form of hourglass arrangements which include enlarged portions and narrow portions alternating along the length thereof, the enlarged portions being at least three times as wide as the narrow portions, wherein the narrow portions are at least 2½ inches wide to restrict migration of solid filling within the internal volumes while permitting loose solid filling to be blown in to fill the internal volumes; and loose solid filling positioned within the featherbed between the individual connections and the outer fabric layers.
