Furniture Design Bisu Bed by Matteo Congiu Bisu is the first cork bed in the world which is capable to join functionality, ethics of well-being and design. The absence of metallic components, the naturalness of cork, its antistatic properties protect the sleep from the destabilizing action of magnetic and electrostatic flows. The presence of electrostatic and electromagnetic flows represents one of the most common enemies for the quality of our rest. Bisu, with the properties inherent in cork, eliminates the negative action of any exogenous force, restoring quality and balance to healthy sleep.
