    Abstract: A seating- and sleeping-furniture piece, which comprises a framework and a cushion swingably mounted on the framework. The cushion is adapted to form in a seating furniture a backrest in its backward upwardly swung position, and to form in a sleeping furniture a wedge cushion in its downwardly swung position. Two cushions are disposed on a carriage capable of rolling-in into and rolling-out from the framework. The cushions are disposed on top of each other in the seating furniture and during their rolling out and under-grip in the seating position the cushion swung upwardly as a backrest and rolling out so far in the one bed position under the cushion swung upwardly as a backrest, that the forward bottom edge of the backrest and the rear edge of the seating- and the laying-cushion are disposed vertically on top of each other, and in the double bed position, the two seating- and laying-cushions are disposed one behind the other, and capable of being laid down in the double bed position following the cushion swung forward downwardly as a wedge cushion with the formation of a double laying face. The carriage comprises two telescope-like parts displaceable relative to each other. The inside disposed of the parts defines a bedding chamber, which has an engagement face for the upper of the seating cushions in its use as laying cushion, as well as have an engagement face for the wedge cushion, and is supported on the floor. The outside disposed part is supported on the floor on the front and at the rear by means of rollers on the inside disposed part, and forms an engagement face for the lower seating- and laying-cushion. A cover receives a wire insert to form an upper closure for the bedding chamber, and is swingably mounted in a frame. The frame is swingably mounted on the inner part of the carriage and is equipped with slide pins. The framework includes obliquely rearwardly disposed grooves which secure the slide pins. Roller means are formed on the outer part of the carriage, and side parts of the frame are formed as sliding faces for the roller.
