We were both suffering with over-heating and night sweats due to a polyester hollowfibre duvet. I came across this website and, having read all of the reviews, decided to by a classic warm duvet and so pleased that we did! Sleeping much better and with a lot more comfort. Highly rate this product - warm and comfy. Service from the Woolroom was very good - order despatched in short time and packaged very well in a waterproof protective wrapper - which was just as well as the parcel was left on our doorstep during the huge storms of Friday 12th October, despite instructing courier to leave parcel with a neighbour!
