I really dithered for ages about purchasing a wool duvet ( I went for the all-season) and pillow protectors as the total cost was expensive but I am so pleased that I went for it - the sale decided me. As a 'woman of a certain age' I have suffered from being too hot then, having thrown the duvet off, too cold at night for months and I can quite honestly say that I've had the best nights sleep since using my new duvet than I've had in ages. It takes a couple of nights to get used to the slightly thinner feel of the duvet but it is so cosy and it feels just right. If you, like me, are undecided I say - Go for it!
