Scientific Validation
Using Differential Scanning Calorimetry (DSC), we ensure Outlast® technology is applied correctly and meets our strict quality standards, alongside additional testing to guarantee product functionality.
Independent tests with THG SleepView show that duvets with Outlast® PCM fiber reduce humidity by 48% compared to traditional duvets, preventing moisture buildup for better comfort. INSIDE CLIMATE GmbH, led by C. Russ, used THG AreaView technology to confirm Outlast®’s superior moisture reduction.
A study at Shinshu University found that Outlast® mattresses resulted in fewer body movements, deeper sleep, and greater refreshment, compared to standard mattresses, which caused overheating and disrupted sleep.
