Biss provides an excellent solution when space is limited. It consists of two completely independent single beds. Both are fitted with fixed slats with rigidity adjustment and the removable covers are available in fabric, leather or Ecopelle. The base of the top bed, complete with headboard, can be opened and used to contain the second bed. There is no headboard attached to the second bed, which is fitted with wheels to facilitate movement. Two versions are available: one can be raised from the floor, thanks to a piston device; the other remains at floor level and cannot be raised.
