BODY SUPPORT FOR BED OF SEAT Abstract A body support for a bed or a seat having a plurality of resilient support members or springs that are movable between a retracted or collapsed, inoper- ative position and an extended, operative position. The springs are contained in a case of flexible sheet material so that when the springs are collapsed, the case is collapsed or depressed into a relatively thin layer for storage or other purposes; and when the springs are extended the case will be distended by the springs to provide a resilient support such as a mattress, "box-spring" or a combination thereof for use in a bed or seat. Actuating means is provided for actuating one or more of the springs between the retracted and extended positions thereof, and connect- ing means interconnects all of the springs to drive them from the retracted to extended positions. The body support is especially suited to sofa beds or other foldable bed or seat structures because, in this application, the folding parts of the latter structures are coordinated with the body such that when the bed is folded into the storage position, the springs will' simultaneously be moved to their collapsed position contracting the surrounding case into a relatively thin layer, thus enabling the body support to be stored within the confines of the associated structure. Conversely, when the sofa bed is unfolded to form a bed, the springs will move to their extended position to provide resilient support.
