About Us
The Original Sleep Fitter™
Rairflow, Inc, dba Sleep Fitter™ founded by Win Hansen in 2023, has obtained exclusive licenses for 10 patents from a $3.2B global medical manufacturer, paving the way for revolutionary bed products. Inspired in 2012 by his wife's battle with cancer and the challenges she faced with night sweats and temperature regulation due to chemotherapy, Win brought home a hospital coverlet from his medical company employer. Witnessing significant improvements in her sleep quality, Win became determined to share the microclimate technology with a wider audience.
Rairflow® by Sleep Fitter™ is on a mission to bring affordable, unparalleled sleep health program to individuals, business and patients, driven by the belief that better better sleep health in bed leads to better lives.
