  • A primer on temperature-regulating mattress components

    Ben Welter - Monday, February 02, 2015

    BedTimes magazine, "the business journal for the sleep products industry," offers a 2,000-word primer on the challenge of regulating temperatures in today's all-foam and hybrid mattresses. 

    “Companies are becoming more innovative with the applications they use PCMs in — from fabrics to foams to gels and fill,” said Joe Wehrle, director of sales for Microtek Laboratories Inc. “The mattress marketplace is experiencing the cooling/warming effects that PCM technology provides, helping to create the ‘perfect sleep experience’ that end users value. Every day, new and inventive products are being introduced in the bedding segment which capitalize on the thermal benefits of phase change materials.”
