A study that took place in Japan’s Ota Memorial Sleep Center and evaluated mattress material effects on sleep and sleep-related physiological parameters including brain wave and core body temperature has been published in a peer-reviewed journal. The study is funded by Airweave, inc, and led by Seiji Nishino, MD, PhD, emeritus professor of psychiatry and behavioral sciences and director of the Sleep and Circadian Neurobiology Laboratory at the Stanford University School of Medicine. It is published in PLOS ONE.


Here’s the body temperature comparison of airweave airfiber mattress topper versus memory foam.

The study found that sleeping with a high-rebound mattress topper compared to low-rebound mattress topper induced a larger decline in core body temperature in the initial phase of nocturnal sleep both in young and old subjects, and declines in the temperature were associated with increases in deep sleep/delta power (+27.8% in young and +24.7% in old subjects between 11:00–01:00). The researchers also found also found significantly smaller muscle activities during roll over motions with high-rebound mattress toppers during a separate daytime testing.

“I am truly delighted to hear that this sleep study has been accepted for publication in such a renowned scientific journal,” says Motokuni Takaoka, president and CEO of Airweave Inc, in a release. “It is my hope that this publication inspires researchers around the world on the subject of improving sleep quality, which we have dedicated years of study, and the importance of ‘Quality Sleep’ to be widely recognized outside Japan.”
