Abstract
Abstract A convertible sofa bed is disclosed and claimed herein where the rear side of the sofa back is provided with a cushioned surface and the back is pivotal forwardly to expose the rear cushioned side, thereby converting the device into a single bed. The sofa bed basically comprises three components, namely, a base, end sections and a back. The base is provided with two back supporting sections, one of which is at the rear and above a seat support section on the base while the other is at the rear and below the seat support section. The back is supported intermediate its length by the upper support section and at the bottom by the lower support section so as to provide complete support for the back in the upright position. Pivot means are provided along at least a portion of the length of the back so as to permit pivotal movement of the back around the upper support section. Preferably, the back is sized with relation to the base and end sections so as to substantially fill out the cross sectional area of the sofa in the closed or bed position. In other words, the height of the back is substantially equal to the width of the base while the length of the back is substantially equal to the length of the base and resides between the end sections.
