I had put up with menopausal night sweats for probably about a year and lately they had started to get really bad. My tossing and turning was also affecting my husband's sleep too. I'd read a review on Fifty & Fab and researched wool duvets too. I was a little off put by the price involved but as I was feeling at the end of my tether and dreading going to bed every night I placed my order. I ordered the warmest one as my husband is always cold at night. Literally from the first night we slept better and by night 3 I was sleeping through without even waking. I will be ordering a light one for spring and summer. We go to bed every night and discuss how wonderful and luxurious the duvet is!!
