Together We are Committed
After years of research for more sustainable ways to create furniture, lighting, and objects, we now work with a range of production partners with the same ambition as us, creating partnerships for change and supporting the United Nations Sustainable Development Goals.Together we are committed to searching for new and better ways of making beautiful design - in a responsible way.Sørensen ULTRA Leather
One of the most versatile Protected leathers around, ULTRA is the perfect everyday type of leather. Buffed and embossed and genuinely soft to the touch, the surface features a uniform grain pattern over the entire hide, which gives it a consistent look.ULTRA leather has some additional excellent attributes. Its highly durable protective finish makes it very easy to maintain. Stains don’t even leave a mark once wiped away using a fresh cloth with water. What’s more, as leather with heavy surface protection, ULTRA will take longer to show signs of aging or fading due to exposure to light. Add a selection of great colors, from warm, earthy tones and numerous neutrals to a few more vivid colors.
Our ULTRA collection has passed special testing of TVOC (Total Volatile Organic Compounds). Called ANSI/BIFMA M7.1-2011 (R2016), it measures emissions and other factors as to their effect on air quality. A TVOC certificate guarantees that no harmful emissions are released into the environment, thus contributing to a healthy indoor atmosphere.
Leather
As a natural material, leather requires looking after. If you care for the leather correctly, it will become even more beautiful over time. Here are a few tips: Our leather is ready for you to use as soon as it arrives, so there is no initial need to treat or clean it. Over time, if you need cleaning, use a vacuum cleaner once or twice a month with a soft brush to remove any dust. Once or twice a year, use the foam from soap flakes stirred in warm water for a thorough cleaning. Apply the foam with a soft dry cloth, minimizing any contact with water. Avoid bar soap, saddle soap, leather cleaners, household detergents, or chemical products. Protect from direct sunlight, excessive heat, and sharp objectsThe care and maintenance of leather will always depend on the specific way it is used, its conditions, and how often it is used.
Wood & Steel
The frame steel and wood have protective finishes. The use of "wood cleaners" and protectors is advised against. For cleaning and maintenance, use a dry cloth or feather duster. Use a warm, damp, soft cloth to clean dirt and tough-to-remove dried spills. Promptly dry the surface.
