I have had issues with mild night sweats and body heat fluctuations for several years after suffering with anxiety and depression a decade ago. I've had high quality down duvet but it didn't keep a stable temperature. My partner bought a Wool Room duvet and mattress topper a year back, and thinks very highly of them. She feels the cold and so needs almost the opposite qualities to me. So I have now bought a full set, including pillows. I can say that I was mildly skeptical that my sleep would be up to 25% better, and yet i do feel much more rested and ready for the new day when I wake. The mattress enhancer is soft and adds extra comfort as well as adding to the overall temperature control. And the pillows are wonderful too. I wanted the organic cotton covers as spending almost a third of life in bed, and the potential damage that agricultural chemicals can do to the human, I feel that is an important factor (a shame that all the Wool Room ranges don't have this as an option). I have added a silk pillowcase to the setup, and find that using the 300gsm provides ample warmth even during the winter months. I have given the second pillow and 200gsm to my 90 year old mum who has a single bed, and doubled over she finds the duvet wonderful. She wants a mattress enhancer to complete the set now. Thank you to Wool Room for having the vision to provide great quality from sustainable and reputable sources and help make lives better, all by sleeping on (and under) it.
