Abstract: A floor-supported sofa frame has a bolster support back adjoined with end walls which are further interconnected by a crossplate enclosing an area containing a cushion support member spaced above the floor. The space between the cushion support member and the floor defines a storage area wherein a floor-supported trundle bed is removably housed for withdrawal to form a lateral extension of the cushion support member. The trundle bed defines a bolster support surface to receive two bolster members that normally form a back cushion for a sofa by superimposed positioning into a face-to-face arrangement. The bolster members are hinged together and have a thickness such that, when positioned side-by-side on the trundle bed, there is formed an extension to the sofa cushion and thereby forming a bed. The bolster members, sofa frame and trundle bed are usable separately as beds and combined as a sofa with the trundle bed usable separately.
