Our Story

"When industry insiders told me that retail and mattress manufacturing didn't care about selling outcomes with Rairflow®, I knew we had to solve a problem for consumers in a way that also benefited retailers."— Win Hansen, Founder of Sleep Fitter & Inventor of Rairflow®

Rairflow® was born from a promise. In 2012, while teaching hospitals across America about thermoregulation, I brought home patented reverse airflow technology to help my wife through cancer treatment. Watching her finally sleep through the night, I vowed to make this hospital-grade solution available to everyone. A decade later, I secured exclusive licensing to ten patents from a $3.2 billion medical company and launched Rairflow®—the only consumer product that pulls hot air OUT from under your body instead of blowing air ON you.

When the mattress industry told me they didn't care about outcomes—just quick sales and "trunk slamming" customers out the door—I knew we had to build something different. Sleep Fitter's digital platform puts consumers in control, helping them understand their sleep needs privately before ever stepping into a store. We're teaching the world the difference between marketing gimmicks that "feel cool" and true thermoregulation that actually works. It's healthcare expertise made accessible—for consumers AND retailers who commit to outcome-driven selling.
