Sleep Study report: Sleep Better with Wool "Total Comfort Rating" Proves It! It's official! A ground-breaking research study has established that wool bedding products are conducive to a good night' sleep. The Sleeping Comfort Study - conducted by The Woolmark Company and the University of Sydney, funded by Australian Wool Innovation - has shown that through the development of a Thermal Comfort Rating System, wool is the natural choice for bedding products. Combining human and laboratory trials, the study examined more than 30 wool and non-wool 'over' and 'under' body bedding products by testing them in a range of temperature and relative humidity environments to establish a rating of sleeper comfort. And, wool was the undoubted winner with a clear demonstration that wool bedding products:

* Breathe more naturally than synthetic products

* Increase the duration of the most beneficial phase of sleep known as REM, or Rapid Eye Movement

* Regulate body temperature by ensuring the body gets to a comfortable sleeping temperature more quickly - and stays there for longer
