CONVERTIBLE FURNITURE UNIT

A convertible furniture unit constituted by a sofa having an exposed wall and that can be converted into a folding double bed or into two mutually separate single beds. The conversion from double bed to two single beds occurs in the day version, with the beds arranged vertically, by virtue of the sliding movement on a rail of the two portions. The spring-based balancing system, the levers and the fulcrums of rotation are inside the supporting structure. The shoulders of the piece of furniture that embed the sprung bases in the day position are fixed to the sprung bases themselves and, by rotation, become the side boards of the bed in the night position; in this manner, the unit does not have, in the night version, the appearance of exposed wall-mounted furniture. The unit also allows, in the day version, to join without gaps the two seats into a sofa and, in the night version, to join the two single beds to form a double sprung base.
