Independent testing

Research and development

From concept to finished goods, every step of the way is scientifically researched and tested.

Step 1. Understanding our physiological sleep needs by working together with sleep experts across Europe and the US.

Step 2. Developing the right sleepwear to meet our physiological needs. Together with material scientists and designers from various academic institutions.

Step 3. Prototyping together with leading partners across Europe.

Step 4. Independent testing. All collections are tested in laboratory with both flat testing and torso testing. We also test in climate chambers as well as with test people.

Step 5. Quality control. Before garments are sent to our distribution centers they are checked by an independent quality institute.
