EVERWARM® weighs more and tests first for softness compared to other cotton flannel sheets. EVERWARM® also ranks highest for warmth (most heat insulation) and smoothness, making it one of the top three sheets in our rigorous testing process.
In our RealFeel lab, we evaluate eight key qualities—temperature, breathability, weight, body, texture, suppleness, friction and moisture transference—after all chemical softeners are washed out. Unique algorithms identify sheets scoring highest in softness and temperature control, particularly in ensuring warmth and dryness over time.
Comfort is subjective but objective testing can measure it. Companies like Nike use methods to evaluate fabric quality and performance. Sheets.com uses similar tools and tested over 150 different sheets for softness and temperature control.
