Our origin story
Sleep Fitter was born from a deep understanding of healthcare and a passion for solving real sleep challenges. Founder Win Hansen spent decades at the forefront of patient care innovation, especially in pressure and temperature regulation. His experience led to the development of Rairflow®—a consumer sleep product based on patented hospital-grade technology that actively moves air under the body to reduce overheating and night sweats. As he sought to bring this solution to market, Win realized that poor sleep is often a symptom of multiple underlying factors. That insight sparked the creation of the Sleep Fitter Method, a holistic approach that combines personalized assessment, education, and passive interventions to improve sleep health at scale. From this, Sleep Fitter has grown into a company with a mission to transform the way people understand and improve their sleep—at home, at work, and in care settings.
