Transformable furniture systems with foldable queen-sized bed that opens vertically, with innovative, patented slatted base (CF09), and with or without a sofa. The Penelope model (depth 350 mm) must be anchored to the wall. The Penelope Sofa model is self-supporting: the sofa mounted on the front disappears when the bed is opened. The bed base opens and closes with a simple movement using a specific device inserted into the foot. Safety is guaranteed by the automatic blocking system that can be inserted both horizontally and vertically, which prevents accidental opening and closing.
