My friend told me about their wool duvet from the Wool Room and so I looked into this as I no longer sleep as well as I used to - mainly due a health issue causing me to overheat, especially at night while lying down. I ordered a duvet and pillow and, having tried it for a month now, I've just ordered a mattress cover too. I'm delighted with the results and can vouch for the fact that the use of wool really does help regulate your temperature while sleeping. Aside from this, the quality of the product and the level of service received is excellent and I have no hestitation in recommending both. Thank you Wool Room! :)
