Abstract
An overdeck assembly for use in a sofa bed mechanism consisting of a plurality of sections foldable between collapsed sofa positions in which sections are stacked vertically and extended bed positions in which the sections extend in substantially horizontal alignment. The overdeck assembly includes a flexible over deck member formed of a polypropylene sheet and secured to the sofa bed mechanism by a tensioning mechanism which allows the deck member to hang loosely below the sofa bed sections in the extended bed position of the mechanism and is stretched across the top of the stacked sections in the sofa position so as to provide a taut uninterrupted support surface for the sofa cushion or cushions.
