The Secret of Longevity

Raw Material


The origin of the OTQ brand lies in its material genesis: cork. In the Sardinian language, it literally corresponds to the material itself: cork. The genesis of OTQ started here: a semantic journey which represents a production, manufacturing, and generational cycle. The tree sprouting from the soil; the tree that generates the cortex; the tree that preserves itself along the identity process of extraction.



The Cork

The root

Cork is landscape, the outline of sunsets, it is lunar shadows, theatrical tree, creator of charming splendour and plays of colours. But it is also fauna that settles and flora that finds refuge. Cork has been Sardinia from its ancient origins, a native stump that dates back to approximately sixty million years old.


The process of extraction from the tree allows keeping the trunk alive, which is not affected by the separation and it is ready to produce again over the years, reinforced and reinvigorated in a continuous journey of resilience.

Not only design

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 destabilising action of magnetic and electrostatic flows.

Culture of sleep


Sleeping in harmony surely represents a safe way to prevent stress, live better and longer. BISU is the most innovative solution: it is a bed with an engineered set of proportions, both from the functional and aesthetical point of view, in order to regulate the rest and heal the well-being of the body.

A journey of innovation

There is an island in the heart of the Mediterranean Sea where one of the most consolidated realities in the wood manufacturing has its roots. It is the Sardinia island, a thousand-year old land of know-how and well-established dedication to production, where three generations of artisans of the company “Sud Legno” have been passing down the art of carpentry from father to son in an ever-lasting relationship of passion and quality
