I have not been sleeping well for years and have tried absolutely everything : acupuncture, herbalism, silk sheets, ( nice !) etc etc etc . However, nothing has really worked until now, and actually I used to dread going to bed. Therefore the wool duvet has come as something of a miracle. I have only had the duvet for about 10 days, and last night didn't need to get up in the night to go to the toilet for the first time in many years. I am still waking up in the night, but going back to sleep much more quickly, and feeling so much more comfortable and relaxed. It is no exaggeration to say it has changed my life. Thank you for a truly wonderful product.
