Technical details
TEKNO Leather
Our leather is produced from best quality hides, aniline-dyed and surface treated to provide maximum resistance to dirt and a high degree of colours fastness over time.The leather is very attractive visually as well as being very comfortable to sit on.
All leather has some natural imperfections, caused by insect bites, minor scratches, barbed wire cuts ect. These individual features are unique to each hide and help to distinguish real leather from syntetic man-made materials.Leather is a natural product wich has been used in furniture for hundreds of years.Once used, leather acquires the rich patina of age wich gives your furniture its own unique personality.

Hide specifications
The leather is cattle hide coming from Northern Europe, vegetable-tanned following the most modern processes using non-toxic, environmentally-friendly products. The hides supplied are certified confirming that they are suitable for furnishing and have a Class 1 IM fireproof certificate. Leather thickness is 2.5 / 2.8 mm.
Alcantara specifications
Alcantara always offers its best. Not only in terms of refiniment and class, warmth and comfort, but also practicality, because simple maintainance guarantees its consistently high quality performance and appearance.Natural detergents, even soap and water, are enough to remove any type of stain and restore Alcantara’s refined and elegant look.

Chrome specifications
After an accurate polishing of the steel structures, the products undergo a galvanic bath with an average nickel thickness of 27-28 microns and an average chrome thickness of 20 microns. Such a process gives the final product a high quality finish guaranteeing durability of the chromed surface and protection from oxidation.
Furniture padding specifications
The raw material (expanded polystyrene) of the padding is produced by Bayer, 100% inert-free expanded resin. Fireproof padding (Class 1 IM) is also available upon request.
